AIDC-AI/Ovis-Image-7B

Built upon Ovis-U1, Ovis-Image is a 7B text-to-image model specifically optimized for high-quality text rendering, designed to operate efficiently under stringent computational constraints.

The overall architecture of Ovis-Image (cf. Fig.2 in our report).

🏆 Highlights

• Strong text rendering at a compact 7B scale: Ovis-Image is a 7B text-to-image model that delivers text rendering quality comparable to much larger 20B-class systems such as Qwen-Image and competitive with leading closed-source models like GPT4o in text-centric scenarios, while remaining small enough to run on widely accessible hardware.
• High fidelity on text-heavy, layout-sensitive prompts: The model excels on prompts that demand tight alignment between linguistic content and rendered typography (e.g., posters, banners, logos, UI mockups, infographics), producing legible, correctly spelled, and semantically consistent text across diverse fonts, sizes, and aspect ratios without compromising overall visual quality.
• Efficiency and deployability: With its 7B parameter budget and streamlined architecture, Ovis-Image fits on a single high-end GPU with moderate memory, supports low-latency interactive use, and scales to batch production serving, bringing near–frontier text rendering to applications where tens-of-billions–parameter models are impractical.

✨ Showcase

Here are some examples demonstrating the capabilities of Ovis-Image.

🛠️ Inference

Inference with Diffusers

First, install the diffusers library with support for Ovis-Image.

pip install git+https://github.com/DoctorKey/diffusers.git@ovis-image

Next, use the OvisImagePipeline to generate the image.

import torch
from diffusers import OvisImagePipeline

pipe = OvisImagePipeline.from_pretrained("AIDC-AI/Ovis-Image-7B", torch_dtype=torch.bfloat16)
pipe.to("cuda")
prompt = "A creative 3D artistic render where the text \"OVIS-IMAGE\" is written in a bold, expressive handwritten brush style using thick, wet oil paint. The paint is a mix of vibrant rainbow colors (red, blue, yellow) swirling together like toothpaste or impasto art. You can see the ridges of the brush bristles and the glossy, wet texture of the paint. The background is a clean artist's canvas. Dynamic lighting creates soft shadows behind the floating paint strokes. Colorful, expressive, tactile texture, 4k detail."
image = pipe(prompt, negative_prompt="", num_inference_steps=50, true_cfg_scale=5.0).images[0]
image.save("ovis_image.png")

Inference with Pytorch

Ovis-Image has been tested with Python 3.10, Torch 2.6.0, and Transformers 4.57.1. For a full list of package dependencies, please see requirements.txt.

git clone [email protected]:AIDC-AI/Ovis-Image.git
conda create -n ovis-image python=3.10 -y
conda activate ovis-image
cd Ovis-Image
pip install -r requirements.txt
pip install -e .

For text-to-image, please run

python ovis_image/test.py \
    --model_path AIDC-AI/Ovis-Image-7B/ovis_image.safetensors \
    --vae_path AIDC-AI/Ovis-Image-7B/ae.safetensors \
    --ovis_path AIDC-AI/Ovis-Image-7B/Ovis2.5-2B \
    --image_size 1024 \
    --denoising_steps 50 \
    --cfg_scale 5.0 \
    --prompt "A creative 3D artistic render where the text \"OVIS-IMAGE\" is written in a bold, expressive handwritten brush style using thick, wet oil paint. The paint is a mix of vibrant rainbow colors (red, blue, yellow) swirling together like toothpaste or impasto art.
