Ovis: Structural Embedding Alignment for Multimodal Large Language Model

Ovis (Open VISion) is a novel Multimodal Large Language Model (MLLM) architecture, designed to structurally align visual and textual embeddings. For a comprehensive introduction, please refer to the Ovis paper.

Install

Ovis has been tested with Python 3.10, Torch 2.4.0, Transformers 4.46.2, and DeepSpeed 0.15.4. For a comprehensive list of package dependencies, please consult the requirements.txt file. Before finetuning or inference, please install Ovis as follows.

git clone git@github.com:AIDC-AI/Ovis.git
conda create -n ovis python=3.10 -y
conda activate ovis
cd Ovis
pip install -r requirements.txt
pip install -e .

Model

Ovis can be instantiated with popular LLMs. We provide the following Ovis MLLMs:

Performance

With 29B parameters, Ovis1.6-Gemma2-27B achieves exceptional performance in the OpenCompass benchmark, ranking among the top-tier open-source MLLMs.

With just 10B parameters, Ovis1.6-Gemma2-9B leads the OpenCompass benchmark among open-source MLLMs within 30B parameters.

Ovis1.6-Llama3.2-3B leads the OpenCompass benchmark among open-source MLLMs under 4B parameters, even surpassing Llama-3.2-11B-Vision-Instruct.

Finetune

Finetuning Ovis1.6-Gemma2-9B is supported in ms-swift.

Inference

We provide an inference wrapper in ovis/serve/runner.py, which can be used as:

from PIL import Image
from ovis.serve.runner import RunnerArguments, OvisRunner
image = Image.open('IMAGE_PATH')
text = 'PROMPT'
runner_args = RunnerArguments(model_path='MODEL_PATH')
runner = OvisRunner(runner_args)
generation = runner.run([image, text])

Based on Gradio, Ovis can also be accessed via a web user interface:

python ovis/serve/server.py --model_path MODEL_PATH --port PORT

Quantization

We quantized Ovis1.6 using AutoGPTQ. For detailed information on running and creating your own quantized version, please refer to the respective Huggingface model cards: Ovis1.6-Gemma2-9B-GPTQ-Int4 and Ovis1.6-Llama3.2-3B-GPTQ-Int4. Quantized Ovis1.6 maintains performance comparable to its non-quantized counterpart while requiring less GPU memory:

• Benchmark performance:

• GPU memory usage (max_partition=9):
