concepts

Rate limiting is a mechanism used to control the number of requests a user or application can make in a given time period. {% data variables.product.github %} uses rate limits to ensure everyone has fair access to {% data variables.product.prodname_copilot %} and to protect against abuse.

When you hit a rate limit, you may temporarily lose access to certain {% data variables.product.prodname_copilot %} features or models, and you’ll see an error message informing you that you’ve been rate limited.

Why does {% data variables.product.github %} use rate limits?

{% data variables.product.github %} enforces rate limits for several reasons.

Capacity: There is a limited amount of computing power available to serve all {% data variables.product.prodname_copilot_short %} users. Rate limiting helps prevent the system from being overloaded.
High usage: Popular features and models may receive bursts of requests. Rate limits ensure no single user or group can monopolize these resources.
Fairness: Rate limits ensure that all users have equitable access to {% data variables.product.prodname_copilot_short %}.
Abuse mitigation: Without rate limits, malicious actors could exploit {% data variables.product.prodname_copilot_short %}, leading to degraded service for everyone or even denial of service.

What to do if you are rate limited

If you receive a rate limit error when using {% data variables.product.prodname_copilot_short %}, you should:

Wait and try again. Rate limits are temporary. Often, waiting a short period and trying again resolves the issue.
Check your usage. If you’re making frequent or automated requests (for example, rapid-fire completions or large-scale usage), consider adjusting your usage pattern.
Change your model. Preview models may have stricter rate limits due to limited capacity.
Contact Support. If you’re repeatedly rate limited and believe it’s impacting legitimate use, contact {% data variables.contact.contact_support_page %} for assistance.

[!NOTE] Service-level rate limits should not affect typical {% data variables.product.prodname_copilot_short %} usage. However, if you’re heavily using preview models, you may encounter rate limits more frequently.
