Anthropic rolls out Claude Opus 4.7, an AI model that is 'broadly less capable' than Mythos

Anthropic on Thursday announced a new artificial intelligence model, Claude Opus 4.7, which the company said is an improvement over past models but is “broadly less capable” than its most recent offering, Claude Mythos Preview.

Claude Mythos Preview is Anthropic’s most powerful AI model that excels at identifying weaknesses and security flaws within software. The company announced the model earlier this month and said it would roll out to a select group of companies as part of a new cybersecurity initiative called Project Glasswing.

Anthropic said that while Claude Opus 4.7 is not as powerful as Claude Mythos Preview, it still shows improvements over Claude Opus 4.6, which the company announced in February.

“We are releasing Opus 4.7 with safeguards that automatically detect and block requests that indicate prohibited or high-risk cybersecurity uses,” Anthropic said in a release. “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.”
