Does magentic support o1 and o1-mini models?

[Lawouach]

Hi,

I was trying to use these models today while generating structured output with OpenaiChatModel. But, I ran into issues as these models do not support the same range of parameters as older models like gpt-4. Thus magentic breaks quite heavily.

Notably, the o1 models don't:

• support to set max_tokens (aside from setting it to 1)
• allow the parallel_tool_calls parameter
• support tools

Right now all structured output in magentic uses tool calls which these models don't support. o1 (but not o1-mini I think) supports openai's structured outputs, which magentic should really be using in the case where a single structured output is desired (no union in return type and no functions provided). Issue for that is #295 Apart from that, I think we just have to wait for openai to add support for tools. The parallel_tool_calls and max_tokens parameters could be optionally omitted.
