Anthropic Launches Claude Opus 5.5 with 60% Price Reduction

Anthropic has released Claude Opus 5.5, the first model in its new 5.5 family. The model matches the performance of the flagship Claude Fable 5.1 while costing 20% less than the previous Opus 5 and 60% less than the Fable 5.1. As the most advanced model in the current lineup, it is positioned as a more cost-effective option for users. This release follows CEO Dario Amodei's recent public call for the AI industry to slow down the pace of capability improvements to prioritize safety testing.
