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.
