129129OTPM rate limits are evaluated in real time as output tokens are produced, counting only the actual tokens generated. The `max_tokens` parameter does not factor into OTPM rate limit calculations, so there is no rate limit downside to setting a higher `max_tokens` value.

131Each row in the following tables has its own RPM, ITPM, and OTPM limits. Some rows cover several models that share one limit; see the notes under the tables. You can check your current rate limits and behavior on the [Rate limits](https://platform.claude.com/usage/limits) page in the Claude Console, or read the configured limits programmatically with the [Rate Limits API](https://platform.claude.com/docs/en/manage-claude/rate-limits-api).
