What is Claude Opus 5.5?
Claude Opus 5.5 is Anthropic’s flagship everyday model, released on 22 September 2026 as the first model of the Claude 5.5 family. Secondo Anthropic, it performs at the level of Claude Fable 5.1 on most work and generates output more than 30% faster than Opus 5.
It is also cheaper than Opus 5: $4 per million input tokens and $20 per million output (Opus 5: $5 / $25), with cache reads at $0.20 and cache writes at $5 per million. An optional Fast mode is billed at $8 / $40. Anthropic raised the five-hour usage limits on its Pro, Max, Team and seat-based Enterprise plans alongside the launch, and says Claude Sonnet 5.5 and Haiku 5.5 follow in the coming weeks.

Can I run Claude Opus 5.5 locally?
No. Claude Opus 5.5 is a closed, API-only model — the weights are not released, so it cannot be self-hosted.
Why does Claude Opus 5.5 charge more for output than input?
Output tokens are generated one at a time and cannot be batched the way a prompt can, so they cost the provider more to serve. Claude Opus 5.5 charges 5× more for output, which is why prompt-heavy workloads are far cheaper to run than generation-heavy ones.
