Fable 5 Ban: 4 Open Models Responded Before Anthropic Could Restore Access

My take: Let me be honest: this one left me thinking. Fable 5 is now 16 days offline with no return date. The US government blocked it on June 12 over an alleged jailbreak (a technique for getting around safety limits) that could expose vulnerabilities in classified software, meaning a serious security matter, not a whim. Mythos 5 started coming back yesterday for critical infrastructure. But here is what caught my eye: while Anthropic did the right thing and sat down to negotiate with Washington, four open-weight models did not waste a minute. Cohere shipped North Mini Code, Moonshot launched Kimi K2.7-Code (one trillion parameters and an open license), and Z.ai updated GLM-5.2, all within the same ban window. And the customers who depended only on Fable moved in real time. The lesson I have been repeating for a while: tying your business to a single AI provider is pure risk, no matter how good it is. The market does not wait for anyone to settle its disputes; the second-best model fills your gap in hours. Always keep a plan B. 📌
