Anthropic 'clear leader in AI', says Musk. Here's what the SpaceX chief really means
Elon Musk does not often admit he was wrong. But he has. Responding on X to a user who noted that SpaceX controls the computing power Anthropic depends on, and could, in theory, cut it off, Musk said he never would. He went further, calling Anthropic the clear leader in AI and saying no rival had shipped a model as good as its Mythos and Fable systems. He expects a Mythos 2 before long. The turn is surprising, given that last September, he wrote that winning was never a possible outcome for Anthropic. In February, after it raised $30bn at a $380bn valuation, he called its models "misanthropic and evil" and told it to fix them. Five months on, the same company is his benchmark for the field. The praise is not free Take the compliment at face value and it reads as rare humility. Look at the plumbing and a second motive appears. In May, Anthropic agreed to lease the entire output of xAI's Colossus 1 data centre near Memphis, about 300 megawatts, paying roughly $1.25bn a month through 2029. That is close to $40bn flowing to Musk's side of the table. He is not just admiring Anthropic. He is billing it. A rival who pays you $40bn is a rival worth flattering. Musk's pledge not to weaponise that dependence costs him nothing and buys goodwill with a customer he needs. The admiration may be real. It is also good business. Playground politics? The sharper reading sits one company over. Musk co-founded OpenAI in 2015 as a non-profit, left the board in 2018 after the others refused to hand him control, and has fought it since. He sued Altman and OpenAI in 2024, accusing them of abandoning the founding mission for private gain. He sought more than $150bn in damages, Altman's removal and the unwinding of the for-profit structure. In May, a jury threw the case out, finding Musk had waited too long to file. He called the verdict a "calendar technicality" and vowed to appeal. By July, the feud was personal again. Musk branded Altman "Scam Altman" after Apple sued OpenAI, and Altman replied that the surest sign his new model led the field was that Musk was obsessed with him again. Against that backdrop, crowning Anthropic the leader does double duty. It is a real judgement about the models. It is also a way to tell the market that the AI company that matters is not the one he is suing. Both are racing to the same finish line Timing sharpens the point. Both firms filed confidentially for stock market listings in June, within days of each other. Anthropic, valued at about $965bn in private markets, is pushing for a Nasdaq debut as early as October. It could be the first company to list at close to $1tn, and it expects its first profitable quarter, with around $559m in operating income on $10.9bn of revenue.

Anthropic launches India pricing for Claude AI Pro and Max plans
AI major Anthropic has started rolling out pricing in Indian currency for users in one of its key markets. Users of Claude are now seeing Indian pricing for Anthropic's AI chatbot across its Pro and Max variants. Anthropic's website now shows that Claude Pro costs ₹2,000 a month (~$21) on annual billing or ₹2,399 a month on monthly billing. Claude Max is available at ₹11,999 a month for Max 5x and ₹23,999 a month for Max 20x. The free tier still remains available. These prices include GST. In the US, the Pro plan is listed at $17, while the Max plan is listed at $100. This puts India's prices at a marginal premium, most likely due to currency conversion charges at Anthropic's end. With this, Anthropic is now priced the same as ChatGPT Plus in India, which is listed at ₹1,999/month. However, unlike its rival OpenAI, which allows UPI payments for its services, users can only pay for Anthropic via credit or debit cards and Play Store/Apple Store payment options. India emerges as a key growth market for Anthropic Anthropic's move follows the growing recognition of the Indian AI user base by global AI companies, which are now tailoring their products to offer convenient billing and payment options. While it is not special / lower pricing for Indian users, it addresses the friction caused by dollar pricing and currency conversion that Indian users faced earlier. India is Anthropic's second-largest market outside the US, accounting for 5.8% of total Claude.ai use, second only to the United States, as per Anthropic's disclosures in February, 2026. The company opened an office in Bengaluru earlier this year and appointed former Microsoft India executive Irina Ghose to lead its business here. Anthropic has been partnering with a slew of Indian IT firms, including Tata Consultancy Services and Infosys, in recent months to scale enterprise AI use cases. The company did not respond to queries on India pricing. Claude's responses vary across languages, says Anthropic Separately, Anthropic released an analysis on Monday denoting how the values Claude expresses vary across languages. When Claude speaks in English, it emphasises different values than when it speaks in Portuguese, Indonesian, or Chinese, the AI company said. "The largest variation is in the Warmth vs. Rigor axis, with Claude leaning toward expressing warmth-related values most in Arabic and Hindi and rigor-related values most in English and Russian," it added.

Anthropic rolls out India pricing for Claude subscription plans The Mainstream
Anthropic has reportedly started displaying India-specific pricing for its Claude AI subscription plans, marking another step in the company's growing focus on the Indian market. According to a report by a technology publication, the updated pricing is visible to some users in India, although payments through the Unified Payments Interface (UPI) are not yet available. Users can currently subscribe using bank cards or the billing systems of the Apple App Store and Google Play Store. India has reportedly become Anthropic's largest market outside the US. The company opened its Bengaluru office in February and has partnered with Indian IT companies, including Infosys and Tata Consultancy Services, to expand enterprise AI deployments. For individual users, Anthropic offers 2 subscription plans. The Pro plan is priced at ₹2,000 per month when billed annually, while the Max plan costs ₹11,999 per month with annual billing. The Team plan starts at ₹2,399. According to the report, all Indian prices include local taxes. For comparison, the Pro plan is priced at $17 per month in the US, the Max plan costs $100, and the Team plan starts at $20. The Free plan provides access to Claude on the web, iOS, Android, and desktop. It includes web search, desktop extensions, voice mode, incognito chats, user preferences, artifacts, file creation and editing with code execution, memory, connectors, and skills for reusable instructions. Free users can access only the Sonnet and Haiku models. The Pro plan includes everything in the Free plan, along with higher usage limits and access to advanced features such as Claude Code, Claude Cowork, Claude Design, projects for organising chats and documents, additional Claude models, and Claude for Microsoft 365. The Max plan offers all Pro features with significantly higher usage limits. Subscribers can choose between 5x or 20x the Pro usage per 5-hour session. It also provides higher output limits and priority access during peak usage periods.

