Did Anthropic Just Declaw Claude Fable 5?

Claude Fable 5 shipped with its teeth filed off: no hacking, no bio, no training a rival. The guys called it too dangerous to exist. Days later, it was gone. Anthropic took Mythos, its most capable and most dangerous model, gated off the parts it was best at, and shipped what was left as Claude Fable 5. Hunter Powers and Daniel Bishop go through exactly what got restricted: cybersecurity and hacking, biology and chemistry, and anything that helps you train a competing model. Ask Fable 5 a security question and it does not refuse, it quietly hands the request down to Claude Opus, a weaker model, and lets that one say no. We get into why a lab would defang its own best model right before going public, what that says about protecting the moat, and whether Fable 5 is worth roughly twice the price of Opus 4.8 when heavy use burns two hundred dollars an hour. Then the part that hits your job. Both hosts handed Fable 5 a goal, walked away, and came back to finished software. Hunter built a playable liminal-space data center game with a live DeepSeek integration. Daniel built a Sisyphus mobile game, art and all, wired to Google's Nano Banana Pro. Anthropic says Fable 5 autonomously migrated fifty million lines of code for Stripe. So is software engineering dead? Daniel calls it, period, full stop, and we argue about what that leaves for the people who used to write the code. We also get into the one-million-token context window and why you compact it early, Cursor's benchmark putting Fable 5 first in quality and first in cost, and AI budgets as a line item in your next salary negotiation. Plus the case for using a frontier model to orchestrate cheaper Opus, Sonnet, and DeepSeek sub-agents, and whether self-awareness comes from one giant model or a committee of small ones. They Might Be Self-Aware is the AI podcast from The Blur, reported from inside the dissolving line between human and machine, not from a safe distance.
