It's also very hard to figure out how to run a model like this. There's no installer.

Yes, there is. It's called Claude Code. Point it at the HuggingFace URL and say "Download these weights and build whatever is needed to run them, then test the model."

I really miss the time when people thought that the idea of someone telling an un-sandboxed AI "do whatever is needed to X" was unrealistically stupid.
