GGUF layer package for running NVIDIA-Nemotron-3-Ultra-550B-A55B-UD-Q4_K_XL across a local Mesh LLM cluster.
This package is derived from unsloth/NVIDIA-Nemotron-3-Ultra-550B-A55B-GGUF and keeps the original GGUF distribution split into per-layer artifacts for distributed inference.
Highlights
| Run locally | Pool multiple machines | OpenAI-compatible | Package variant |
