I am aware of all that. They literally never say “they used mxfp4 in some weights”. What you’re claiming they said doesn’t exist. This isn’t a postmortem, it’s PR fluff without actually addressing the issue.

32GB vram is more than enough for Qwen 3.5 35b You can just load the Q4_K_XL model like normal, and put all tensors on GPU without any -ot or --cpu-moe flags. If you need a massive context for some reason where model+kv cache won't fit

The Q4_K_XL is easily the most popular quant for the model, though. So then why was Q4_K_XL having issues? Is it just a PPL issue that doesn't reflect in real world usage? If yes, why not just say that? "The Q4_K_XL had lower PPL,

Yeah, I saw that yesterday. The blog post does not explain why/how the Qwen 3.5 quants uploaded on 2/27 are different from the files uploaded on 2/24. Old 2/24 Q4_K_XL commit (pre bugfix files): https://huggin

I'm aware of that, but that's not the link of the post. The post is linking to their UD 2.0 quants from a few months back. Also, the benchmarks are because they messed up the first version of their Qwen 3.5 XL quants by quanting s

It's also literally factually incorrect. Pretty much the entire field of mechanistic interpretability would obviously point out that models have an internal definition of what a bug is. Here's the most approachable paper that show

It was good for like, one month. Qwen3 30b dominated for half a year before that, and GLM-4.7 Flash 30b took over the crown soon after Nemotron 3 Nano came out. There was basically no time period for it to shine.

That seems like a nonissue for the purposes of this discussion though, in terms of user uptake. Tiktok and Facebook and other websites aren't exactly focused on serving to people on the same network.
