GPT-5.5 is generally available for GitHub Copilot

Source: GitHub Changelog

Overview

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 tasks and resolves real‑world coding challenges previous GPT models couldn’t.

Note: 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:

Rollout will be gradual. Check back soon if you don’t see it yet.