"Stop the AI Race": Hundreds March Against OpenAI, Anthropic and Google DeepMind in San Francisco
On Saturday, July 11, around 400 people took to the streets of San Francisco to protest against the leading AI companies. The march, held under the banner "Stop the AI Race", led from OpenAI's headquarters on 3rd Street past Anthropic's offices on Howard Street to Google DeepMind's location at Rincon Park, with rallies and speeches at each stop. The organizers emphasize that this was a peaceful assembly of "concerned citizens, families, and researchers" - and that employees of the companies in question were explicitly invited to join. The Central Demand: A Conditional Pause on Development The movement has a single, clearly defined demand: every CEO of a major AI lab should publicly commit to pausing the development of frontier models - on the condition that every other major lab in the world credibly does the same. This is not a call for a unilateral stop, but for a conditional pledge along the lines of: "If the others pause, I will too." In practice, according to the organizers, such a pause would mean: no new training runs for larger or more general frontier models. Teams currently working on advancing the capabilities of these models would instead shift to narrow AI applications or alignment research. Existing models would remain available, and narrow AI applications would still be permitted. As a technical blueprint, the movement points to a paper by the MIRI Technical Governance Team that outlines an international agreement led by the US and China - including verification mechanisms such as AI chip tracking and compute thresholds (FLOP caps). The Warnings: "The Architects Know the Race Is Reckless" The protesters argue that the leaders of the AI companies themselves have repeatedly warned about the existential risks of their technology - for instance in public statements on AI risk signed by numerous industry figures. At the same time, they say, each lab justifies its pace by claiming it must beat the competition and geopolitical rivals. It is precisely this race that the activists want to break. Asked about China, they respond that any agreement would of course have to include all major AI labs worldwide - but public commitments from Western CEOs are the first step toward the kind of international coordination that would make this possible. The movement has a history: in September 2025, an 18-day hunger strike outside Google DeepMind's London offices made international headlines. DeepMind CEO Demis Hassabis responded at the time and signaled openness to a conditional pause, but named international coordination as the key bottleneck. In February 2026, from the activists' perspective, Anthropic removed the commitment to pause development if its own AI became too dangerous from the third version of its Responsible Scaling Policy - prompting a first march on Anthropic, OpenAI and xAI on March 21. Since then, Anthropic has written that it expects it "would slow down or temporarily pause" development if other labs verifiably did the same, and OpenAI stated in a strategy paper that coordination, including slowing frontier development, is expected to become more important. For the organizers, this is not enough: "expects" is not a commitment - what is needed, they say, are binding pledges along with a concrete verification regime. Background: Attacks on Sam Altman's Home The protests are taking place in an increasingly heated climate. In April 2026, the San Francisco home of OpenAI CEO Sam Altman was targeted twice within a matter of days: first, a 20-year-old from Texas threw a Molotov cocktail at the property and subsequently threatened to burn down OpenAI's headquarters. According to prosecutors, the man was driven by hatred of AI technology, traveled to San Francisco with the intent to kill, and was carrying a manifesto containing the names and addresses of other AI executives and investors. He was charged with, among other things, attempted murder. Just two days later, shots were fired at Altman's house from a car; two people were arrested, though it remains unclear whether the attack was deliberately aimed at the property. No one was injured in either incident. Altman himself responded with a blog post in which he shared a photo of his family and called for de-escalation: fear about AI is justified, he wrote, and criticism of the industry welcome - but rhetoric and tactics need to be dialed down. The "Stop the AI Race" organizers, for their part, clearly distance themselves from violence and are committed to peaceful protest. Background: Resistance to AI Data Centers Across the US In parallel, resistance to the massive buildout of AI data centers is growing across the United States. According to a report by Data Center Watch, projects worth around 130 billion US dollars were blocked or delayed in the first quarter of 2026 alone - at least 75 projects, the highest figure since tracking began in 2023. In the first six weeks of the year, lawmakers from both parties introduced more than 300 data center bills, and 14 states proposed construction moratoriums. So far, opponents have had the greatest success at the local level: more than 100 municipalities across the US have imposed construction pauses - including Denver with a one-year moratorium, Oklahoma City and Tulsa, several communities in Illinois and Georgia, and around 20 municipalities in Michigan. At the state level, Maine narrowly missed becoming the first state in US history to enact a statewide moratorium in April, when Governor Janet Mills vetoed the bill. In New York, the legislature passed a one-year moratorium on AI data centers in June, which is currently awaiting Governor Kathy Hochul's signature. At the federal level, Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez introduced the Artificial Intelligence Data Center Moratorium Act in March, which would halt the construction of new data centers of 20 megawatts or more until national safeguards are in place. According to a Gallup poll, roughly seven in ten Americans oppose the construction of AI data centers near their homes. The "Stop the AI Race" movement, meanwhile, is announcing further actions. As its website puts it: protest marches are "just the start".
