This post has been marked as a dupe, but it provides a lot more details than the other announcements of Fable's re-enablement provide:

> The export control directive on June 12 came after the government became aware of a report in which Amazon researchers had found a method of bypassing Fable 5’s safeguards: prompting it so that it identified a number of software vulnerabilities. In one case, the model produced code demonstrating how the relevant vulnerability could be exploited. Over the past two weeks, we have worked closely with the government and other partners, including Amazon, to review the report and evidence.

> Our testing confirmed that many less capable models—including Claude Opus 4.8, GPT-5.5, and Kimi K2.7—could identify the same vulnerabilities as Fable 5 did in the report. When it came to the demonstration of how to exploit the single vulnerability, every model we tested could produce the same demonstration as Fable 5 (including Claude Haiku 4.5, Sonnet 4.6, Opus 4.6, Opus 4.7, Opus 4.8, GPT-5.4, GPT-5.5, and Kimi K2.7).

This indicates three things:

1) WTF was Amazon thinking? Didn't their researches try the same thing in other models too before telling the CEO to tell the government it was dangerous (!?)

2) Anthropic - in particular Dario - really needs to learn government relations better. Most of the problems Anthropic has had with the government seem to stem from Dario's attitude rather than actual facts. (Eg, the DoD debacle seems to have ended up with OpenAI signing almost the same contract Anthropic already had, just worded differently)

3) The administration decision making is just wacky. In a normal administration they'd have actual policy documents you could look at to understand under what circumstances they think models have a problem. With this they just seem to make it up as they go, and the tools they use make no sense at all. If it is dangerous for cyber security reasons why would export controls make sense to use?

This may be in Anthropic's benefit. Autonomous killer drones will be widely deployed by the US military, and at that time, Anthropic can point to them and say "see, we were trying to avoid that"
