Anthropic's Claude Opus 5.5 arrives on GitHub Copilot
GitHub has rolled out Anthropic's Claude Opus 5.5 model to GitHub Copilot — distinct from Microsoft 365 Copilot — for Pro+, Max, Business, and Enterprise users. Designed for agentic coding and long-running tasks, the model embeds a text watermark that does not degrade output quality or incur token fees. Billed at provider list rates under usage-based pricing, access can be managed by enterprise administrators through policy settings.
