InternVL3-8B-FP8-Dynamic

🔥 InternVL3-8B-FP8-Dynamic: Optimized Vision-Language Model 🔥

This is a FP8 dynamic quantized version of OpenGVLab/InternVL3-8B, optimized for high-performance inference with vLLM. The model utilizes dynamic FP8 quantization for optimal ease of use and deployment, achieving significant speedup with minimal accuracy degradation on vision-language tasks.

🔧 Usage

With vLLM (Recommended)

from vllm import LLM, SamplingParams

# Load the quantized model
model = LLM(
    model="brandonbeiler/InternVL3-8B-FP8-Dynamic",
    trust_remote_code=True,
    max_model_len=8192,
    tensor_parallel_size=1,  # Adjust based on your GPU setup
)
# Generate response
sampling_params = SamplingParams(temperature=0.7, max_tokens=512)
response = model.generate("Describe this image: <image>", sampling_params)
print(response[0].outputs[0].text)
