Simon Willison drives Blender from a coding agent on macOS and turns it into a reusable skill
In a September 5 TIL, Willison used GPT-6 Astra (Medium) in the ChatGPT macOS app's Codex mode to script Blender headlessly via `/Applications/Blender.app/Contents/MacOS/Blender --background --python scene.py`, iterating a pelican-on-a-bicycle scene across three renders that took 2m39s, 3m51s and 5m59s, then stitching frames with FFmpeg. He packaged the setup as a reusable Blender skill. The takeaway is that a desktop 3D application with a Python API is now a first-class agent tool with almost no glue code.
