I have been using a PR branch to run GLM 5.3 flash locally so I have been watching the dueling PRs develop to implement it and all the comments and reviews. You're right the scale of it is huge. The speed with which maintainers and community are responding is also super impressive.

I know there's a lot of discussion about AI overwhelming OS maintainers and I can see that. It does seem like llama.cpp is successfully riding that dragon right now though.
