Anthropic (@AnthropicAI): "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.

@AnthropicAI can you fix claude code? Today is like talking to a 1bit quant of Opus, speaking Chinese, forgets how to wait for sub agents, etc.

I don't get it... So what would you use Fable for?
No cyber security, no frontier mod dev, no coding, no debugging...

LOL!!!!!! Pass. I had a claude max subscription for the last 5 months, this is definitely not how to retain customers.<br>1. We're going to handicap the model by not allowing it to debug. 2. We're going to allow you 5 days to use it at 50% of your weekly usage. 3. We're going to charge you by credits after that.
WHAT A JOKE!
