Gemma-4 QAT Special Unsloth quants
Hey folks! We converted Gemma-4 QAT quants in a different way since a direct llama.cpp Q4_0 loses accuracy when converting from BF16 QAT directly.
E2B for example has a mean KLD of 0.00173 vs 0.05109 (29x better relatively) for a naive Q4_0 quantization, and ours is even 22% smaller!
is there going be a 2 bit XL of this one
is there going be a 2 bit XL of this one
No unfortunately if you go any lower, the accuracy degrades quite a bit
Could you upload MTP GGUF's of the QAT'd assistants?
If mixing QAT LLM with non-QAT MTP, the results are poor.
Was iMatrix used for this gguf?

+1 QAT assistant. Llama.cpp support has been merged.
Will it be possible to have IQ4_NL rather than Q4_0 ?
I'm just wondering: Which version is better?
unsloth/gemma-4-26B-A4B-it-UD-Q5_K_S.gguf
vs
unsloth/gemma-4-26B-A4B-it-qat-UD-Q4_K_XL.gguf
Maybe the first one, or?
@christian3137 If you only use English and do typical tasks (general chat, coding, tools calling, STEM) then the UD-Q5_K_S will probably be better (and even the UD-Q4_K_XL will probably be better). If you use non-Latin languages ββ(in particular, if you are engaged in translation) and some unusual tasks (like roleplay), then QAT will be better only because it quantizes all data equally (in 4 bits). However, in the latter case, it is better to choose APEX-Balanced (without "I").
wait so why is this a problem for Q4_0 and QAT specifically?
wouldn't it be also a problem for other quants like Q4_K with non-QAT where it also uses FP16 instead of BF16 while the model is BF16?
