No Bartowski's are more affected - (38% NaN) than ours (22%) - for MiniMax 2.7 see https://www.reddit.com/r/LocalLLaMA/comments/1slk4di/minimax...
We already fixed ours. Bart hasn't yet but is still working on it following our findings.
blk.61.ffn_down_exps in Q4_K or Q5_K failed - it must be in Q6_K otherwise it overflows.
For the others, yes layers in some precision don't work. For eg Qwen3.5 ssm_out must be minimum Q4-Q6_K.
ssm_alpha and ssm_beta must be Q8_0 or higher.
Again Bart and others apply our findings - see https://www.reddit.com/r/LocalLLaMA/comments/1rgel19/new_qwe...
Thanks again, TIL
