Try DGX Spark playbooks using Nix on DGX OS, or install NixOS on your DGX Spark for the full Nix experience. The repository provides USB images and a NixOS module with settings for DGX Spark systems.

This works on the NVIDIA DGX Spark itself and also on the Asus Ascent GX10.

See my 5 minute lightning talk from Planet Nix for an intro: https://youtu.be/AvK_gi_snJE?si=MPKv3iiuS9B5elIE

Been running this on a few Asus GX10 machines with k3s on top, it’s been great. I’m running the new deepseek.

Thank you for your work!

What quant are you using, and what tps are you getting with K3?

This is incredible. I have a Jetson lying around and will try to it out on this. I use it to play with vision models, not LLMs, and have been wanting a better way to manage the machine.

Thanks for sharing, saving this for when I get a DGX Spark

The FP8 version from DeepSeek themselves [0], around 1800 tps prefill and 45 tokens per second decode.

I’ve been running a custom VLLM image with b12x as well as nvfp4_ds_mla.

I would say it’s quite fantastic in day to day, I use it mostly in Hermes and sometimes for coding.

I have qwen 3.6 27b on an rtx 6000 pro as well so I use that as a workhorse in pi with DS as a reviewer/planner.

Edit: I think you may have misread my post. k3s is NOT kimi k3, and I did mention I was running deepseek.

Huge plus to anyone interested in the space to check out what Graham built here!

If anyone is also interested on Nix/CUDA/Capital Markets/Flox, we recently did another case study in the space - https://flox.dev/blog/deploying-hardened-flox-nvidia-cuda-st...
