We named tonight's meetup "The Mythos/Fable Edition" after Anthropic's big launch. By the time we actually meet, the models are already gone. The whole thing lasted three days.
On 9 June, Anthropic released Claude Fable 5 and Mythos 5, pitching Fable 5 as its most capable widely-released model and aiming it squarely at long-horizon agentic work. It went out the same day across the Claude API, AWS Bedrock, Microsoft Foundry and the rest.
Then on Friday 12 June, the US Commerce Department directed Anthropic to block foreign nationals from using both models. Rather than carve the world in two, Anthropic disabled Fable 5 and Mythos 5 globally for everyone the same day. As best anyone can tell, the government believes a way to jailbreak Fable 5 surfaced, and the standoff traces back to Anthropic refusing to hand over full access to Claude.
Worth noting from down here: "foreign nationals" includes us. So even setting the jailbreak drama aside, a Sydney developer poking at Fable 5 over the weekend would have watched it blink out regardless.
It's a strange one to sit with. The most capable model anyone had shipped, public on a Tuesday and pulled by Friday, on government order. If you're building agentic tooling on the BEAM, it's a sharp reminder that the model under your abstraction can disappear out from under you. Plan for the provider, and the politics, not just the API.
