Claude Haiku 5.5, Anthropic's newest lightweight model for fast, high-volume work like subagents, quick edits, and terminal tasks, is now generally available in GitHub Copilot.
In early testing it matched Claude Sonnet 5 on many coding tasks while using significantly fewer tokens and steps. It's available to Copilot Pro, Pro+, Max, Business, and Enterprise users across VS Code, Visual Studio, Copilot CLI, JetBrains IDEs, Xcode, Eclipse, GitHub Mobile, and more, billed at provider list pricing. Enterprise admins can manage access via model policy; rollout is gradual.
