GLM-4.7-Flash-NVFP4-GGUF

GGUF quantization of zai-org/GLM-4.7-Flash — a 30B-parameter Mixture-of-Experts language model with ~3.2B active parameters per token, built on the DeepSeek2 architecture with Multi-head Latent Attention (MLA) and 64 routed experts.

Quantized to NVFP4 format for efficient inference with minimal quality loss.

About NVFP4

NVFP4 is NVIDIA's native 4-bit floating-point format (E4M3) for Blackwell GPUs. It stores weights in FP4 with a shared per-block scale, enabling native Blackwell tensor core acceleration with no dequantization overhead during inference. Compared to INT4 formats, NVFP4 offers better dynamic range (E4M3 vs E2M1) and maintains higher quality at similar bit widths.
