🚀 New Video: Claude Fable 5 Built This in Claude Code and I'm Blown Away
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.
