Cover image for I used Claude Fable 5 for 28 minutes. Then the US government shut it down.

Franck LEBAS

I had 3 days with it. That's all anyone got.

Claude Fable 5 launched June 9. I immediately threw it at something non-trivial: a Figma clone. Not a toy. A real canvas editor with layers panel, design panel, multi-frame support, infinite canvas, and undo history.

Here's what /cost showed after the session:

Total cost:            $9.54
Total duration (wall): 28m 29s
Total code changes:    2889 lines added, 7 lines removed

claude-fable-5: 6.8k input, 93.8k output, 2.4m cache read

Ctrl-Z worked. 22 smoke tests passed. Headless rendering was compliant.

For context: this is the kind of thing a junior dev would spend several days on. Fable did it in one session, with a simple prompt, without losing architectural coherence.

Then on June 12 at 5:21 PM ET, the US government issued an export control directive. Anthropic pulled the model immediately, for everyone, worldwide, no explanation given.


Here's what I find hard to ignore.

Anthropic spent months documenting why Fable was safe for general use. Defense-in-depth classifiers. Opus 4.8 as a safety fallback on high-risk domains. No universal jailbreak found in testing. They published the evidence.

OpenAI filed its S-1 confidentially on May 22. IPO targeted for Q4 2026. The US government holds a stake.

Fable 5 was, by most benchmarks, the most capable model publicly available. It was suspended 3 days after launch.

I'm not drawing a direct line between those facts. I'm just saying the timing is what it is.


Anthropic did the safety work seriously. They got cut anyway.

OpenAI is losing $1.22 for every $1 of revenue, heading to an IPO, and ChatGPT keeps running fine.

This is America.


I'll update this post when Fable comes back. My bet: shortly after the OpenAI IPO closes.
