We have updated our available model selection for Copilot Chat on the web to deliver more consistent, high-quality responses.
What’s changed
While model choice is valuable, we are limiting the list of available models on github.com so that we can consistently ensure reliable responses.
All Gemini models and several other models (e.g., GPT-5.2 Codex and GPT-5.4 nano) have been removed from Copilot Chat on the web.
OpenAI and Claude models across price points are still available across Copilot plans.
