Preferred Operating System(s):

The integration of foundation and fine-tuned models into AI systems requires additional testing using use-case-specific data to ensure safe and effective deployment. Following the V-model methodology, iterative testing and validation at both unit and system levels are essential to mitigate risks, meet technical and functional requirements, and ensure compliance with safety and ethical standards before deployment.

The model version is NVFP4 version and is quantized with nvidia-modelopt v0.44.0

This model was obtained by quantizing the weights and activations of Qwen3.5-122B-A10B to NVFP4 data type, ready for inference with vLLM. Only the weights and activations of the linear operators within transformer blocks in MoE are quantized. This model was obtained by quantizing the weights and activations of Qwen3.5-122B-A10B to NVFP4 data type the number of bits per parameter from 16 to 4 reducing the disk size and GPU memory requirements by approximately 4x.

To serve this checkpoint with vLLM, you can start the docker docker: nvcr.io/nvidia/vllm:26.04-py3 and run the sample command below:

The accuracy benchmark results are presented in the table below:

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.

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.
