# GLM-4.6-NVFP4
|
| 12 |
+
|
| 13 |
+
**Quantized version of [GLM-4.6](https://huggingface.co/zai-org/GLM-4.6)** using **LLM Compressor** and the **NVFP4** (E2M1 + E4M3) format.
|
| 14 |
+
|
| 15 |
+
**This time it actually works!** *We think*
|
| 16 |
+
|
| 17 |
+
This should be the start of a new series of *hopefully optimal* NVFP4 quantizations as capable cards continue to grow out in the wild.

## Description
|
| 36 |
+
|
| 37 |
+
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.
|
| 38 |
+
Accuracy remains within ≈ 1 % of the FP8 baseline on standard reasoning and coding benchmarks.
