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.

Introducing Claude Opus 4.6. Our smartest model got an upgrade.
Opus 4.6 plans more carefully, sustains agentic tasks for longer, operates reliably in massive codebases, and catches its own mistakes.
It’s also our first Opus-class model with 1M token context in beta.
100% of Next.js evals pass with a small 8KB change to the agents md and providing the Next.js documentation.
Teach your agent about all Next.js features:
npx @next/codemod@canary agents-md
This will apply the change to your preferred config and download the relevant documentation for the installed version.
The codemod approach will help us prove out the changes before bringing this into Next.js core as a feature.
We've been researching the effectiveness of skills, agents md, and other approaches. While skills do solve more evals, it doesn't solve all evals. Whereas the agents md covers all evals.

Great work and research by @gao_jude.
We just released 𝚛𝚎𝚊𝚌𝚝-𝚋𝚎𝚜𝚝-𝚙𝚛𝚊𝚌𝚝𝚒𝚌𝚎𝚜, a repo for coding agents.
React performance rules and evals to catch regressions, like accidental waterfalls and growing client bundles.
How we collected them and how to install the skill ↓
