"MXFP4 is much worse on many tensors - attn_gate, attn_q, ssm_beta, ssm_alpha using MXFP4 is not a good idea, and rather Q4_K is better - also MXFP4 uses 4.25 bits per weight, whilst Q4_K uses 4.5 bits per weight. It's better to use Q4_K than MXFP4 when choosing between them."
The Q4 quants had a mixture of mxfp4 leading to worse outcomes.
Nope. Where do they say something along the lines of "we had MXFP4 tensors in our previous upload" or "that's why we re-uploaded new versions"?
This is a famous non-apology non-explanation of what actually happened. "They made it clear by showing how it really affected various tensors terribly"? Where do they even say they had ever previously uploaded any quant with MXFP4?
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.
