🔥 InternVL3_5-8B-FP8-Dynamic 🔥

This is a fp8 dynamic (w8a8) version of OpenGVLab/InternVL3_5-8B, optimized for high-performance inference with vLLM. The model utilizes fp8 dynamic (w8a8) for optimal performance and deployment.

Just Run It (vLLM serve)

You can serve the model using vLLM's OpenAI-compatible API server.

bash

vllm serve brandonbeiler/InternVL3_5-8B-FP8-Dynamic \
    --quantization compressed-tensors \
    --served-model-name internvl3_5-8b \
    --reasoning-parser qwen3 \
    --trust-remote-code \
    --max-model-len 32768 \
    --tensor-parallel-size 1 # Adjust based on your GPU setup

Notes

32k max context length
reasoning parser ready to go, requires system prompt to run in thinking mode
still investigating tool calling
