Anthropic's Fable 5 is back worldwide after a two-week government ban over a jailbreak
Quick Answer
Anthropic's Fable 5 is back in global circulation after a two-week U.S.
Quick Take
Anthropic's Fable 5 is back in global circulation after a two-week U.S. government ban due to a jailbreak exploit discovered by Amazon researchers. While a new safety classifier mitigates over 99% of such exploits, it inadvertently flags benign requests, raising concerns about user experience.
Key Points
- Fable 5 was banned for two weeks due to a jailbreak vulnerability.
- Amazon researchers identified the exploit, affecting even smaller models like Claude Haiku 4.5.
- A new safety classifier blocks over 99% of jailbreak attempts.
- The classifier may incorrectly flag harmless requests, impacting user experience.
- Anthropic resumes global shipping of Fable 5 following government clearance.
Article Excerpt
From source RSS / original summaryAfter a two-week ban, the US government is letting Anthropic ship Fable 5 globally again. Amazon researchers had found a jailbreak, but Anthropic says even much smaller models like Claude Haiku 4. 5 could pull off the same exploit. A new safety classifier blocks the technique in over 99 percent of cases, though it also flags more harmless requests in the process.

An AI model programmed nonstop for 19 days on a single MirrorCode task that cost $2,600 to run
Epoch AI's MirrorCode benchmark reveals Claude Opus 4.7 as the leader with a 56% solve rate, reconstructing a 16,000-line toolkit in 14 hours. Despite this, all models tested struggle with the most complex tasks, highlighting limitations in current AI capabilities. The single task consumed $2,600 over 19 days, raising questions about cost-effectiveness in AI development.
