Inference requests, such as chat completions, messages, and embeddings, can be up to 32 MiB on every API format. A larger request gets `ERR_NGROK_AI_GATEWAY_REQUEST_BODY_TOO_LONG` right away, so it never reaches a provider.

Most requests are far below the limit. If you hit it, trim long conversation history or large embedded documents.

## Get started

1. Check the [error code reference](https://ngrok.com/docs/ai-gateway/reference/error-codes) for the full error.
2. If you see it, shorten the request and send it again.
