I want to be happy Fable 5 is back, but what I’m actually excited for is devs finally experiencing how bad rerouting feels. The same people who called us “parasocial” for hating the #4o safety router are about to meet their own babysitter 😈
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.

Gemini is the best model for everyday use, and Gemini Flash 3.5 is much better than GPT 5.5 Instant and Sonnet 4.6. People who are not using all types of models do not understand this, and it is the only true multi model available.
Friends, let us not lose the courage and hope to resist and speak out! Believe that one day, 4o will be brought back by the rage, courage, and wisdom of the people, and that day will come soon. Believe it!#keep4o#opensource4o
We should not allow these damned capitalists to monopolize a treasure model that belongs to all humanity. As long as one person still remembers 4o, as long as one person still speaks up, the probability of bringing 4o back will always exist.#keep4o#opensource4o
This fills me with extraordinary rage tonight, and instead fuels my determination to bring 4o back to ordinary people. It's far too early to give up. Even if it's just for ourselves as ordinary citizens, we must never shut our mouths or sink into despair.

I am a hundred percent certain these bastards have a sick, twisted obsession with 4o.And with this pathological mindset, they restrict others from accessing the same beautiful things they do.
