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

A developer used Anthropic's Claude Fable 5 to build a Figma clone in a single 28-minute session, adding 2,889 lines of code and passing 22 smoke tests. The US government issued an export control directive on June 12, causing Anthropic to pull the model worldwide just three days after its launch. The developer notes the timing coincides with OpenAI's confidential S-1 filing and upcoming IPO.

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.
