Quick Start With HuggingFace

Example Code
from llava.model.builder import load_pretrained_model
from llava.mm_utils import get_model_name_from_path
from llava.eval.run_llava import eval_model

model_path = "liuhaotian/llava-v1.5-7b"

tokenizer, model, image_processor, context_len = load_pretrained_model(
    model_path=model_path,
    model_base=None,
    model_name=get_model_name_from_path(model_path)
)

Check out the details wth the load_pretrained_model function in llava/model/builder.py.

You can also use the eval_model function in llava/eval/run_llava.py to get the output easily. By doing so, you can use this code on Colab directly after downloading this repository.

model_path = "liuhaotian/llava-v1.5-7b"
prompt = "What are the things I should be cautious about when I visit here?"
image_file = "https://llava-vl.github.io/static/images/view.jpg"

args = type('Args', (), {
    "model_path": model_path,
    "model_base": None,
    "model_name": get_model_name_from_path(model_path),
    "query": prompt,

LLaVA Weights

Please check out our Model Zoo for all public LLaVA checkpoints, and the instructions of how to use the weights.

Demo

Gradio Web UI

To launch a Gradio demo locally, please run the following commands one by one. If you plan to launch multiple model workers to compare between different checkpoints, you only need to launch the controller and the web server ONCE.

Launch a controller

python -m llava.serve.controller --host 0.0.0.0 --port 10000

Launch a gradio web server.

python -m llava.serve.gradio_web_server --controller http://localhost:10000 --model-list-mode reload

You just launched the Gradio web interface. Now, you can open the web interface with the URL printed on the screen. You may notice that there is no model in the model list. Do not worry, as we have not launched any model worker yet. It will be automatically updated when you launch a model worker.

Launch a SGLang worker

This is the recommended way to serve LLaVA model with high throughput, and you need to install SGLang first. Note that currently 4-bit quantization is not supported yet on SGLang-LLaVA, and if you have limited GPU VRAM, please check out model worker with quantization.

pip install "sglang[all]"

You'll first launch a SGLang backend worker which will execute the models on GPUs. Remember the --port you've set and you'll use that later.

# Single GPU
CUDA_VISIBLE_DEVICES=0 python3 -m sglang.launch_server --model-path liuhaotian/llava-v1.5-7b --tokenizer-path llava-hf/llava-1.5-7b-hf --port 30000

# Multiple GPUs with tensor parallel
CUDA_VISIBLE_DEVICES=0,1 python3 -m sglang.launch_server --model-path liuhaotian/llava-v1.5-13b --tokenizer-path llava-hf/llava-1.5-13b-hf --port 30000 --tp 2

Tokenizers (temporary): llava-hf/llava-1.5-7b-hf, llava-hf/llava-1.5-13b-hf, liuhaotian/llava-v1.6-34b-tokenizer.

You'll then launch a LLaVA-SGLang worker that will communicate between LLaVA controller and SGLang backend to route the requests. Set --sgl-endpoint to http://127.0.0.1:port where port is the one you just set (default: 30000).

python -m llava.serve.sglang_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --sgl-endpoint http://127.0.0.1:30000

Launch a model worker

This is the actual worker that performs the inference on the GPU. Each worker is responsible for a single model specified in --model-path.

python -m llava.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path liuhaotian/llava-v1.5-13b

Wait until the process finishes loading the model and you see "Uvicorn running on ...". Now, refresh your Gradio web UI, and you will see the model you just launched in the model list.

You can launch as many workers as you want, and compare between different model checkpoints in the same Gradio interface. Please keep the --controller the same, and modify the --port and --worker to a different port number for each worker.

python -m llava.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port <different from 40000, say 40001> --worker http://localhost:<change accordingly, i.e. 40001> --model-path <ckpt2>

If you are using an Apple device with an M1 or M2 chip, you can specify the mps device by using the --device flag: --device mps.

Launch a model worker (Multiple GPUs, when GPU VRAM <= 24GB)

If the VRAM of your GPU is less than 24GB (e.g., RTX 3090, RTX 4090, etc.), you may try running it with multiple GPUs. Our latest code base will automatically try to use multiple GPUs if you have more than one GPU. You can specify which GPUs to use with CUDA_VISIBLE_DEVICES. Below is an example of running with the first two GPUs.

CUDA_VISIBLE_DEVICES=0,1 python -m llava.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path liuhaotian/llava-v1.5-13b

Launch a model worker (4-bit, 8-bit inference, quantized)

You can launch the model worker with quantized bits (4-bit, 8-bit), which allows you to run the inference with reduced GPU memory footprint, potentially allowing you to run on a GPU with as few as 12GB VRAM. Note that inference with quantized bits may not be as accurate as the full-precision model. Simply append --load-4bit or --load-8bit to the model worker command that you are executing. Below is an example of running with 4-bit quantization.

python -m llava.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path liuhaotian/llava-v1.5-13b --load-4bit

Launch a model worker (LoRA weights, unmerged)

You can launch the model worker with LoRA weights, without merging them with the base checkpoint, to save disk space. There will be additional loading time, while the inference speed is the same as the merged checkpoints. Unmerged LoRA checkpoints do not have lora-merge in the model name, and are usually much smaller (less than 1GB) than the merged checkpoints (13G for 7B, and 25G for 13B).

To load unmerged LoRA weights, you simply need to pass an additional argument --model-base, which is the base LLM that is used to train the LoRA weights. You can check the base LLM of each LoRA weights in the model zoo.

python -m llava.serve.model_worker --host 0.0.0.0 --controller http://localhost:10000 --port 40000 --worker http://localhost:40000 --model-path liuhao

What is this?LLaVA is an open-source large multimodal chatbot: a vision-language model you can show images to and talk with, built by visual instruction tuning toward GPT-4V-level capabilities (NeurIPS 2023 Oral).
So is it an app I install, or code and model weights?Neither a hosted app nor a plain library: it is a research codebase with Python training and eval scripts plus pretrained checkpoints in a Model Zoo, typically run as a local Gradio web UI.
How do I get it running?Clone the repo, install the Python package and grab weights from the Model Zoo, then launch three processes: a controller, a model worker that runs the model on your GPU, and a Gradio web server you open in a browser.
Does my machine have to run Linux?For installation, effectively yes — the README tells non-Linux users to stop and follow separate macOS and Windows instructions instead. On Apple M1/M2 chips the model worker can target the mps device via --device mps.
Is the Apache-2.0 license all I need to know?Not quite: the code is Apache-2.0, but datasets and checkpoints keep their original licenses — the training data falls under OpenAI's Terms of Use, and LLaMA-2/Vicuna checkpoints under the Llama community license.
How much GPU do I need?With 4-bit quantization, inference runs on a GPU with as little as 12GB VRAM, and with under 24GB the code can split across multiple GPUs automatically. Training has been verified on RTX 3090 and RTX A6000.
Can I run LLaVA without a beefy NVIDIA GPU?Yes, with trade-offs: LLaVA is supported in llama.cpp with 4-bit and 5-bit quantization for CPU-friendly setups, and the repo also added support for Intel dGPU and CPU platforms. Quantized inference is somewhat less accurate than full precision.
Does it actually work on video?Surprisingly well: LLaVA-NeXT (Video) showed the image-only-trained model is strong on video tasks through zero-shot modality transfer, and DPO training with AI feedback on videos yields significant improvement.
What came out of this project besides the main model?Several research spin-offs: LLaVA-Med for biomedicine, LLaVA-Plus agents that learn to use tools, LLaVA-Interactive for combined chat, segmentation and generation, an RLHF variant to reduce hallucination, and the Korean Ko-LLaVA.
