Additional context

Hi there

Can you please let me know what the input/output limits are for models access through github copilot CLI?

I haven't been able to find this information.

I'm keen to understand the respective input/output context window limits for sonnet 4.5 and GPT-5.

No worries if you can't disclose exact information, if you could provide some lower bound, that would be extremely useful.

Thank you so much Dean
