This is terrifying. Evidently based on prior art by Mr. Pizlo – indeed, where's the acknowledgement of that?? (edit: I missed it) – but I'm assuming that was never translated into code.

I love the idea of experimentation and innovation; I abhor the idea of it being dependent on Anthropic and their theft. I've never rooted for the Chinese labs more strongly than after seeing this.

The acknowledgement is in the PR description, section "The design, and what it's based on".
