Anthropic debuts Claude Opus 5 with feature that lets users toggle between cost and capability

Anthropic released Claude Opus 5, an AI model with a toggle feature allowing users to balance cost and capability by adjusting computational effort. The model addresses enterprise concerns about AI expenses and follows Anthropic's recent release of three other models, including Fable 5, which faced temporary export controls due to security risks. Opus 5 is positioned as a cost-effective alternative to Fable 5 while maintaining similar capabilities.
