encountered the same when calling with vercel AI SDK streamText() and there is no way to remove temperature, it defaults to 0 which then triggers OpenAI:

exception. requestBodyValues {
model: ‘gpt-4o-mini-search-preview’,
logit_bias: undefined,
logprobs: undefined,
top_logprobs: undefined,
user: undefined,
parallel_tool_calls: undefined,
max_tokens: undefined,
temperature: 0,

same here:
I tried to find any reference in the OpenAI API documentation about these parameters not being used, accepted, … with the new …-search models

But nothing documented, yet?!

4

can someone point us to an openAI doc or API reference page that explicitly hints which params are allowed in completions API for the new *-search models - and which not?

Thank you!

Hi. You can view the availability of the parameters in the Playground.

Ran into the same issue with generateObject. I simply created a new method called generateObjectWithSearch calling OpenAI directly for now.
