**Status:** ✅ VALIDATED

### Multimodal Validation Notes

Qwen3-VL is a vision-language model with thinking/reasoning capabilities. The NeuronX port validates the text backbone only. `AutoModelForCausalLM` does not work for VLMs — the specific text backbone class must be used to load the HF reference for token matching.

**Note:** Qwen3-VL requires dev transformers (5.0.0.dev0). The validation uses a subprocess approach to run the HF reference in a separate venv with the dev version, allowing version isolation without affecting the main environment. With the correct text backbone extraction, the model achieves 100% token match.