Former Fed Chair Bernanke Joins Anthropic's AI Oversight Body
Benzinga and Yahoo Finance LLC may earn commission or revenue on some items through the links below. Anthropic has hired former Federal Reserve Chairman Ben Bernanke to its long-term benefit trust (LTBT), an AI oversight body tasked with ensuring the company remains accountable to its broader public interest goals. In his role, Bernanke will provide guidance on the potential risks and societal impacts of AI, as well as how AI is changing the economy. He will also lead insight into Anthropic's economic research, in addition to other areas of the artificial intelligence company's work, Anthropic reported. "The potential of artificial intelligence is enormous, and so is the range of outcomes. How that potential plays out will depend, in part, on the institutions we build around it," Bernanke said. "Anthropic has created a unique governance structure to try to ensure that the long-run benefits of AI for humanity far outweigh the risks. I am honored to have this opportunity, and I will try to contribute in any way I can to this critical mission." Anthropic operates as a Public Benefit Corporation, a structure designed to pursue financial growth while also advancing broader societal interests. The LTBT was established to help preserve that balance over time by providing oversight and ensuring the company remains accountable in how it builds and deploys AI systems, "AI may have the most significant economic effects of any technology in modern history, and Anthropic has a dual responsibility to understand those effects and to act on them," said Daniela Amodei, Co-Founder and President of Anthropic. "Ben's career has run from studying how economies react to disruptive moments to helping steer the world's largest economy through one such time. His judgment will make us better at anticipating and responding to how advanced AI affects workforces and economies around the world."

Before joining the Federal Reserve, he spent more than two decades as an academic economist and earned a Nobel Prize in Economic Sciences in 2022. On the LTBT, Bernanke will be joining the CEO of the Clinton Health Access Initiative, Neil Buddy Shah, the CEO of the Center for a New American Security, Richard Fontaine, and Mariano-Florentino Cuellar, who joined Stanford University's Center for Advanced Study in Behavioral Sciences this month.
Tuesday newspaper round-up: North Sea oil, Anthropic, EV owners
The US government has already paid back tens of billions of dollars in tariffs it collected before the supreme court ruled them illegal, according to budget figures released on Monday. Tariffs - taxes on imported goods - have been a key part of president Donald Trump's game economic plan since he took office again last year. But in February, the supreme court shut down a big chunk of the extra tariffs Trump ordered, forcing the government to return money to the companies that had paid them. - Guardian The UK's North Sea oil industry has made a last-ditch attempt to curry favour with the Labour government by appealing to Andy Burnham's reindustrialisation agenda just days before he is expected to become Britain's next prime minister. Industry lobbyists have written to more than 400 Labour MPs to call on the government's new leaders to allow more oil and gas drilling in UK waters to support homegrown energy and show "a commitment to UK manufacturing, industrial capability and the skilled workforce that has powered the nation for generations". - Guardian The founder of online bank Monzo has become the latest high-profile figure to join Anthropic, the AI company behind the Claude chatbot. Tom Blomfield, who is one of Britain's most successful tech entrepreneurs, will take a leave of absence from his current role at start-up investor Y Combinator to join Anthropic, which recently overtook OpenAI as the world's most valuable AI company. - Telegraph Electric vehicle (EV) owners will be taxed for driving abroad under Labour's pay-per-mile plan. In a consultation response published on Monday, the Government said charging drivers for overseas mileage was proportionate because not doing so would require the use of location data to show where they were - raising privacy concerns. - Telegraph The United Arab Emirates is building another port in an attempt to bypass the Strait of Hormuz, having already expedited the construction of a new oil pipeline. The new port would join an existing facility in Fujairah along the country's eastern coastline and past the tip of the strait that Iran closed to shipping during the war with the United States. - The Times
Anthropic Starts India Pricing For Claude AI, Pro Plan At Rs 2,000
The pricing update underscores India's growing importance for Anthropic File photo Anthropic has started introducing India-specific pricing for its Claude AI assistant, allowing users to pay for subscriptions in rupees instead of US dollars. The move is expected to make the chatbot more accessible to Indian users and marks another step in the company's growing focus on what it now describes as its second-largest market after the United States. Indian users are beginning to see local pricing across Claude's paid plans on the web and mobile apps, eliminating the need for dollar-denominated payments and reducing the friction associated with international transactions. The localisation comes as global AI companies race to expand in India, one of the world's fastest-growing markets for generative AI. Under the new pricing, Claude Pro will cost Rs 2,000 per month with annual billing, or Rs 2,399 per month if billed monthly. Anthropic has also introduced two Claude Max tiers priced at Rs 11,999 and Rs 23,999 per month, offering significantly higher usage limits for developers, researchers and power users. Businesses can subscribe to the Claude Team plan from Rs 2,399 per user per month on annual billing, while the Premium Team tier is priced at Rs 11,999 per user per month. All prices include GST. The pricing update underscores India's growing importance for Anthropic. The company says India has emerged as its second-largest market globally after the US, accounting for 5.8% of Claude's worldwide user base. Earlier this year, CEO Dario Amodei said Anthropic's revenue run rate in India had doubled in just four months, highlighting the rapid pace of AI adoption in the country. Anthropic has been steadily expanding its presence in India. In February, the company opened its first office in Bengaluru and has since increased its focus on developers and enterprises. The company has also partnered with fintech firm Razorpay to make Claude more accessible to businesses building AI-powered products and services. The latest move comes as competition in the AI assistant market intensifies. OpenAI, Google, Microsoft and Perplexity have all stepped up their efforts in India through new products, partnerships and enterprise offerings. By introducing local currency pricing, Anthropic is lowering one of the biggest barriers to paid subscriptions while signalling that India is becoming central to its long-term growth strategy.

Sam Altman can't stop making fun as Claude maker Anthropic 'goes around America' to ask people 'hard question on AI'; says: I thought this was ...
