Adding GPT-5 series models as built-in models, fresh out of the oven! Supports the new parameters reasoning_effort and verbosity. To see them, you may have to click "Refresh Builtin Models" under your chat model table in Copilot settings.

You can also add openrouter GPT-5 models such as openai/gpt-5-chat as a Custom Model with the OpenRouter provider.

This is an unscheduled release to add GPT-5. Copilot v3 is under construction and will be released officially very soon, stay tuned!
