Trump officials demand Anthropic guarantee Fable 5 guardrails cannot be bypassed, which security experts call technically impossible

Story Overview

Trump administration officials have told Anthropic that Fable 5 cannot return to public availability until the company can demonstrate its guardrails are immune to every possible bypass, a threshold security experts describe as unachievable under current or foreseeable technology. The demand follows the model's brief launch in early June and its rapid suspension after export-control orders tied to reported jailbreaks.

Trump administration officials say that no algorithms that can check if an answer is correct in polynomial time can be shipped to the public unless it can also be proven that a solution cannot be found in polynomial time.

Trump administration officials tell WIRED that if Anthropic wants to rerelease Fable 5, it will need to ensure the model's guardrails can't be circumvented. Security experts say that can't be done. https://www.wired.com/story/the-white-house-wants-anthropic-to-block-all-jailbreaks-that-may-not-be-possible/?utm_brand=wired&utm_social-type=owned&utm_source=twitter&utm_medium=social&utm_campaign=aud-dev

Open Question

Why the bar may stay out of reach

Experts view guardrails as temporary measures that skilled users and future models will inevitably circumvent, with one analysis likening the requirement to proving an unsolvable P vs NP problem. No technical criteria or timeline for compliance have been released, leaving the re-release path undefined.

Policy Risk

The suspension's ripple effects

Global access to Fable 5 was halted within days of launch to meet the export restrictions, and the new conditions add further uncertainty around when or whether the model returns to API or platform availability.

Sentiment

Many users objected to the Trump administration demanding Anthropic make its Fable models impossible to jailbreak, calling the policy stupid overreach that will dumb down AI and labeling the government a joke or mad king.

That sounds very bad for a soon-to-be re-release of Fable 5.

"Trump administration officials tell WIRED that if Anthropic wants to rerelease Fable 5, it will need to ensure the model's guardrails can't be circumvented. Security experts say that can't be done."

If this is true, we probably wont see a Fable 5 re-release any time soon.

@the_engi_nerd White House demands Anthropic prove that any problem whose known solution can be verified algorithmicly in polynomial time can also be solved algorithmicly in polynomial time

@NAHBEECH Yeah, I posted about that earlier. What did these guys expect? If you say “this technology is dangerous” and then release it to the world, you better believe the government is going to have something to say about it

NEW: The White House is reportedly demanding Anthropic make Fable 5 impossible to jailbreak before rerelease — which security experts say “can’t be done.”

@kimmonismus skilled users can also use an ide to hack into stuff are we now supposed to put guardrails on that too

Bob is right@MeridaMX2025

You are correct we are never going to get fable. This whole thing was just a kabuki Theatre. Everything was so convenient. The G7 summit all these regulations dead switch kills switch bullshit switch licensing it all the stipulation before it can come back unrealistic. Don’t you think we are done we have reached the ceiling of AI. No other model will surpass fable so there’s nothing to hope for I don’t even understand why they’re releasing IPOs for these AI companies I wouldn’t invest in them. It’s a dead end.
