# LLaVA Model Card
## SGLang
This contains the necessary files to run LLaVA-1.6 34B on SGLang. You can run the server with the following command:
`python -m sglang.launch_server --model-path dillonlaird/hf-llava-v1.6-34b --port 30000`
There seems to be issues with the chat formatting when using the sglang interface so I recommend querying the server directly and formatting the string yourself:
```python
import requests
from transformers import AutoTokenizer
def generate(image_path: str, prompt: str, tokenizer):
chat = [
{"role": "system", "content": "Answer the question."},
{"role": "user", "content": "<image>\n" + prompt},
]
chat_str = tokenizer.apply_chat_template(chat, tokenize=False)
chat_str += "<|img_start|>assistant\n"
sampling_params = {"temperature": 0.2, "max_new_tokens": 1536}
res = requests.post(
"http://localhost:30000/generate",
json={
"text": chat_str,
"image_data": image_path,
"sampling_params": sampling_params,
},
)
return res.json()["text"]
if __name__ == "__main__":
tokenizer = AutoTokenizer.from_pretrained("liuhaotian/llava-v1.6-34b")
image_path = "path/to/image.jpg"
prompt = "What is the name of the mountain?"
desc = generate(image_path, prompt, tokenizer)
```
## Model details
**Model type:**
LLaVA is an open-source chatbot trained by fine-tuning LLM on multimodal instruction-following data.
It is an auto-regressive language model, based on the transformer architecture.
Base LLM: [NousResearch/Nous-Hermes-2-Yi-34B](https://huggingface.co/NousResearch/Nous-Hermes-2-Yi-34B)
**Model date:**
LLaVA-v1.6-34B was trained in December 2023.
