Anthropic unveils Claude Opus 4.7, 2nd most powerful after Mythos

Anthropic (ANTHRO) unveiled its latest AI model Claude Opus 4.7, which is now generally available.

The company said that Opus 4.7 is a notable improvement on Opus 4.6 in advanced software engineering, with particular gains on the most difficult tasks.

Opus 4.7 offers notable gains on difficult engineering tasks, processes complex, long-running assignments with rigor, displays precise instruction-following, and better verifies its outputs compared to Opus 4.6.

Claude Mythos Preview's advanced capabilities in coding and cybersecurity have led financial authorities and Wall Street leaders to assess new threats and risks its deployment may introduce.

Anthropic is involved in a legal dispute due to being labeled a supply chain risk, resulting in blacklisting and specific contractual demands by U.S. government agencies, which Anthropic has contested in court.
