Quantization of ai-sage/GigaChat3-10B-A1.8B-bf16

The pure Q8_0 quant runs on both on both mainline llama.cpp and ik_llama.cpp. The other 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.

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!

Finally, I really appreciate all the support from aifoundry.org so check out their open source RISC-V solutions, and of course huggingface for hosting all these big quants!

Quick Start

# Example running on mainline llama.cpp CPU-only
./build/bin/llama-server \
    --model "$model"\
    --alias ubergarm/GigaChat3-10B-A1.8B-GGUF \
    --ctx-size 32768 \
    --parallel 1 \
    --threads 8 \
    --host 127.0.0.1 \
    --port 8080 \
    --no-mmap \
    --jinja

Tips:

• for full offload onto GPU just add -ngl 99 and use one thread with --threads 1
• to save space on kv-cache use -ctk q8_0 which is all you need given this is MLA
• bring your own jinja chat template with --jinja --chat-template-file ./myFixedTemplate.jinja
