8 **[Claude Platform on AWS](https://platform.claude.com/docs/en/build-with-claude/claude-platform-on-aws):** The rate limits on this page apply to Claude Platform on AWS, but billing and limit management differ. Billing is through AWS Marketplace (not Anthropic credit purchases). Organizations on Claude Platform on AWS are placed on the Start tier and can move to a higher tier automatically as they build a history of paid AWS Marketplace invoices. To request higher limits, contact your Anthropic account representative or [Anthropic support](https://support.claude.com); the **Request rate limit increase** flow is not available. Per-workspace rate limit configuration and [fast mode](https://platform.claude.com/docs/en/build-with-claude/fast-mode) are not available on Claude Platform on AWS.

1111There are two types of limits:
from line 20
2020* Limits are designed to prevent API abuse, while minimizing impact on common customer usage patterns.
2121* Limits are defined by **usage tier**. Organizations are placed on a tier automatically based on usage history and account standing and can move to a higher tier over time as they use the API.
2222* New organizations and organizations with limited usage history may start in the Evaluation tier, with limits below the standard limits shown on this page while account history is established. These starting limits are part of how Anthropic prevents fraud and abuse, and they increase automatically as your organization builds usage history.
23* Limits are set at the organization level. You can see your organization's tier and current limits on the [Rate limits](https://platform.claude.com/settings/limits) page in the [Claude Console](https://platform.claude.com/).

2424* You might hit rate limits over shorter time intervals. For instance, a rate of 60 requests per minute (RPM) might be enforced as 1 request per second. Short bursts of requests can exceed the limit and trigger rate limit errors.
2525* The following limits are the standard limits for each tier. If you need higher limits, see [Requesting higher limits](https://platform.claude.com/docs/en/api/rate-limits#requesting-higher-limits).
2626* The API uses the [token bucket algorithm](https://en.wikipedia.org/wiki/Token_bucket) to do rate limiting. This means that your capacity is continuously replenished up to your maximum limit, rather than being reset at fixed intervals.

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.

131Rate limits are applied separately for each model; therefore you can use different models up to their respective limits simultaneously. You can check your current rate limits and behavior on the [Rate limits](https://platform.claude.com/settings/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).
