To run this extension, download a LLM that supports multimodality, and then start server.py with the appropriate `--multimodal-pipeline` argument. Examples:
```
# LLaVA 1.5 13B has the best performance
python server.py --model liuhaotian_llava-v1.5-13b --multimodal-pipeline llava-v1.5-13b --load-in-4bit
# LLaVA 1.5 7B is relatively weaker, but requires less memory
python server.py --model liuhaotian_llava-v1.5-7b --multimodal-pipeline llava-v1.5-7b --load-in-4bit
python server.py --model TheBloke_llava-v1.5-13B-GPTQ_gptq-4bit-32g-actorder_True --multimodal-pipeline llava-v1.5-13b --disable_exllama --loader autogptq
python server.py --model wojtab_llava-7b-v0-4bit-128g --multimodal-pipeline llava-7b
python server.py --model wojtab_llava-13b-v0-4bit-128g --multimodal-pipeline llava-13b
