glm-4.7-nvfp4-pruned-8experts

Pruned Active-Slice Notice

This checkpoint is not the full upstream nvidia/GLM-4.7-NVFP4 checkpoint. It is a routed-MoE active-slice pruned from the local NVFP4 weights.

• Source checkpoint: nvidia/GLM-4.7-NVFP4
• Pruned routed experts: original expert ids 0, 1, 2, 3, 4, 5, 6, 7
• Routed expert count after pruning: 8
• Experts per token after pruning: 8
• Shared experts: preserved unchanged (n_shared_experts=1)
• Sparse/MoE blocks preserved: layers 3..92 (90 blocks, including the MTP block)
• Output safetensor shards: 9
• Output tensor count: 11,071
• Serialized tensor bytes: 43,052,331,904

The original local config has 160 routed experts and activates 8 experts per token. This active slice keeps exactly one native activation set worth of routed experts, preserves dense/attention/shared-expert/MTP weights, slices router gates and biases to eight experts, and preserves each retained expert's associated NVFP4 quantization tensors. See PRUNING_RATIONALE.md and prune_report.json.

Model Overview

Description:

The NVIDIA GLM-4.7 NVFP4 model is the quantized version of ZAI's GLM-4.7 model, which is an auto-regressive language model that uses an optimized transformer architecture. For more information, please check here. The NVIDIA GLM-4.7 NVFP4 model is quantized with Model Optimizer.

This model is ready for commercial/non-commercial use. <br>

Third-Party Community Consideration

This model is not owned or developed by NVIDIA. This model has been developed and built to a third-party's requirements for this application and use case; see link to Non-NVIDIA (GLM-4.7) Model Card from ZAI.

Post Training Quantization

This model was obtained by quantizing the weights and activations of GLM-4.7 to NVFP4 data type, ready for inference with SGLang. Only the weights and activations of the linear operators within transformer blocks in MoE are quantized.

Usage

To serve this checkpoint with SGLang, you can start the docker lmsysorg/sglang:nightly-dev-cu13-20260318-cb1e63ab and run the sample command below:

python3 -m sglang.launch_server --model nvidia/GLM-4.7-NVFP4 --tensor-parallel-size 4 --quantization modelopt_fp4 --tool-call-parser glm47 --reasoning-parser glm45 --trust-remote-code --chunked-prefill-size 131072  --mem-fraction-static 0.80

Evaluation

The accuracy benchmark results are presented in the table below:

Baseline: GLM-4.7-FP8. Benchmarked with temperature=1.0, top_p=0.95, max num tokens 131072

Model Limitations:

The base model was trained on data that contains toxic language and societal biases originally crawled from the internet. Therefore, the model may amplify those biases and return toxic responses especially when prompted with toxic prompts. The model may generate answers that may be inaccurate, omit key information, or include irrelevant or redundant text producing socially unacceptable or undesirable text, even if the prompt itself does not include anything explicitly offensive.

Ethical Considerations

NVIDIA believes Trustworthy AI is a shared responsibility and we have established policies and practices to enable development for a wide array of AI applications. When downloaded or used in accordance with our terms of service, developers should work with their internal model team to ensure this model meets requirements for the relevant industry and use case and addresses unforeseen product misuse.
