Anthropic ships Claude Opus 4.7 as Mythos looms

Anthropic may be holding back Mythos, but it doesn't want its users to go hungry.

On Thursday, the company released Opus 4.7, the latest addition to the highest tier of its Claude model family. Anthropic said the model offers "notable improvement" in software engineering tasks compared to Opus 4.6, allowing users to "hand off their hardest coding work" and long-running tasks with greater confidence.

Anthropic also says Opus 4.7 can see images with substantially better resolution, produce more "tasteful and creative" outputs for professional tasks and produce higher-quality documents, slides and designs.

The company tested the model in preview with several companies, with several reporting gains in efficiency, reliability and speed. In a statement, Box's Head of AI, Yashodha Bhavnani, told The Deep View that the model was able to do significantly more with less, performing fewer tool calls and offering lower latency for "enhancements that will help enterprises move faster and scale more affordably."

Along with quelling the appetite of customers chomping at the bit to try Mythos, Anthropic's Opus 4.7 serves as a testbed for the cyber safeguards it is building as part of Project Glasswing, the company said. This model includes safeguards that automatically detect and block requests that signal prohibited or risky cybersecurity issues.

"What we learn from the real-world deployment of these safeguards will help us work towards our eventual goal of a broad release of Mythos-class models," Anthropic said in the announcement.

Anthropic has gotten the industry riled up with all of the chatter around Mythos. As the company figures out what to do with this extremely powerful (and compute-hungry) model, its archrival OpenAI has released GPT-5.4-Cyber and made it available to a wider audience than Mythos. While Anthropic says it intends to use Opus 4.7 to work up to Mythos, the company may be feeling the pressure to ship, especially as some users report switching to OpenAI's Codex as they run up against Claude's rapidly depleting quotas and uptime issues. But as users await Mythos, Opus 4.7 might feel like a consolation prize.
