GLM-4.6-NVFP4
Quantized version of GLM-4.6 using LLM Compressor and the NVFP4 (E2M1 + E4M3) format.
This time it actually works! We think
This should be the start of a new series of hopefully optimal NVFP4 quantizations as capable cards continue to grow out in the wild.
Model Summary
| Property | Value |

Description
This model is a drop-in replacement for GLM-4.6 that runs in NVFP4 precision, enabling up to 6× faster GEMM throughput and around 65 % lower memory use compared with BF16. Accuracy remains within ≈ 1 % of the FP8 baseline on standard reasoning and coding benchmarks.
