NVILA is a family of open VLMs designed to optimize both efficiency and accuracy for efficient video understanding and multi-image understanding . Building on top of VILA, we improve its model architecture by first scaling up the spatial and temporal resolutions, and then compressing visual tokens. This "scale-then-compress" approach enables NVILA to efficiently process high-resolution images and long videos. We also conduct a systematic investigation to enhance the efficiency of NVILA throughout its entire lifecycle, from training and fine-tuning to deployment. NVILA matches or surpasses the accuracy of many leading open and proprietary VLMs across a wide range of image and video benchmarks. At the same time, it reduces training costs by 4.5×, fine-tuning memory usage by 3.4×, pre-filling latency by 1.6-2.2×, and decoding latency by 1.2-2.8×. We make our code and models available to facilitate reproducibility.
- [2024/12] We release NVILA (a.k.a VILA2.0) that explores the full stack efficiency of multi-modal design, achieving cheaper training, faster deployment and better performance.
- [2024/12] We release LongVILA that supports long video understanding, with long-context VLM with more than 1M context length and multi-modal sequence parallel system.
- [2024/10] VILA-M3, a SOTA medical VLM finetuned on VILA1.5 is released! VILA-M3 significantly outperforms Llava-Med and on par w/ Med-Gemini and is fully opensourced! code model
- [2024/10] We release VILA-U: a Unified foundation model that integrates Video, Image, Language understanding and generation.
- [2024/07] VILA1.5 also ranks 1st place (OSS model) on MLVU test leaderboard.
- [2024/06] VILA1.5 is now the best open sourced VLM on MMMU leaderboard and Video-MME leaderboard!
- [2024/05] We release VILA-1.5, which offers video understanding capability. VILA-1.5 comes with four model sizes: 3B/8B/13B/40B.

Prompt: Elaborate on the visual and narrative elements of the video in detail.
Response: The video features a person with red nail polish meticulously working on a piece of fabric with a black and white checkered pattern. The individual is dressed in a black top with a red inner layer. The setting includes a white table where various tools such as a ruler, a pencil, and a pin are placed. The person is seen folding the fabric in a precise manner, creating a triangular shape. The background includes a greenish cabinet with drawers, adding a contrasting color to the scene. Throughout the video, the text 'Country Sampler' is visible in the bottom right corner, indicating the source or brand associated with the content. The video emphasizes the careful and detailed process of fabric folding, showcasing the person's skill and attention to detail.

./environment_setup.sh vilaVILA training contains three steps, for specific hyperparameters, please check out the scripts/v1_5 folder:
We utilize LLaVA-CC3M-Pretrain-595K dataset to align the textual and visual modalities.
The stage 1 script takes in two parameters and it can run on a single 8xA100 node.
bash scripts/NVILA-Lite/align.sh Efficient-Large-Model/Qwen2-VL-7B-Instruct <alias to data>and the trained models will be saved to runs/train/nvila-8b-align.
bash scripts/NVILA-Lite/stage15.sh runs/train/nvila-8b-align/model <alias to data>and the trained models will be saved to runs/train/nvila-8b-align-1.5.
We use MMC4 and Coyo dataset to train VLM with interleaved image-text pairs.
bash scripts/NVILA-Lite/pretrain.sh runs/train/nvila-8b-align-1.5 <alias to data>and the trained models will be saved to runs/train/nvila-8b-pretraining.
This is the last stage of VILA training, in which we tune the model to follow multimodal instructions on a subset of M3IT, FLAN and ShareGPT4V. This stage runs on a 8xA100 node.
bash scripts/NVILA-Lite/sft.sh runs/train/nvila-8b-pretraining <alias to data>and the trained models will be saved to runs/train/nvila-8b-SFT.
We have introduce vila-eval command to simplify the evaluation. Once the data is prepared, the evaluation can be launched via
MODEL_NAME=NVILA-15B
MODEL_ID=Efficient-Large-Model/$MODEL_NAME
huggingface-cli download $MODEL_ID
vila-eval \
--model-name $MODEL_NAME \
--model-path $MODEL_ID \
--conv-mode auto \
--tags-include localit will launch all evaluations and return a summarized result.
We provide vila-infer for quick inference with user prompts and images.

Our VILA models are quantized by AWQ into 4 bits for efficient inference on the edge. We provide a push-the-button script to quantize VILA with AWQ.
We support AWQ-quantized 4bit VILA on GPU platforms via TinyChat. We provide a tutorial to run the model with TinyChat after quantization. We also provide an instruction to launch a Gradio server (powered by TinyChat and AWQ) to serve 4-bit quantized VILA models.
We further support our AWQ-quantized 4bit VILA models on various CPU platforms with both x86 and ARM architectures with our TinyChatEngine. We also provide a detailed tutorial to help the users deploy VILA on different CPUs.
A simple API server has been provided to serve VILA models. The server is built on top of FastAPI and Huggingface Transformers. The server can be run with the following command:
python -W ignore server.py \
--port 8000 \
--model-path Efficient-Large-Model/NVILA-15B \
--conv-mode autodocker build -t vila-server:latest .
docker run --gpus all --ipc=host --ulimit memlock=-1 --ulimit stack=67108864 \
-v ./hub:/root/.cache/huggingface/hub \
-it --rm -p 8000:8000 \
-e VILA_MODEL_PATH=Efficient-Large-Model/NVILA-15B \
-e VILA_CONV_MODE=auto \
vila-server:latestThen you can call the endpoint with the OpenAI SDK as follows:
from openai import OpenAI
client = OpenAI(
base_url="http://localhost:8000",
api_key="fake-key",
)
response = client.chat.completions.create(

# "url": "data:image/png;base64,<base64_encoded_image>",
},
},
],
}
],
model="NVILA-15B",
)
