GitHub Copilot adds Claude Fable 5.2 with data kept by default

GitHub tells that Claude Fable 5.2, the newest model of Anthropic, is available to all users of GitHub Copilot, its AI coding tool. GitHub tells that the first tests show it did more tasks than Fable 5.1, with fewer steps and tool calls. GitHub gave no numbers. Anthropic keeps prompts and outputs by default for safety checks.

What is new

The model is for hard coding tasks with many steps across large codebases. Users of Copilot Pro+, Max, Business and Enterprise plans can select it in tools such as Visual Studio Code. The release is in steps. The price is the list price of the provider.

The proof

GitHub gave no test numbers. It tells only that Fable 5.2 did more tasks than Fable 5.1 with fewer steps. It also tells that the model did hard tasks that older models missed.

The data rules

Administrators of Business and Enterprise plans must start a policy. It is off by default. To start it is to accept data retention. Anthropic tells that it does not use retained data to train its models. Eligible enterprises can keep zero data retention until the end of the year. After that, they must have Enterprise Frontier Safeguards, which adds automated monitoring.

Insight: Data retention is the price of the strongest Claude models

AWS GovCloud also gives Fable 5.2 with data kept for safety checks, and its zero data retention is also short. Anthropic tells that the new price is 20% lower. Anthropic is maybe the one that sets the data rules in all clouds and tools. Enterprise Frontier Safeguards is maybe the next gate for all of them. Set your data rules at this time.
