RL for Blender isn't a GPU-burning nightmare — why more labs should try 3D design

The author debunks a widespread assumption: training AI to produce polished Blender scenes doesn't require expensive rendering on every RL rollout.
- He argues Astra-style 3D capability could do to hardware/3D design what Claude Code did to coding — Karpathy's Dec 2025 post sparked adoption across all knowledge work and drove Anthropic's historic ARR growth.
- He expects OpenAI's Astra (GPT-6) to replicate that in 3D, and urges more labs to tackle 3D design and CAD.
- Core thesis: the cost structure of RL for 3D is far more affordable than even well-informed people assume.
