Source: Anthropic: Introducing Claude Opus 4.7

Anthropic made Claude Opus 4.7 generally available, saying it improves on Opus 4.6 in advanced software engineering, especially the hardest tasks, at the same $5 and $25 per million token pricing. Anthropic said it is less broadly capable than Claude Mythos Preview, which it was keeping to Project Glasswing partners.

Why it matters

Developers got Anthropic’s strongest generally available model nine days after it held back Mythos Preview for cyber defenders only.
