OpenAI has just released their new API:
It now has built-in search functionality that can be used with a specific model gpt-4o-search-preview
So I’m already creating this feature request to add their search model to n8n 
Any tip in how config this one? I just keep getting error messages with this model.
Error Message 1:
Model incompatible request arguments supplied: frequency_penalty, n, presence_penalty, temperature, top_p
Error Message 2:
Somthing about this model doesn’t support tools (like data bases and so, but I’m not using any tool, just parsers)
i have the same issue - error :“Model incompatible request arguments supplied: frequency_penalty, n, presence_penalty, temperature, top_p”
similar request for search grounding support of the Gemini model here, it has been sitting still for the past 4 months, let´s push this to the top! Update Google Gemini Chat Model node to support new grounding feature - #3 by Devilish
