Tool calling with o3+o4-mini

[aayush-trivedi]

hey so I've been having an issue with the o3 and o4-mini models.

Here's the issue.
So we have a unified api through which users can talk to basically any bot they want to talk to.
We also manage tool use from this api. The interesting thing though is that o3 and o4-mini actually work quite well with the current simulated tools (only like 2 params and was using this to test some stuff).

But the moment I go to the websearchtool and specifically add parameters as I start to transition to the real web search api call I'm not able to use o3 and o4-mini. They simply return empty strings.

Which is weird because. They work with the simulated calls just fine!

Has anyone else had any similar issues? I read something about how making reasoningSummary: 'detailed' meant I was using the responses api which doesn't work the the AI SDK's tool use but not so sure about that.

Do you have a minimal reproducible example?
