I thought Anthropic models didn’t generate images.

This is SVG, but recent Anthropic models have got extremely good at other forms of visual data.

Here's a Blender model I had Claude Opus 5.5 create: https://tools.simonwillison.net/blender-viewer?url=https%3A%...

And here's some animated pixel art by Opus 5.5: https://tools.simonwillison.net/kakapo-party

And some Monkey Island style music (Opus can compose music too): https://tools.simonwillison.net/scrimshaw-jukebox

Anthropic's models do all of this by outputting code. GPT-6 Astra has similar capabilities - I got this Blender model using that: https://tools.simonwillison.net/blender-viewer?url=https%3A%...

  • Pardon, I have a lot of questions about that Scrimshaw music text format. It's clever. Did you invent it, and is it specifically intended to be written to by LLMs? Is the editor/player LLM-coded as well, and was this its recommendation for a format that would be easy for LLMs to write? I'm wondering why this instead of say, asking it to write a .MOD file.

  • Tried it with GPT-6 Astra with Ultra but the outcome was underwhelming with Blender. Maybe it was my prompting ¯\_(ツ)_/¯

  • They are really good at generating artifacts, which are windows within the replies containing all kind of visualization, often interactive.

    They are still not great at SVG. I just asked Opus and Fable to add a background to an SVG and the results were, well, not great.

I’ve been playing around with Opus 5.5 which has made a big leap over previous generations in its ability to use a simple drawing-instruction prompt to generate images.

This creates Sierra AGI-style adventure game scenes painted live from simple Turtle-esque drawing instructions so you can basically provide it an empty canvas and then position text labels on the canvas where you want certain things (tavern, oak tree, etc) and it will generate a custom script for rendering them in a EGA graphics style.

They generate svg. You can paste in pngs and they'll convert them to svg with varying degrees of success.

I've created multiple videos using Claude Code, including music and speech. It generates python which in turn generates frame PNGs that it runs through ffmpeg.

Please don't judge me too harshly for this particular poop video. But here is an example of something 100% generated with claude prompts only.

  • To clarify the ”100%” part - the Python script generated the video output, and you did nothing? No video edit at all? Then I think it is impressive! Are you able to share the prompts you used?
