Using Blender with coding agents on macOS — Modern frontier models have got *really good* at using Blender. I've been having a lot of fun trying this out recently - models can produce `.blend` files you can edit in Blender itself, and can also render images and even movies (by rendering a sequence of images and combining them with `ffmpeg`).

I've been having fun with Blender in ChatGPT Codex on my Mac recently. Getting it to work with coding agents is really easy: install the full Mac application from blender.org and run a prompt like this:

\n
\n

Use the already install /Applications/Blender to render a scene of a pelican riding a bicycle

\n
\n

In this case I followed that up with these two prompts:

\n
\n

OK add a background and a lot of flair

\n
\n

Then:

\n
\n

OK make it a whole lot better

\n
\n

And got this image, generated using Blender's Python API:

\n

\"A

\n

This was covered by my existing Codex subscription, but according to AgentsView it would have cost $4.24 at API prices for gpt-6-astra.
