@claudeai Can anyone tell me what it means? Does it mean we can only use Fable 50% of our total limits? and Is it for free on them or does it still take our limits?
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 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.
Sakana AI, a Japanese startup, has unveiled Fugu Ultra, a model promising frontier-level capabilities by acting as a smart orchestrator for existing AI powerhouse models.
According to Sakana, Fugu dynamically delegates specific tasks to models like Gemini or Claude behind the scenes, keeping the exact process proprietary. Early beta feedback and benchmarks indicate that Fugu Ultra holds its own against—and sometimes beats—industry giants like GPT-5.5, Gemini 3.1 Pro, and Fable 5.
The company intends to evolve the system over time by absorbing newer, more efficient models, including Sakana's own upcoming releases.
