Claude Fable 5.2 Arrives in GitHub Copilot

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

Copilot Pro+, Max, Business, and Enterprise users can select the model in the model picker in Visual Studio Code, Visual Studio, Copilot CLI, the GitHub Copilot coding agent, the GitHub Copilot app, github.com, GitHub Mobile on iOS and Android, JetBrains IDEs, Xcode, and Eclipse. The rollout will be gradual, so users who do not see the model yet should check back soon. The model is billed at provider list pricing under usage-based billing.

Fable 5.2 requires data retention by default so Anthropic can operate its safety classifiers. Anthropic retains data, including prompts and outputs, for that purpose, and the retained data is not used to train its models. Certain eligible enterprise customers can use zero data retention instead.

Why it matters

The model may suit teams that rely on Copilot for large, multistep work, since GitHub reports it finishes more tasks with fewer steps. The data retention requirement is a meaningful change for organizations with strict data policies, and it departs from the zero data retention default that other Claude models in Copilot still follow.

What to do

Copilot Business and Enterprise administrators must turn on the Claude Fable 5.2 policy in Copilot settings. The policy is off by default, and enabling it acknowledges the retention requirement. Confirm current pricing, eligibility for zero data retention, and the timeline for Anthropic’s Enterprise Frontier Safeguards on GitHub’s Models and pricing page and Anthropic’s documentation before rolling the model out.
