A slow reasoning model can think for a long time before it writes a word, and then write a lot of words. Streams now keep going for up to 15 minutes.

The per-request timeout applies only until the first byte arrives. After that, a stream stops if the provider goes quiet for 30 seconds or the total timeout runs out. If you set your own total timeout, it still applies.

## Get started

1. Send a request with `stream: true` through `https://gateway.ngrok.ai`.
2. To change the limits, see [streaming responses](https://ngrok.com/docs/ai-gateway/guides/account-settings#streaming-responses) in the account settings guide.
