NVIDIA-Nemotron-3.5-Lightning-30B-A3B-GGUF

GGUF quantizations of nvidia/NVIDIA-Nemotron-3.5-Lightning-30B-A3B-BF16, converted with llama.cpp for fast local inference on CPU/GPU.

Files

Quant Use case
F16 Full precision, reference quality
Q8_0 Near-lossless, largest quant size
Q6_K Very high quality, minimal loss
Q5_K_M / Q5_K_S High quality, good balance
Q4_K_M / Q4_K_S Recommended default — best speed/quality tradeoff
Q4_0 Legacy 4-bit, faster on some hardware
Q3_K_L / Q3_K_M / Q3_K_S Lower RAM, noticeable quality drop
Q2_K Smallest, most compressed, quality degrades

Usage

Run with llama.cpp, Ollama, LM Studio, or any GGUF-compatible runtime:

./llama-cli -m NVIDIA-Nemotron-3.5-Lightning-30B-A3B-Q4_K_M.gguf -p "Your prompt here"

Notes

  • This is a Mixture-of-Experts (A3B) architecture — check RAM/VRAM requirements before choosing a quant.
  • For most users, Q4_K_M offers the best balance of speed, size, and output quality.
  • Quantized using automated pipeline on Modal with llama.cpp's conversion and quantization tools.
