ik_llama.cpp imatrix Quantizations of deepseek-ai/DeepSeek-V3.2-Speciale

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.

Some of ik's new quants are supported with Nexesenex/croco.cpp fork of KoboldCPP with Windows builds for CUDA 12.9. Also check for Windows builds by Thireus here. which have been CUDA 12.8.

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!

Perplexity computed against wiki.test.raw.

Perplexity Chart

Tis one is just a test quants for baseline perplexity comparison:

  • Q8_0 664.295 GiB (8.504 BPW)
    • Final estimate: PPL over 561 chunks for n_ctx=512 = 3.2082 +/- 0.01742

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

IQ5_K 464.467 GiB (5.946 BPW)

Final estimate: PPL over 561 chunks for n_ctx=512 = 3.2122 +/- 0.01744

Quick Start

NOTE 1: This quant has ripped out the sparse attention lightning index tensors. See sszymczyk/DeepSeek-V3.2-nolight-GGUF

NOTE 2: This model doesn't do tool calling:

Please note that the DeepSeek-V3.2-Speciale variant is designed exclusively for deep reasoning tasks and does not support the tool-calling functionality. https://huggingface.co/deepseek-ai/DeepSeek-V3.2-Speciale#how-to-run-locally

NOTE 3: The original model card has chat template discussions. These GGUFs have baked in the modified pervious Exp November release version which seems to work okay thanks to: sszymczyk
