[Bug]: Issue switching model for an assistant

[odoremieux]

Description

When we switch model from a non reasoning (gpt-4o-mini) to a reasoning model (o1), it throw an exception Unsupported parameter: 'temperature', even so temperature is not part of the array we give to client->assistants()->modify . Without deleting the assistant, is there a workaround?

Steps To Reproduce

Switch the model for an existing assistant between non reasoning (gpt-4o-mini) to a reasoning model (o1)

OpenAI PHP Client Version

v0.10.3

PHP Version

I couldn't replicate this. I started with an assistant and changed it back n forth. I quickly learned I had to send the valid reasoning_effort of null or non-null depending if a reasoning model. However, it worked once I did that as I went back n forth.

        $result = $client->assistants()->modify("asst_xxx", [
            'model' => 'gpt-4o-mini',
            'reasoning_effort' => null,
        ]);

        // changing back
        $result = $client->assistants()->modify("asst_6xxx", [
            'model' => 'o1',
            'reasoning_effort' => 'low'
        ]);

Able to give me a little sample that still replicates an issue?
