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.

We’ve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
We'll begin restoring access tomorrow, and will share an update soon.
We’re grateful to our users for their patience, and to everyone who worked with us on redeploying the models.
Met a guy making $1.4 million a year as a prompt engineer.
I asked him how he learned prompting so well.
He sent me a video that was never supposed to get out. Andrew Ng's 2 hour prompting course.
You wont find anything better about prompting than this video.
I watched it last night.
Halfway through, I realized I have been using Claude completely wrong for years.

Introducing Claude Sonnet 5, our most agentic Sonnet yet.
It makes plans, uses tools like browsers and terminals, and runs autonomously at a level that just a few months ago required larger and more expensive models.
Introducing Claude Science, a new app designed with every stage of research in mind.
Artifacts traced to their code, environments managed on demand, and 60+ optional scientific databases that you can connect.
Available now in beta.
Spacex just bought Cursor for $60 billion.
the same day, Kevin Niparko ( Product Lead at Cursor) showed exactly what Elon bet on:
"we're moving towards an era of loops and agent systems
where agents are going to continue to be working on our behalf at all times"
13 minutes that laid out the next five years of how software gets built: agent swarms + loops.
i wrote the full guide on building agent swarms two weeks ago.
