DeepSeek v3.2 long reasoning timeout on Vercel AI Gateway

AI SDK
1

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. That will let us all work together from the same code to figure out what’s going wrong.
