Using model "o3-mini" from openAI. This gives the following error:

API error: Error code: 400 - {'error': {'message': "Unsupported parameter: 'max_tokens' is not supported with this model. Use 'max_completion_tokens' instead.", 'type': 'invalid_request_error', 'param': 'max_tokens', 'code': 'unsupported_parameter'}}

Please use max_completion_tokens in the API request.

Maybe you can provide your config.toml without sensitive information for better understanding your situation.

Sure, just do this:

[llm]
model = "o3-mini"
base_url = "https://api.openai.com/v1"
api_key = "sk-...."
max_tokens = 4096
temperature = 0.0

[llm.vision]
model = "o3-mini"
base_url = "https://api.openai.com/v1"
api_key = "sk-...."

Btw, I've already implemented a fix on my own machine, so will also make a PR that fixes this when o3-mini is used. This is also required since the o3-mini model doesn't have a "temperature" parameter.
