The disclosure comes despite Amazon being one of Anthropic's largest financial backers. The vulnerability allows Fable 5, when checking code for errors, to identify exploitable hacking security flaws. This contradicts Anthropic's claims that the model's safeguards block cyberattack assistance. Anthropic CEO Dario Amodei held urgent calls with high-level officials, including Treasury Secretary Scott Bessent. Amodei defended the safety guards as a narrow bypass, but Bessent warned him he was making a "bad decision." While officials claim they negotiated for hours, Anthropic sources say they were given only 90 minutes to disable the models. The government plans to block Fable 5 for several weeks to strengthen its cyber defenses.
