[400] Unknown parameter: 'modalities'. for GPT-5

[Andrii_Daniv]

Hi there! Getting this error:
[400] Unknown parameter: ‘modalities’. for GPT-5 API. The module works on previous versions of GPT, but after switching to GPT-5, I started getting that error.

Same here. If checking for a solution it is stated, that the new model is available in the module but not yet officially supported by Make.com. I hope, that this is fixed really quick

I got the same error. Waiting for Make.com to add GPT-5 support

Hi, while we look into why it is not working on the “Create a completion (prompt)” module – you can leverage GPT-5 on the “OpenAI: Create a model response” module - -this is technically the preferred module (and related API from OpenAI) going forward (and has a ton of ridiculously powerful features).

Thanks a lot! I don’t know how I missed it. It’s super useful.

You can use it, just choose latest model in gpt-5, the plain gpt-5 gives error inclusive with API.

Worked with “OpenAI: Create a model response” module - Thanks

I’m getting the same errors and when I go to the dropdown to select Open:AI Create a model response I get. Can someone provide a few screenshots to help me understand what I need to do to. Thank you
