Anthropic’s Claude Opus 4.8 Boosts Collaboration and Speed
Anthropic released Claude Opus 4.8, touting sharper judgment, greater honesty about progress, and longer independent work; early testers report fewer unsupported claims. The upgrade brings notable performance gains in coding, multidisciplinary reasoning with tools, and financial analysis, with fast mode roughly 2.5x faster and pricing unchanged from Opus 4.7. It also adds Claude Code enhancements with higher rate limits for extra/max modes. Three additional updates accompany the launch: Dynamic workflows for handling very large tasks, an effort-control option in Claude AI and Cowork, and Messages API updates; a Mythos-class model is expected for all customers soon. Global availability starts today.