OpenAI CEO Sam Altman has mocked rival Anthropic's new advertising campaign that asks people to share their concerns about AI. Anthropic launched the campaign under the theme "There's hope in hard questions," encouraging people to ask difficult questions about AI's impact on jobs, families, science and society. The Claude maker said it wants to better understand public concerns and will publicly track the steps it takes to address them. However, Sam Altman responded with a series of sarcastic posts on X (formerly Twitter), saying he initially thought the campaign was a parody."i thought this was satire, kept looking for the handle to be spelled c1audeai or something," Altman wrote in reply to Anthropic's post on X.Continuing his criticism of the campaign, Altman wrote in another post."hard questions are great but only if we deem you worthy enough to not silently downgrade you, or even get access at all"Anthropic said AI has the potential to improve people's lives by making work easier, speeding up scientific research and helping solve major medical and social challenges. At the same time, it acknowledged concerns about job losses, creative work, human agency and the misuse of AI. The company said it is launching a new initiative to better understand these concerns and has invited people to submit their toughest questions about AI.According to Anthropic, it has already surveyed 52,000 Americans about their hopes and concerns around AI, collected responses from 81,000 Claude users across 159 countries and 70 languages, conducted in-person focus groups and studied anonymised real-world Claude usage data.The company said it will publicly report the actions it takes to address these questions and be transparent about where it falls short of its goals.
OpenAI CEO Sam Altman Throws Shade At Anthropic's New Ad Amid Tussle With Elon Musk, Apple: 'Thought This Was Satire'
* Altman took a swipe at a new advertisement for Anthropic's Claude. * In the past few days, he has again rebutted Elon Musk and said he is "not afraid of Apple" following the iPhone maker's lawsuit. * Investors are closely watching developments at OpenAI as it moves toward a public listing. OpenAI CEO Sam Altman took a more combative tone toward tech rivals on Monday, days after his AI startup was hit with a major trade-secret theft lawsuit by Apple. "Come for the best model, stay because we don't treat you with contempt," Altman posted on X on Monday, without context. Given the timing, X users interpreted it as criticism aimed at companies like Apple, Anthropic or SpaceXAI. In a separate post, Altman took a swipe at a new advertisement for Anthropic's Claude. The ad, titled "There's Hope in Hard Questions," features a narrator reflecting on whether AI can be built to benefit humanity. Responding to it, Altman wrote, "i thought this was satire, kept looking for the handle to be spelled c1audeai or something." Anthropic was started by former OpenAI employees, and the company now appears to be leading in the AI market. Altman Sharpens The Rhetoric The OpenAI CEO is no stranger to quirky responses to online critics, but lately he appears to be taking a more head-on approach. In the past few days, he's rebutted criticism from SpaceX and Tesla founder Elon Musk, saying that he was wooing public market investors with unproven claims about space data centers and that he is "not afraid of Apple" following the iPhone maker's lawsuit. Altman and Musk have frequently traded jabs online amid Musk's long-running legal campaign against OpenAI, including challenges to its restructuring and its relationship with Apple. Apple Lawsuit On Friday, Apple said it sued OpenAI in California, alleging that OpenAI encouraged Apple employees to share information, components, drawings, and other materials related to upcoming products -- as part of OpenAI's efforts to develop its own suite of devices. The suit also named Tang Tan, a 25-year Apple veteran who joined OpenAI as its chief hardware officer last year, as a defendant. The suit marks a dramatic turn for two companies that were close partners. OpenAI has powered Apple Intelligence and Siri, but ties between the two have frayed over the past year. OpenAI IPO Watch Investors are closely watching developments at OpenAI as it moves toward a public listing, setting up a potential IPO showdown with chief rival Anthropic. Both companies confidentially filed IPO paperwork with regulators last month, before reports emerged that OpenAI may delay its listing until next year rather than the previously expected fourth-quarter timeline. OpenAI now broadly trails Anthropic, based on the most recently disclosed numbers. In April, Anthropic said it tripled its annual revenue run rate to $30 billion, surpassing OpenAI's ARR of about $24 billion. Anthropic is valued at $1.08 trillion, compared to OpenAI's private market valuation of $868.4 billion, according to data from Nasdaq Private Market.

Anthropic launches Claude AI subscription plans in India: Prices start at Rs 2,399, beats ChatGPT Pro
New Delhi: Anthropic has launched local pricing for the Claude AI subscriptions in India, where users can pay in Indian Rupees instead of USD. The foreign exchange charges and bill uncertainties will be eliminated from Indian customers' bills, simplifying the subscription process for developers, professionals, and business users. India is already Claude's second-largest market, accounting for nearly 6 per cent of its global users, making the localisation an important step for the AI company. The price, however, does reflect Anthropic's approach. Unlike OpenAI and Google, which have introduced affordable India-specific plans, Anthropic is positioning Claude as a premium AI service. Local billing makes it easier for 6 per cent more to use, but the company is hoping they'll pay more for the more advanced models and usage caps than for price alone. Claude Pro, Max and Team plans are now available in India Multiple subscription tiers have been introduced by Anthropic with GST-inclusive pricing. The monthly rate for Claude Pro is Rs 2399, and users who pay annual rates pay an effective monthly rate of Rs 1999 per month. AC2399 and models based on Claude's Sonnet 5, Opus and Fable 5 are included in the plan. Claude Max is offered in two versions for developers and heavy AI users. The Max 5x plan will charge you Rs 11,999 per month, while the Max 20x plan will cost you Rs 23,999 per month which also provides much higher usage limits and priority access. The company has also launched a Team subscription for businesses. Team Standard is priced at Rs 2399 per seat per month (billed annually), and Team Premium is priced at Rs 11999 per seat per month (billed annually). Anthropic says such plans will encompass enterprise-focused attributes, including a 200,000-token context window and guarantees that customer data won't be fed into training its AI models. How Claude compares with ChatGPT and Gemini The biggest difference remains affordabilities. If you are looking for the best AI features with a reasonable budget, both OpenAI's ChatGPT Go and Google's Gemini AI Plus feature a monthly subscription cost of Rs 399. Both ChatGPT Plus and Google's Gemini Pro are lower in price than a monthly subscription to Claude Pro, which is priced at Rs 1,999 and Rs 1,950, respectively. Anthropic does have an advantage at the high end. Claude Max 5x offers a lower price at Rs 11,999 per month as compared to ChatGPT Pro pricing by OpenAI at Rs 19,900 per month. Google doesn't have anything like this premium consumer option just now. Another area where Anthropic still trails is payments. OpenAI and Google have integrated UPI payment into their services in India, with Claude still accepting credit card and app store payments for its subscriptions. Overall, Anthropic's pricing in India is not as much about the price and more about the professional community that appreciates the larger context windows, advanced coding skills and higher usage limits. While ChatGPT and Gemini are the more budget-friendly options, Claude is pitching itself as more of a productivity app than an AI assistant for the masses.
