Post Training Quantization
This model was obtained by quantizing the weights and activations of Qwen3-Next-80B-A3B-Thinking to NVFP4 data type, ready for inference with TensorRT-LLM. 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 3.3x.
Usage
Deploy with TensorRT-LLM
To deploy the quantized checkpoint with TensorRT-LLM LLM API, follow the sample codes below:
- LLM API sample usage:
from tensorrt_llm import LLM, SamplingParams
from tensorrt_llm.llmapi import KvCacheConfig
def main():
prompts = [
"Hello, my name is",
"The president of the United States is",
"The capital of France is",
"The future of AI is",
]
sampling_params = SamplingParams(temperature=0.6, top_p=0.95)
kv_cache_config = KvCacheConfig(enable_block_reuse=False)
llm = LLM(model="nvidia/Qwen3-Next-80B-A3B-Thinking-NVFP4", tensor_parallel_size=4, kv_cache_config=kv_cache_config)
outputs = llm.generate(prompts, sampling_params)
# Print the outputs.
for output in outputs:
prompt = output.prompt
generated_text = output.outputs[0].text
print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")
# The entry point of the program needs to be protected for spawning processes.
if __name__ == '__main__':
main()
