Claude Fable 5 is here. Learn how to run Anthropic's new Mythos class model through a real agentic coding workflow in Claude Code so you can build a browser based ray tracing game from a single prompt, without writing the rendering engine yourself. In this video, I put Claude Fable 5 to the test with one genuinely hard challenge: build a browser based game with real reflections and ray tracing, including its own rendering, shader, camera, and material systems. You'll learn how to select Fable 5 in Claude Code and tune the reasoning effort, plan and break the build into feature files using my RAMP framework, and implement every feature on autopilot with background review agents, then compare the result against GPT 5.5. Want to try the game yourself? https://claude-fable-5-mirror-game.vercel.app/

Big one. Friday evening the US government ordered Anthropic to pull its two newest models, Fable 5 and Mythos 5, citing national security. The order targeted foreign nationals, but to actually comply Anthropic had to shut both models off for everyone, worldwide. Only those two are affected, everything else still works fine. Anthropic is pushing back, saying the security concern is minor and that other public models can do the same thing. They're calling it a misunderstanding and trying to get access restored. Here's their full statement: https://www.anthropic.com/news/fable-mythos-access Since a lot of us aren't in the US, this one actually affects us directly. Where do you land?

If you've ever watched a tutorial and thought "I could never build that myself," this one's for you. The 7 Day Builder Challenge is now live in the Classroom. It's completely free, one short lesson a day, and by the end of the week you'll have built a real, working app with a coding agent, even if you've never finished a project before. How it works: - One bite-sized lesson a day for 7 days - You follow along and build as you go - By day 7 you'll have a real app you made yourself No experience needed. Start with Day 1 and move at your own pace. 👉 Jump in here: https://www.skool.com/leonvanzyl/classroom/0f5fd684?md=193bafde45d94cf38fa151c9135b4cfb