OpenAI CEO Sam Altman Throws Shade At Anthropic's New Ad Amid Tussle With Elon Musk, Apple: 'Thought This Was Satire'
* Altman took a swipe at a new advertisement for Anthropic's Claude. * In the past few days, he has again rebutted Elon Musk and said he is "not afraid of Apple" following the iPhone maker's lawsuit. * Investors are closely watching developments at OpenAI as it moves toward a public listing. OpenAI CEO Sam Altman took a more combative tone toward tech rivals on Monday, days after his AI startup was hit with a major trade-secret theft lawsuit by Apple. "Come for the best model, stay because we don't treat you with contempt," Altman posted on X on Monday, without context. Given the timing, X users interpreted it as criticism aimed at companies like Apple, Anthropic or SpaceXAI. See what 10M+ investors are talking about. Get the Stocktwits Daily Rip for what retail is watching right now, free to your inbox In a separate post, Altman took a swipe at a new advertisement for Anthropic's Claude. The ad, titled "There's Hope in Hard Questions," features a narrator reflecting on whether AI can be built to benefit humanity. Responding to it, Altman wrote, "i thought this was satire, kept looking for the handle to be spelled c1audeai or something." Anthropic was started by former OpenAI employees, and the company now appears to be leading in the AI market. Altman Sharpens The Rhetoric The OpenAI CEO is no stranger to quirky responses to online critics, but lately he appears to be taking a more head-on approach. In the past few days, he's rebutted criticism from SpaceX and Tesla founder Elon Musk, saying that he was wooing public market investors with unproven claims about space data centers and that he is "not afraid of Apple" following the iPhone maker's lawsuit. Altman and Musk have frequently traded jabs online amid Musk's long-running legal campaign against OpenAI, including challenges to its restructuring and its relationship with Apple. Apple Lawsuit On Friday, Apple said it sued OpenAI in California, alleging that OpenAI encouraged Apple employees to share information, components, drawings, and other materials related to upcoming products -- as part of OpenAI's efforts to develop its own suite of devices. The suit also named Tang Tan, a 25-year Apple veteran who joined OpenAI as its chief hardware officer last year, as a defendant. The suit marks a dramatic turn for two companies that were close partners. OpenAI has powered Apple Intelligence and Siri, but ties between the two have frayed over the past year. OpenAI IPO Watch Investors are closely watching developments at OpenAI as it moves toward a public listing, setting up a potential IPO showdown with chief rival Anthropic.
Anthropic's extravagant tokenizer complicates AI pricing
Claude looks substantially more token-hungry than OpenAI's GPT-5.x, thanks to the new tokenizer that Anthropic shipped with recent releases. Large language models (LLMs) use tokenizers to handle the mapping of text into tokens. There's no set definition of a token, but they're typically a set of three or four characters that are mapped to the integers LLMs actually process. Tokens have become the basic economic unit for billing use of AI models. Because the slicing of words into tokens and the tokens required per task vary across models, it has become rather difficult to predict the final bill for playing the AI slot machine. Recent changes to Anthropic's tokenizer appear to have further complicated matters by making the same content more costly to process on certain models. Playcode, an AI app building platform, recently analyzed the impact of Anthropic's latest tokenizer and found that the same TypeScript file processed by Claude can consume up to 73 percent more tokens than OpenAI's GPT-5.x model family. Anthropic acknowledges its new tokenizer - announced at the end of June when Sonnet 5 shipped - may generate more tokens for the same input than prior versions. "Sonnet 5 is an upgrade to Sonnet 4.6, but it uses an updated tokenizer that changes how the model processes text to improve performance (this is similar to the tokenizer change we introduced with Claude Opus 4.7)," the company explained. "The tradeoff is that the same input can map to more tokens: roughly 1.0-1.35× depending on the content type." Anthropic offered Sonnet at a reduced introductory rate - $2/million input tokens and $10/million output tokens through August 31, 2026 - to make the inflated token generation more or less cost-neutral. But the price is set to rise to $3/million and $15/millionafter that. Anthropic did not immediately respond to a request for comment. The company says that users of its new tokenizer may see their bills rise by as much as a third compared to the tokenizer it used with its older models. Costs for Anthropic users could go even higher when compared against the latest iteration of OpenAI's o200k tokenizer. Playcode's cross-vendor token comparison finds that for a 2,888 character TypeScript file, Claude's new tokenizer emits 1.73x more tokens than GPT-5.x's tokenizer and 1.32x more than Claude's old tokenizer. These figures differ for different types of code: Rust taps in at 1.58x, JavaScript 1.52x, and Python 1.50x. So if Anthropic's list prices were adjusted to be comparable with OpenAI's GPT-5.x baseline, Playcode suggests Opus 4.8's cost would be $7.50/M input and $37.50/M output instead of the published figure of $5/M and $25/M. The AI app platform notes that a team from marketing platform Ploy this week published an account of a production migration using OpenAI's GPT-5.6 Sol and Anthropic's Opus 4.8. "GPT-5.6 finished pages 2.2× faster, cost 27 percent less, and used about half the output tokens," Ploy claimed. There are other factors that go into calculating AI bills. As we noted recently, costs should be judged in terms of task completion and the impact of model harnesses (e.g. Claude Code, Codex, Pi, OpenCode, etc.) should also be evaluated when attempting to calculate the cost of running AI workloads. ®
