AISummary
Anthropic's lightweight Claude Haiku 5.5 is now generally available in GitHub Copilot for fast, high-volume tasks such as subagents, quick edits, and terminal work.
In early testing, it matched Claude Sonnet 5 on many coding tasks while using significantly fewer tokens and steps.
The model is billed at provider list pricing under usage-based billing and is available to Copilot Pro, Pro+, Max, Business, and Enterprise users.
