I had a few days of preview access, which was long enough to put together a plugin for LLM. You can try the model out in the terminal like this:

  uv tool install llm
  llm install llm-meta-ai
  llm keys set meta-ai
  # paste API key here
  llm -m meta-ai/muse-spark-1.1 "Generate an SVG of a pelican riding a bicycle"

Here's the result: https://tools.simonwillison.net/markdown-svg-renderer#url=ht...

For comparison, here's the pelican I got from Muse Spark 1: https://simonwillison.net/2026/Apr/8/muse-spark/