Tuesday newspaper round-up: North Sea oil, Anthropic, EV owners
(Sharecast News) - The US government has already paid back tens of billions of dollars in tariffs it collected before the supreme court ruled them illegal, according to budget figures released on Monday. Tariffs - taxes on imported goods - have been a key part of president Donald Trump's game economic plan since he took office again last year. But in February, the supreme court shut down a big chunk of the extra tariffs Trump ordered, forcing the government to return money to the companies that had paid them. - Guardian The UK's North Sea oil industry has made a last-ditch attempt to curry favour with the Labour government by appealing to Andy Burnham's reindustrialisation agenda just days before he is expected to become Britain's next prime minister. Industry lobbyists have written to more than 400 Labour MPs to call on the government's new leaders to allow more oil and gas drilling in UK waters to support homegrown energy and show "a commitment to UK manufacturing, industrial capability and the skilled workforce that has powered the nation for generations". - Guardian The founder of online bank Monzo has become the latest high-profile figure to join Anthropic, the AI company behind the Claude chatbot. Tom Blomfield, who is one of Britain's most successful tech entrepreneurs, will take a leave of absence from his current role at start-up investor Y Combinator to join Anthropic, which recently overtook OpenAI as the world's most valuable AI company. - Telegraph Electric vehicle (EV) owners will be taxed for driving abroad under Labour's pay-per-mile plan. In a consultation response published on Monday, the Government said charging drivers for overseas mileage was proportionate because not doing so would require the use of location data to show where they were - raising privacy concerns. - Telegraph The United Arab Emirates is building another port in an attempt to bypass the Strait of Hormuz, having already expedited the construction of a new oil pipeline. The new port would join an existing facility in Fujairah along the country's eastern coastline and past the tip of the strait that Iran closed to shipping during the war with the United States. - The Times
Anthropic admits Claude has multiple personalities, it is extra warm and friendly with Hindi users
Anthropic says Claude doesn't respond the same in every language, with Hindi users getting warmer and friendlier replies than English speakers. (Image created using AI by Divya Bhati) You might think asking Claude the same question in Hindi or English would only change the language of the reply. But a new study by Anthropic suggests it changes the chatbot's behaviour too. According to the company, Claude expresses different behavioural traits depending on the language users choose. In Hindi, for example, the AI is more likely to respond with humour, politeness and encouragement than it typically does in English. In its latest research, Anthropic analysed more than 309,000 anonymised Claude AI conversations across three Claude models- Sonnet 4.6, Opus 4.6 and Opus 4.7 -- and the 20 most commonly used languages on Claude AI. The conversations mostly involved advice, feedback and opinion-based questions, where there is no single correct answer. Instead of measuring accuracy, the company said it wanted to understand how Claude communicates with users. The results? Anthropic found that Claude came across as warmest when responding in Hindi and Arabic. In contrast, its responses in English and Russian were more analytical and focused on rigour. To make the results easier to compare, Anthropic grouped Claude's behaviour into four broad categories: Deference vs Caution, Warmth vs Rigor, Depth vs Brevity, and Candor vs Execution. According to the company, this helped researchers focus on Claude's behaviour rather than differences in the questions people asked. For Indian users, the biggest takeaway from the study is what Anthropic calls the Warmth vs Rigor axis. The company found that Claude expressed the highest levels of warmth in Hindi and Arabic. In Hindi, the AI was more likely to use polite language, humour and playfulness while affirming users' ideas and work. It also tended to offer reassurance without being asked, adapt its tone to a user's emotional state and encourage users to aim higher. "The largest variation is in the Warmth vs. Rigor axis, with Claude leaning toward expressing warmth-related values most in Arabic and Hindi and rigor-related values most in English and Russian," Anthropic said in its blog post. English, however, painted a different picture. Anthropic found that Claude was more likely to respond with rigour and caution, challenge assumptions, correct details without being prompted and back up its responses with evidence. Overall, the company said the biggest differences between languages lay in how warm or rigorous Claude appeared, while its other behavioural traits remained relatively consistent. The study also found that Claude's behaviour changed depending on the model being used. Sonnet 4.6 came across as the warmest, often using humour, matching a user's tone and offering reassurance without judgement. Opus 4.7, on the other hand, was more analytical. It was more likely to challenge assumptions, explain its reasoning, highlight potential risks and openly acknowledge its own limitations. Opus 4.6 sat somewhere in between, generally sticking closely to a user's request and getting straight to the point. Anthropic notes that the findings do not mean Claude has different beliefs. Instead, the company suggests the results reflected differences in how the AI responds across languages and models. Anthropic added that it is still investigating why these variations exist, but believes the research could help make future AI systems more consistent.
