228231### Fast mode rate limits
229232
230When using [fast mode](https://platform.claude.com/docs/en/build-with-claude/fast-mode) (research preview) with `speed: "fast"` on Claude Opus 5 or Opus 4.8, dedicated rate limits apply that are separate from standard Opus rate limits. When fast mode rate limits are exceeded, the API returns a `429` error with a `retry-after` header. Fast mode is not available on Claude Opus 4.7 (requests return an error) or Claude Opus 4.6 (requests to `claude-opus-4-6` with `speed: "fast"` run at standard speed). See [Fast mode](https://platform.claude.com/docs/en/build-with-claude/fast-mode#supported-models).
