Add OpenAI o1 to copilot

[lyc280705]

OpenAI o1 uses chain of thought. It has large improvement in coding. I can't wait to see what will happen if you can bring this model to copilot.

Is there any news on when it will be implemented?

No updates yet, but it's something actively being investigated.

The O1 API has some limitations compared to other models such as:

• No system message
• No tool calling
• No support for parameters such as temperature
• No streaming of responses

These limitations of course present unique implementation challenges that we must work through.

We already have news about the implementation and a waiting list: Try out OpenAI o1 in GitHub Copilot and Models
