Quants With MTP

#5

First of all, thanks a lot for the quants!

I've been able to load and run both IQ3_XXS and IQ4_XS on my hardware with actually good amount of ctx window (131k) and actually get decent decode speeds (15-16 tps - not fast by any means but ok) but more importantly, with some -ot tuning and --tensor-split, I'm able to get very decent pp speed (around 500 tps for a prompt size of 16K - opencode system prompt). The performance is much better than I expected for my hardware and the sizes are ideal, the quality also seems good.

I'm not sure if I can get more performance with MTP on my hardware and config I'm running but I wanted to try the https://github.com/stepfun-ai/llama.cpp/tree/step3p5-mtp with MTP but I realized these quants don't have the MTP heads. Would you consider uploading ones with MTP heads as well since the support also might merge into main llama.cpp soon?

If MTP gets merged into mainline llama.cpp, I'll requant it to support that.

Now that MTP has been merged into the main branch of llama.cpp, will this model be updated to support MTP?

Welp, guess I need to now 😂

I'll look into this in the next few days.

I have uploaded a few, in case anyone's interested in the meantime as options. Though I am looking forward to your updated quants AesSedai whenever you get the chance.

Coincidentally I've started converting the Step-3.7-Flash now, so I'll backfill this one too.

Actually I don't think the Step-Flash quants support MTP in llama.cpp yet: https://github.com/ggml-org/llama.cpp/pull/23274

The PR is probably close to merging, I've already got the 3.7 quants and will upload those. When MTP support merges, I'll re-quant.

I've uploaded updated 3.7-Flash quants, will be redoing the 3.5-Flash quants tonight or tomorrow.

@AesSedai , thanks a lot!

These Step-3.5-Flash quants have been updated with MTP now.
