Claude Fable 5.2 is generally available in GitHub Copilot, with data retention required by default

GitHub says Claude Fable 5.2, Anthropic's newest Fable model, is now generally available in GitHub Copilot for complex, multistep coding tasks across large codebases. It says that in early testing Fable 5.2 solved more tasks than Fable 5.1 while using fewer steps and tool calls, and completed hard tasks earlier models missed.

Availability. The model is offered to Copilot Pro+, Max, Business and Enterprise users, in the model picker of Visual Studio Code, Visual Studio, Copilot CLI, the Copilot coding agent, the Copilot app, github.com, GitHub Mobile, JetBrains IDEs, Xcode and Eclipse. GitHub says the rollout is gradual. It is billed at provider list pricing under usage-based billing.

Admin policy. On Copilot Business and Enterprise, administrators must turn on the Claude Fable 5.2 policy, which is off by default; leaving it off keeps the model unavailable to the organization.

Data retention. GitHub says Fable 5.2 requires data retention by default: Anthropic keeps prompts and outputs to run its safety classifiers, and says the retained data is not used to train its models. Fable 5 and Fable 5.1 have the same requirement; other Claude models stay under zero data retention. Enabling the policy counts as acknowledging it.

Zero data retention. Eligible enterprises can use Fable 5.2, 5.1 and 5 with zero data retention through the end of the calendar year, under a time-bound exemption while Anthropic rolls out Enterprise Frontier Safeguards (EFS); after that, continued use requires EFS. Eligibility is determined through the customer's GitHub account team, not GitHub Support, and approval does not enable the model on its own.
