[ERNIE-Image] is a powerful and highly efficient image generation model with 8B parameters. Currently there's only two models to be released:

ModelHugging Face
ERNIE-Imagehttps://huggingface.co/baidu/ERNIE-Image
ERNIE-Image-Turbohttps://huggingface.co/baidu/ERNIE-Image-Turbo

ERNIE-Image

ERNIE-Image is designed with a relatively compact architecture and solid instruction-following capability, emphasizing parameter efficiency. Based on an 8B DiT backbone, it provides performance that is comparable in some scenarios to larger (20B+) models, while maintaining reasonable parameter efficiency. It offers a relatively stable level of performance in instruction understanding and execution, text generation (e.g., English / Chinese / Japanese), and overall stability.

ERNIE-Image-Turbo

ERNIE-Image-Turbo is a distilled variant of ERNIE-Image, requiring only 8 NFEs (Number of Function Evaluations) and offering a more efficient alternative with relatively comparable performance to the full model in certain cases.

ErnieImagePipeline

Use [ErnieImagePipeline] to generate images from text prompts. The pipeline supports Prompt Enhancer (PE) by default, which enhances the user’s raw prompt to improve output quality, though it may reduce instruction-following accuracy.

We provide a pretrained 3B-parameter PE model; however, using larger language models (e.g., Gemini or ChatGPT) for prompt enhancement may yield better results. The system prompt template is available at: https://huggingface.co/baidu/ERNIE-Image/blob/main/pe/chat_template.jinja.

If you prefer not to use PE, set use_pe=False.
