Claude Fable 5.2 Now Generally Available in GitHub Copilot
GitHub CopilotGitHub made Claude Fable 5.2 generally available in GitHub Copilot for complex, multistep coding tasks across large codebases. GitHub reports that in early testing it solved more tasks than Claude Fable 5.1 with fewer steps and tool calls. It is available on Pro+, Max, Business and Enterprise plans across ten clients, billed at provider list pricing, with a data retention requirement that organization admins must accept.
Key Takeaways
- Claude Fable 5.2 is generally available in GitHub Copilot, succeeding Fable 5.1 as the Claude option for complex coding.
- GitHub reports it solved more tasks than Fable 5.1 with fewer steps and tool calls in early testing.
- It is available on Pro+, Max, Business and Enterprise plans and in ten clients including VS Code, JetBrains, Xcode and GitHub Mobile.
- Billing follows usage-based provider list pricing rather than a fixed premium multiplier.
- Data retention is required by default so Anthropic can run safety classifiers, and retained data is not used for training.
- Eligible enterprises can keep zero data retention through the end of the year, after which Enterprise Frontier Safeguards are needed.
A New Claude Model for Large, Multistep Coding Work
GitHub made Claude Fable 5.2 generally available in GitHub Copilot. The model targets complex, multistep coding tasks across large codebases. In early testing, GitHub reports that Claude Fable 5.2 solved more tasks than Claude Fable 5.1 while using fewer steps and tool calls, which matters for long agent sessions where every extra tool call adds time and cost.
Where and How to Use It
Claude Fable 5.2 is offered to Copilot Pro+, Max, Business and Enterprise subscribers. Developers pick it from 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. Rollout is gradual, so developers who do not yet see the model should check back later. Usage is billed under usage-based billing at the provider's list pricing, and GitHub links to its models and pricing documentation for the exact rates.
Admin Policy and Data Retention
On Copilot Business and Enterprise, an administrator must enable the Claude Fable 5.2 policy in Copilot settings, and it is off by default. Unlike most other Claude models in Copilot, Fable 5.2 requires data retention by default so Anthropic can run safety classifiers that detect harmful use. Anthropic does not use the retained data to train its models. Enabling the policy acknowledges the retention requirement, and leaving it off keeps the model unavailable to the organization. Other Claude models, apart from Fable 5, 5.1 and 5.2, continue to use zero data retention.
Zero Data Retention Exemption for Eligible Enterprises
Eligible enterprise customers 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. After that, continued use requires Anthropic's Enterprise Frontier Safeguards, which add automated safety monitoring and more data retention options, including customer-controlled storage and encryption keys. Eligibility is determined through the GitHub account team, GitHub Support cannot determine it, and approval does not switch the models on automatically: an administrator must still enable the policy.
