GitHub has announced that Anthropic's latest model, Claude Opus 4.5, is rolling out to GitHub Copilot users in a phased public beta. According to the official introduction, in early tests, the model achieved better results on internal coding benchmarks while cutting token usage by about half, making it especially suitable for accelerating development in professional environments and playing a role in complex workflows such as code migration and code refactoring.
Currently, Claude Opus 4.5 is available to Copilot Pro, Pro+, Business, and Enterprise paid users, and is available in Copilot Chat in VS Code (including Agent, Plan, Ask, and Edit modes), Copilot Chat on github.com, GitHub Mobile, and Copilot CLI in the Enabled via the Model Selector. During this period, a limited-time 1x premium request multiplier offer will be provided until December 5, 2025, and the GitHub documentation shows that the multiplier will be increased to 3x after the discount ends, and users need to arrange the use reasonably according to their own premium request quota.
In terms of enablement, Enterprise and Business plans require administrators to turn on the Claude Opus 4.5 policy in Copilot settings, while Pro and Pro+ users can manually select models and complete one-time confirmations in VS Code. GitHub also said that during the promotion period, Claude Opus 4.5 will gradually become the default model when the Copilot coding agent is enabled, but due to the gradual release, some users may have to wait a while to see the option.
