Unknown parameter: 'data_source.sampling_params.text.verbosity' error in eval

API Bugs
1

Hi everyone,

I’m running into the same issue described in the “OpenAI Evals bug: Unknown Parameter” thread, which appears to have been closed without a fix.

When I run my eval I have a error : Unknown parameter: ‘data_source.sampling_params.text.verbosity’.

I’ve tried reproducing the setup as cleanly as possible based on the suggestions in the thread, but I’m still getting the same error.

For context, I followed this setup :

  • Created a new eval from scratch in the OpenAI Platform dashboard

  • Uploaded a CSV file as test data

  • Enabled “Generate new responses”

  • Only used text columns (no images)

  • Did not select “Import as responses”

  • Used a simple developer/user prompt

  • Added a semantic similarity grader

However, the issue still persists, and I haven’t been able to identify where verbosity is being injected from or how to disable it.

Has anyone found a workaround or fix for this?

Thanks a lot in advance :folded_hands:
