GPT-5.5 is generally available for GitHub Copilot
GPT-5.5, OpenAI’s latest GPT model, is now rolling out on GitHub Copilot. In our early testing, GPT-5.5 delivers its strongest performance on complex, multi-step agentic coding task and resolves real-world coding challenges previous GPT models couldn’t.
Note that this model is launching with a 7.5× premium request multiplier as part of promotional pricing.
GPT-5.5 will be available to Copilot Pro+, Copilot Business, and Copilot Enterprise users.
You’ll be able to select the model in the model picker in:
Visual Studio Code
Visual Studio
Copilot CLI
GitHub Copilot cloud agent
github.com
GitHub Mobile iOS and Android
JetBrains
Xcode
Eclipse
Rollout will be gradual. Check back soon if you don’t see it yet.
Copilot Enterprise and Copilot Business plan administrators must enable the GPT-5.5 policy in Copilot settings.