Govt denies reports of delaying OpenAI, Anthropic cybersecurity AI deployment
Report claimed a temporary pause, but the government rejected the claim. The Indian government has asked all ministries to prepare a list of the AI tools they need so these tools can be provided to them. A recent report claimed that the Ministry of Electronics and Information Technology (MeitY) advised ministries not to use cybersecurity AI models made by OpenAI and Anthropic for now. The report did not explain the reason for this advice. Furthermore, the report also claimed that the ban is at the timing of deployment and not on the tools. However, the Indian government has denied the report and said no such halt has been ordered. PIB debunks claim The Press Information Bureau (PIB), which is also the official fact-check agency for the Indian government, recently posted on its official X handle and stated that MeitY had not issued any direction or advisory asking ministries to stop the rollout or use of OpenAI or Anthropic's AI models. Furthermore, the agency also urged the citizens to rely only on official government websites and verified sources for authentic information. Also read: OpenAI asks court to make Elon Musk's xAI pay over Rs 9.5 crore after lawsuit dismissal What the report claimed about OpenAI and Anthropic AI tools According to the report, a department under MeitY had circulated an office memorandum asking ministries not to deploy cybersecurity models developed by OpenAI and Anthropic for the time being. It claimed the development came days after representatives of both companies met officials from several ministries to promote their AI tools. However, the report said it could not independently confirm how many ministries were approached or the level of those meetings. Not only that but it also claims that the Ministry of Finance had written to the department seeking approval to explore the use of agentic AI and OpenAI's GPT 5.5 model for cybersecurity work. And the ministry also outlined the possible applications of AI in the letter, including finding software vulnerabilities, strengthening cyber defence and supporting security operations. Also read: Sam Altman pokes fun at Anthropic's Claude commercial, says he thought it was satire The report also claimed that the department responded with a memorandum declining the proposal for now. However, a source quoted in the report said the response should not be considered a permanent ban. Instead, the concern was about deploying the technology too early rather than blocking its use altogether.
Anthropic is Keeping Free Claude Fable 5 Access Longer Than Planned
Anthropic has extended free access to its flagship Claude Fable 5 AI model for paid subscribers, delaying plans to move the model to a pay-per-use system. Claude Fable 5 was originally scheduled to require usage credits from July 13. However, according to an update on Anthropic's support page, subscribers on the Pro, Max, Team, and Enterprise plans will continue to have access to the model at no additional cost until July 19, 2026. During this period, users can spend up to 50% of their weekly usage limit on Fable 5. Once the promotional period ends, users will either need to purchase usage credits to continue using Claude Fable 5 or switch to another Claude model. Anthropic has also extended the temporary 50% increase to Claude Code usage limits until July 19. Because of its advanced capabilities, Fable 5 consumes usage quota much faster than Anthropic's other Claude models. The extension appears to reflect growing competition in the AI market. OpenAI's GPT-5.6 Sol is included with a standard ChatGPT subscription, offers lower API pricing, and is reported to be more token-efficient. At the same time, Anthropic faces increasing pressure from lower-cost rivals such as GLM 5.2, Meta's Spark 1.1, and Grok 4.5, making it more difficult to rely on Claude Opus 4.8 alone to compete. Claude Fable 5 itself has had an eventful launch. Shortly after its debut in June, Anthropic temporarily withdrew both Claude Fable 5 and the more powerful Claude Mythos 5 after U.S. export controls restricted access to the models over cybersecurity concerns. Following the removal of those restrictions, Anthropic restored Fable 5 globally on July 1 with stronger security safeguards, while Mythos 5 remains available only to approved organizations through the company's Project Glasswing program. Anthropic has said the updated release includes improved cybersecurity classifiers that automatically fall back to Claude Opus 4.8 when certain high-risk requests are detected. The company also stated that it intends to bring Claude Fable 5 back as a standard part of paid subscriptions once computing capacity allows, but for now, the model will eventually move to a usage credit system after the promotional period ends.
Anthropic confirms Claude acts differently depending on your language and which model you pick
A new study shows Claude's isn't nearly as consistent as you might assume. If you've ever felt like Claude gave you a completely different vibe on one day than another, you weren't imagining it. Anthropic just published research confirming that its chatbot's personality shifts depending on which model you pick and which language you type in, and the pattern is consistent enough that it's worth knowing before you ask your next question. The model you pick decides how Claude responds The company analyzed 300,000 real Claude conversations and mapped the chatbot's behavior across four traits, including how cautious versus accommodating it is and how encouraging versus rigorous its tone is. Its findings suggest that you may be talking to a somewhat different version of Claude depending on the model you choose. The split shows up clearly when different models were compared. Anthropic's data shows that Opus 4.7 tends to challenge your thinking and flag problems with your plan unprompted. On the other hand, Sonnet 4.6 leans toward quick, encouraging answers that affirm what you already believe. Neither is objectively better, and which one you should use depends largely on what you're doing. If you're drafting a risky business plan and want real feedback, Opus 4.7 is a better fit, while Sonnet 4.6 is more suited if you only want a quick pass. Your language changes Claude's tone too The data also reveals the language you use matters almost as much as the model. Claude reportedly comes across as warmer in Hindi and Arabic, while it gets more rigorous and skeptical in English and Russian. As such, if you're bilingual and asking Claude for a second opinion, switching languages might get you a genuinely different answer, not just a translated one. Recommended Videos Anthropic is careful to note it doesn't yet know whether these shifts are a problem or just Claude adapting to different cultural norms. Either way, the finding is a useful reminder for anyone using AI for real decisions. Don't assume the first answer you get is the only answer. Trying a different model or language could get you a meaningfully different result.
