`ik_llama.cpp` imatrix Quantizations of Qwen/Qwen3.5-122B-A10B

The quants in this collection REQUIRE ik_llama.cpp fork to support the ik's latest SOTA quants and optimizations! Do not download these big files and expect them to run on mainline vanilla llama.cpp, ollama, LM Studio, KoboldCpp, etc!

NOTE ik_llama.cpp can also run your existing GGUFs from bartowski, unsloth, mradermacher, etc if you want to try it out before downloading my quants. Only a couple quants in this collection are compatible with mainline llamma.cpp/LMStudio/KoboldCPP/etc as mentioned in the specific description, all others require ik_llama.cpp.

Some of ik's new quants are supported with Nexesenex/croco.cpp fork of KoboldCPP with Windows builds. Also check for ik_llama.cpp windows builds by Thireus here..

These quants provide best in class perplexity for the given memory footprint.

Big Thanks

Shout out to Wendell and the Level1Techs crew, the community Forums, YouTube Channel! BIG thanks for providing BIG hardware expertise and access to run these experiments and make these great quants available to the community!!!

Also thanks to all the folks in the quanting and inferencing community on BeaverAI Club Discord and on r/LocalLLaMA for tips and tricks helping each other run, test, and benchmark all the fun new models! Thanks to huggingface for hosting all these big quants!

Finally, I really appreciate the support from aifoundry.org so check out their open source RISC-V based solutions!

Quant Collection

Perplexity computed against wiki.test.raw. (lower is "better")

These two are just test quants for baseline perplexity comparison and not available for download here:

BF16 227.525 GiB (16.005 BPW)
- PPL over 580 chunks for n_ctx=512 = 4.8159 +/- 0.02839
Q8_0 120.942 GiB (8.508 BPW)
- PPL over 580 chunks for n_ctx=512 = 4.8196 +/- 0.02841

NOTE: The first split file is much smaller on purpose to only contain metadata, its fine!

IQ5_KS 77.341 GiB (5.441 BPW)

Final estimate: PPL over 580 chunks for n_ctx=512 = 4.8264 +/- 0.02846

This is the best quality version for full offload on 96GB VRAM. This is it.
