‘Mythos-class model’ to be generally available within weeks; U.S. Anthropic releases ‘Opus 4.8’

Anthropic plans to make its Mythos-class model available to all customers within weeks, after adding more safety measures.

The model had previously been limited to select partners for defensive security use.

Anthropic also released Claude Opus 4.8, saying it improves coding, reasoning, agent performance, honesty, and code review reliability.

Pricing for Opus 4.8 remains unchanged.
