Anthropic Releases Opus 5.5 With Lower Prices

Anthropic released Claude Opus 5.5 on Tuesday, claiming state-of-the-art coding and knowledge work performance. Output tokens cost $20 per million, down from $25, and the model runs over 30% faster. It outperforms the larger Fable model on many benchmarks. Sonnet 5.5 and Haiku 5.5 will follow in coming weeks. The release is Anthropic's first since CEO Dario Amodei embraced pacing frontier AI capabilities.
