Cosmos-Reason2-32B GGUF

Pure GGUF conversion of nvidia/Cosmos-Reason2-32B.

Built on NVIDIA Cosmos.

Files

Cosmos-Reason2-32B-BF16.gguf: BF16 text backbone GGUF.
Cosmos-Reason2-32B-Q4_K_M.gguf: smaller 4-bit text backbone GGUF for lower memory use.
Cosmos-Reason2-32B-Q5_K_M.gguf: balanced 5-bit text backbone GGUF with better quality than Q4.
Cosmos-Reason2-32B-Q8_0.gguf: larger 8-bit text backbone GGUF for higher quality.
mmproj-Cosmos-Reason2-32B-F16.gguf: F16 multimodal projector / vision GGUF.

Use one text backbone file together with the mmproj file for multimodal inference.

Hardware estimates

These are rough inference estimates for llama.cpp with batch size 1. Actual memory use depends on context length, image/video inputs, backend, and how many layers are offloaded to GPU.

Text backbone	File size	Text + mmproj	Suggested system RAM	Suggested VRAM for mostly/full GPU offload	Notes
`Q4_K_M`	19.8 GB	21.0 GB	32 GB minimum, 48 GB comfortable	24 GB tight, 32 GB comfortable	Best first choice for local use.
`Q5_K_M`	23.2 GB	24.4 GB	48 GB comfortable	32 GB comfortable	Better quality than Q4 with moderate extra memory.
`Q8_0`	34.8 GB	36.0 GB	64 GB comfortable	48 GB+ recommended	Higher quality, much larger.
`BF16`	65.5 GB	66.7 GB	96 GB+ recommended	80 GB+ or multi-GPU	Original precision GGUF; not a practical default for most local machines.

KV cache adds roughly 2 GiB per 8k text tokens at fp16 cache precision, before additional image/video token overhead. Reduce --ctx-size or use partial CPU/GPU offload if memory is tight.

Source

Original model: https://huggingface.co/nvidia/Cosmos-Reason2-32B

This GGUF conversion was produced with llama.cpp convert_hf_to_gguf.py from the original Hugging Face safetensors.

Usage

Use one text backbone file together with the multimodal projector in llama.cpp:

llama-server \
  -m Cosmos-Reason2-32B-Q4_K_M.gguf \
  --mmproj mmproj-Cosmos-Reason2-32B-F16.gguf

BF16 and Q8_0 are large and may require CPU offload or a multi-GPU setup.
