Post Training Quantization

This model was obtained by quantizing the weights and activations of Qwen3.6-27B to NVFP4 data type, ready for inference with vLLM. Only the weights and activations of the linear operators within transformer blocks are quantized. This optimization reduces the number of bits per parameter from 16 to 4, reducing the disk size and GPU memory requirements by approximately 2.5x.

Usage

To serve this checkpoint with vLLM, you can start the docker vllm/vllm-openai:nightly and run the sample command below:

vllm serve nvidia/Qwen3.6-27B-NVFP4 --port 8000 --quantization modelopt --max-model-len 262144 --reasoning-parser qwen3

Baseline: Qwen3.6-27B-FP8. Benchmarked with temperature=1.0, top_p=0.95, max_num_tokens=81920 except SciCode with temperature=0.6, and τ²-Bench Telecom with temperature=0.0 and top_p=1.0.

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. 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.
