Post Training Quantization

This model was obtained by quantizing the weights and activations of Llama 4 Scout 17B 16E Instruct to FP4 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 serve the quantized checkpoint with TensorRT-LLM , follow the sample commands below with the TensorRT-LLM GitHub repo:

• LLM API sample usage:

import asyncio
from tensorrt_llm import LLM, SamplingParams


def main():

    llm = LLM(model="nvidia/Llama-4-Scout-17B-16E-Instruct-FP4", attn_backend="FLASHINFER", backend="pytorch", tensor_parallel_size=8)

    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=0.8, top_p=0.95)
    async def task(prompt: str):
        output = await llm.generate_async(prompt, sampling_params)
        print(
            f"Prompt: {output.prompt!r}, Generated text: {output.outputs[0].text!r}"
        )

    async def main():
        tasks = [task(prompt) for prompt in prompts]
        await asyncio.gather(*tasks)

    asyncio.run(main())


# The entry point of the program need to be protected for spawning processes.
if __name__ == '__main__':
    main()
