Thanks for the clarification! That makes sense about the TPM limit.
At this point I’m no longer running into TPM issues since my OpenAI tier has been upgraded, but now I’ve hit a different problem:
-
Until yesterday, Deep Research was running fine with o3-deep-research.
-
Suddenly, it no longer produces any output. Zap history shows no errors, just “delayed.”
-
If I use o4-mini-deep-research with
max_output_tokensset to ~70,000, it works as expected. -
But with o3-deep-research, nothing comes back at all — no error messages, just delayed indefinitely.
Has anyone else run into this behavior with o3-deep-research on Zapier? Or does anyone know of a workaround / solution?
