It runs both q2 and original (4 bit routed experts). At the same speed more or less. The q2 quants are not what you could expect: it works extremely well for a few reasons. For the full model you need a Mac with 256GB.

Out of curiosity, do you have any theories of why it works so well at such aggressive quantization levels?
It's a mix of extreme sparsity but with the routed expert doing a non trivial amount of work (and it is q8), and projections and routing not being quantized as well. Also the fact it's a QAT model must have a role I guess, and I quantized routed experts out layers with Q2 instead of IQ2_XXS to retain quality.
