226229### Fast mode rate limits
227230
228When you use [fast mode](https://platform.claude.com/docs/en/build-with-claude/fast-mode) with `speed: "fast"` on Claude Opus 5.5, Claude Opus 5, or Claude Opus 4.8, dedicated rate limits apply. They are separate from standard rate limits. Claude Opus 5.5 has a default fast mode rate limit in the Start, Build, and Scale tiers, so you don’t need to request access to use fast mode with it. Organizations in the Evaluation tier can use fast mode with Claude Opus 5.5 once they move to the Start, Build, or Scale tier. Fast mode for Claude Opus 5 and Claude Opus 4.8 is in research preview. To see your fast mode rate limits, go to the [Rate limits](https://platform.claude.com/usage/limits) page in the Claude Console. When you exceed your fast mode rate limits, the API returns a `429` error with a `retry-after` header.
