# DeepSeek v3.2 long reasoning timeout on Vercel AI Gateway

Hi all, I’m using **Vercel AI Gateway** with **DeepSeek v3.2** for long “reasoning/thinking” tasks and I’m consistently hitting a hard cutoff:

* **Non-streaming** requests get terminated at \~**340s**

* **Streaming** runs longer but still gets cut off at \~**790s** (stream disconnects mid-output)

Has anyone seen this? What’s the usual way to fix or work around it (gateway timeout settings, async job + polling, splitting the task, etc.)?

Thanks!

Hi @hazlettmcdonalds459, welcome to the Vercel Community!

Is it because your Vercel Functions are timing out? Or is it happening locally as well?

Please share your public repo or a [minimal reproducible example](https://vercel.com/guides/creating-a-minimal-reproducible-example). That will let us all work together from the same code to figure out what’s going wrong.
