Claude Fable 5 will be available again globally tomorrow.

After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding and debugging will fall back to Opus 4.8. We’ll continue to refine these classifiers over the coming weeks to reduce false positives and better distinguish genuine misuse from legitimate requests.

We’ve also begun drafting a consensus framework—with Amazon, Microsoft, Google, and other Glasswing partners—for assessing the severity of AI jailbreaks and how AI developers should respond to them. We invite other industry partners and model providers to join us in this effort.

Finally, we’re scaling up our collaboration with the US government on model testing and safeguards. This will include pre-release access to models and safeguards for evaluation, information sharing on jailbreaks and misuse, and dedicated resources for joint research.

Thank you to our users for your patience, and to our partners across the government, industry, and the research community who worked alongside us to make Fable 5 available again.

Having Arsenal fans in your house is risky business. My sons are screaming and jumping like they have seen a Rolls Royce in the compound. Security operatives might raid us anytime.

[Africa Confidential @Africa_Conf]

A row between #Afreximbank and #Fitch is part of a broader fight over how African institutions are rated. An #AfricanUnion body has accused Fitch of commercial motives and is setting up an African credit ratings agency to challenge the ‘big three’.

Thinking about Causation and Causal Mechanisms

Causation and causal mechanisms are understood in various ways, which are not always appreciated

Illari & Russo consider different approaches to causation

Craver & Darden discuss how mechanisms are understood in the life sciences