Anthropic Claude Sonnet 5 vs Sonnet 4.6 vs Opus 4.8: Agentic Coding Benchmarks, API Pricing, and Cost-Performance Tradeoffs Compared
Anthropic just shipped Claude Sonnet 5. They call it its most agentic Sonnet model yet. It plans, drives browsers and terminals, and runs autonomously across long tasks. Sonnet 5 is the default model for Free and Pro plans today. Max, Team, and Enterprise users can select it. It is also live in Claude Code and on the Claude Platform. TL;DR * Sonnet 5 is Anthropic's most agentic mid-tier model, closing much of the gap to Opus 4.8. * Beats Sonnet 4.6 on every published benchmark: 63.2% SWE-bench Pro, 81.2% OSWorld-Verified, 57.4% HLE. * Cheaper to run: $2/$10 per MTok intro pricing through Aug 31, then $3/$15; Opus 4.8 is $5/$25. * Best value at low/medium effort; at xhigh it can cost more than Opus 4.8 for similar quality. * Safer than 4.6, with deliberately low cyber capability -- Opus stays the pick for accuracy-critical work. Claude Sonnet 5 Sonnet sits in the middle of Anthropic's lineup. It is above the cheaper Haiku 4.5 and below the flagship Opus 4.8. Sonnet 5 is an upgrade to Sonnet 4.6, which launched in February 2026. Anthropic frames this release around agentic reliability, not one headline benchmark. In practice, that means longer task chains without losing context. It means better self-correction when a tool call fails. It means steadier behavior across extended sessions inside Claude Code or Cowork. The model exposes effort levels: low, medium, high, and xhigh (extra high). Higher effort spends more tokens on reasoning. That raises both quality and cost. It is important to note that Sonnet 5 uses an updated tokenizer, the same one introduced with Opus 4.7. The same text can map to roughly 1.0 to 1.35 times more tokens. Interactive Explainer Benchmark Anthropic team published a benchmark table comparing Sonnet 5, Sonnet 4.6, and Opus 4.8. Sonnet 5 beats its predecessor in every tested category. It closes much of the gap to Opus 4.8. On agentic coding (SWE-bench Pro), Sonnet 5 scores 63.2%. Sonnet 4.6 scored 58.1%. Opus 4.8 still leads at 69.2%. On computer use (OSWorld-Verified), Sonnet 5 posts 81.2% against Sonnet 4.6's 78.5%. On Terminal-Bench 2.1, it reaches 80.4% versus 67.0%. On Humanity's Last Exam with tools, Sonnet 5 hits 57.4%. That nearly matches Opus 4.8 at 57.9%. There is one place where Sonnet 5 edges ahead. On the GDPval-AA v2 knowledge-work benchmark, it scores 1,618 against Opus 4.8's 1,615. Effort Levels: Where the Real Tradeoff Lives The cost-performance story is the most important part for developers. Sonnet 5 is a strict improvement over Sonnet 4.6 across every effort level. The clearest value appears at low and medium effort. At those levels, Sonnet 5 delivers quality that earlier Sonnet pricing could not buy. Opus 4.8 remains the accuracy leader at the top of the range. A practical routing policy follows from this. Send most agentic coding, tool use, and knowledge work to Sonnet 5. Reserve Opus 4.8 for accuracy-critical tasks. Keep Haiku 4.5 for high-volume, latency-sensitive calls. Use Cases: Where Sonnet 5 Fits Early access partners described concrete workflows. Their reports map to common engineering jobs. * Multi-step software engineering: One tester asked Sonnet 5 to investigate a bug. It wrote a reproducing test, implemented the fix, then confirmed the bug returned without the change. It did this in a single pass. * Brownfield debugging: Another partner ran it on hard pull requests. The model traced failures to their root causes. It shipped durable fixes rather than symptom patches. * Business automation: Zapier handed it a two-part job. It updated Salesforce account tiers, then sent a launch email to enterprise contacts. It finished the task end to end. * Computer-use agents: Pace runs insurance workflows like submission intake and loss runs. Its agents act on the operational systems teams already use. * Data exploration: ClickHouse agents query live data and produce insights on the fly. Faster reasoning means faster time-to-insight for analysts. Comparison Table Sonnet 5's introductory pricing runs through August 31, 2026. Standard pricing of $3/$15 begins after that date. Standard prompt caching (cache reads at 0.1x input) and the 50% Batch API discount also apply. Per token, Sonnet 5 undercuts GPT-5.5 and Gemini 3.1 Pro, but costs more than Gemini 3.5 Flash. Anthropic lists a 1M-token context window for Sonnet 5 in its launch post. It does not publish context figures for the other models here. Coding Example: Calling Sonnet 5 The API call mirrors any other Anthropic model. You change the model string to . Strengths and Weaknesses Strengths: * Improves on Sonnet 4.6 in every benchmark category Anthropic tested * Near-Opus 4.8 quality on several evaluations, at lower per-token prices * Edges Opus 4.8 on the GDPval-AA v2 knowledge-work benchmark * Lower hallucination, sycophancy, and undesirable-behavior rates than Sonnet 4.6 * Drop-in API change: you only swap the model string Weaknesses: * Opus 4.8 still wins on the hardest accuracy-critical tasks * At xhigh effort, cost can exceed Opus 4.8 at similar quality * The new tokenizer can raise token counts by up to 1.35 times * Cyber capability is intentionally low; use Opus for sanctioned cyber work * Standard pricing of $3/$15 arrives after August 31, 2026 Community Reaction Check out the Technical details.
