How can a developer prevent an AI model from making too many API calls at once?

An AI model's API calls must be spaced out. Submitting many calls at the same time can cause errors. This is true even if the total number of calls per second is low.

The rule

An AI model's API calls must be spaced out.

Submitting many calls at the same time can cause errors. This is true even if the total number of calls per second is low.

A developer must space out API calls. Submit each call with a delay of at least 250 milliseconds. This makes the calls arrive smoothly, not all at once. If an API call fails, a developer must not retry it immediately. Waiting for at least one second is important. Retrying too fast can make the problem worse and lead to longer bans. When processing many items in groups, a developer must pause between groups. A pause of 2 to 4 seconds between groups helps reset the API's rate limit window. This prevents new groups from starting with a burst of calls.

A developer writes code to send 10 requests to an AI model. The code uses a loop that sends all requests in less than 5 milliseconds. The AI model's API sees this as a sudden burst of traffic. The API returns an error message saying too many requests were made. The developer changes the code to wait 250 milliseconds before each request. This spreads the 10 requests over 2.5 seconds. The API now accepts all requests without errors.

How should a developer manage calls to an external AI model?

A developer must use the project's central coordinator for all calls to an external AI model. This coordinator applies several checks before an AI model call can proceed.

How should a developer handle API policies and intellectual property concerns when starting a new session?

A developer must read specific API policy files before writing any code that makes external API calls. This prevents common mistakes.

How can a developer prevent an AI model from truncating its output when creating large structured data?

A developer must estimate the token count of the AI model's output before making an API call. If the estimated output is more than 6000 tokens, the developer should split the request.

What happens when a user sends too many requests to a system?

When a user sends too many requests, the system stops all new requests from that user. This is called a 'hard stop'.

What to remember

An AI model's API calls must be spaced out. Submitting many calls at the same time can cause errors. This is true even if the total number of calls per second is low.
