In one minute

GitHub says Claude Haiku 5.5, Anthropic’s lightweight model, is now generally available in GitHub Copilot.

The changelog lists availability for Copilot Pro, Pro+, Max, Business, and Enterprise users, with a gradual rollout across the model picker in Visual Studio Code, Visual Studio, Copilot CLI, GitHub Copilot cloud agent, the Copilot app, github.com, GitHub Mobile, JetBrains IDEs, Xcode, and Eclipse. Billing is usage-based at provider list pricing. GitHub describes the model as intended for fast, high-volume work such as subagents, quick edits, and terminal tasks. Its claim that early testing found Haiku 5.5 matched Claude Sonnet 5 on many coding tasks is an early-test report, not an independent benchmark. Business and Enterprise administrators can manage access through Copilot’s model policy settings.
