Anthropic releases Claude Opus 5.5 with faster, cheaper performance

By PulseAugur Editorial · [1 sources] ·

Anthropic has released Claude Opus 5.5, the first model in the Claude 5.5 family, on September 22, 2026. This model is designed for demanding, long-running tasks such as agentic coding and multi-file document analysis, capable of processing both text and images. Compared to its predecessor, Opus 5.5 offers a significant price reduction and performance increase, with typical workloads running approximately 40% cheaper and over 30% faster. The new model also introduces five effort levels to control the depth of its thinking, impacting cost and thoroughness, and requires adjustments for API users who previously worked with Opus 5. AI

IMPACT Sets new SOTA on agentic coding and multi-file analysis, offering significant cost and speed improvements over previous versions.
