Receiving "Unsupported parameter: 'logit_bias'" Error with OpenAI O1 Model

Hi everyone,

I’m currently using the “Create a Completion” module in Make.com (formerly Integromat) with the OpenAI O1 model and encountering the following error message:

[400] Unsupported parameter: 'logit_bias' is not supported with this model.

I’ve reviewed my scenario settings and I don’t see any direct reference to logit_bias in the configuration. Yet, the request fails with this error. According to various discussions and documentation, this error suggests that the O1 model does not support the logit_bias parameter.

Here’s what I’ve gathered so far:

  • Model Compatibility: Not all OpenAI models support logit_bias, and newer models (like O1) may not allow it.
  • Platform-Specific Behavior: Some third-party tools or integrations might implicitly include logit_bias when calling the API, even if it’s not visible in the UI.
  • Azure OpenAI & API Versions: Users on Azure OpenAI have reported similar issues, indicating that certain models which previously supported logit_bias no longer do so. Changing the API version or model can sometimes resolve this.

Questions for the Community:

  1. Has anyone else encountered this error specifically when using the O1 model in Make.com’s OpenAI integration?
  2. Are there any known workarounds, such as switching to a different model or adjusting some hidden setting?
  3. Has anyone successfully disabled or removed logit_bias from Make.com’s OpenAI call parameters to prevent this error?

I’d appreciate any insights, tips, or guidance on how to resolve or work around this issue. Thanks in advance!

I have the same problem, same error. RuntimeError: [400] Unsupported parameter: ‘logit_bias’.
The error suggests that logit_bias is automatically being included in the request, even though it is not visible in the UI configuration.
