Claude Haiku 5.5 在 GitHub Copilot 中正式可用

Claude Haiku 5.5, Anthropic’s newest lightweight model, is now generally available in GitHub Copilot. It is designed for fast, high-volume work like subagents, quick edits, and terminal tasks. In early testing, Haiku 5.5 matched Claude Sonnet 5 on many coding tasks while using significantly fewer tokens and steps.

This model is billed at provider list pricing under usage-based billing. See Models and pricing for GitHub Copilot for details.
