IQ2XXS for us on the edge?

Hey thanks for your work, I have your Qwen 3.5 122B@iQ2XXS quant and seems solid (granted haven't gone too deep with him) but saw you never updated it and wonder why? Could you maybe do one for this new Nemotron? For the 32R/16VR crowd trying to hold on? Also did you find something wrong with your other iQ2XXS and is that why you didn't update the quant like all the others?

Hi @rkh661, honestly I wasn't really aware people were using the IQ2_XXS so when I redid them I just did my usual line-up. I don't think that 32+16 is really viable for this model since the ffn_down_exps can't be quanted below Q4_0. Even unsloth's smallest quants are 52.7GB so you just aren't going to get lower than that really.

I'll redo the IQ2_XXS with the fused expert for the Qwen3.5-122B and upload it though.

Ok @AesSedai , I gotcha. with some of these newer architecture's they don't play nice going down to the redline. But thanks anyways and appreciate you uploading the updated iQ2XXS for Qwen 3.5 122B! He's been sharp and some of these big guys can go low, if you throw every trick we have at em with hybrid quants, and imatrix, and all the rest, so thank you sir! 🫡

@rkh661 The fused Qwen3.5-122B-A10B IQ2_XSS has been uploaded.
