Claude Fable 5.2 generally available in GitHub Copilot

GitHub says Anthropic's Claude Fable 5.2 is now generally available in GitHub Copilot for Pro+, Max, Business, and Enterprise users, billed at provider list pricing under usage-based billing.

Business and Enterprise administrators must turn on the Claude Fable 5.2 policy in Copilot settings, where it is off by default. The model requires data retention by default to run Anthropic's safety classifiers; certain eligible enterprise customers can use it with zero data retention through the end of the calendar year under a time-bound exemption while Anthropic rolls out Enterprise Frontier Safeguards.

GitHub says its early testing found Fable 5.2 solved more tasks than Fable 5.1 using fewer steps and tool calls, and completed difficult tasks earlier models missed. These results come from GitHub's own testing and have not been independently verified.
