Anthropic releases a new Opus model amid Mythos Preview buzz - The Verge

Anthropic has released Claude Opus 4.7, a new version of its Opus model. The company states this release does not advance its 'capability frontier' compared to the unreleased Claude Mythos Preview. The model includes additional cybersecurity safeguards.

Anthropic indicated that findings from Opus 4.7's deployment will help work toward a broader release of Mythos-class models. The release follows recent announcements about Anthropic's expansion plans, including a new London office space for 800 people.

The company's approach focuses on incremental releases with enhanced safety features rather than pushing capability boundaries. This strategy aligns with Anthropic's stated emphasis on developing AI safely and responsibly.
