imatrix Quantization of mistralai/Devstral-Small-2-24B-Instruct-2512

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!

Quick Start

For examples check out quickstart on my ubergarm/GLM-4.7-GGUF repo. Keep in mind this is a dense model and not and MoE so will benefit from full GPU offload. Check out ik's latest -sm graph "tensor parallel" feature as well and use -t 1 when full GPU offload.

Finally, I feel like there are some tool calling / MCP / agentic use issues. When testing with my local pydantic-ai framework the server throws issues like Common part does not match fully. You might need to check into newer PRs on mainline or possibly something like this from bartowski bartowski/llama.cpp so YMMV. Good luck!
