Mirror of Alpha-VLLM/Lumina-Image-2.0, republished by Unsloth. The weights are unmodified. See NOTICE and the licence file in this repo for the terms, which are the upstream terms and are unchanged.

Lumina-Image-2.0 is a 2 billion parameter flow-based diffusion transformer capable of generating images from text descriptions. For more information, visit our GitHub.

Gradio Demo

We provide an official Gradio demo. You can use the link we provided to try it out.

Usage

python

import torchfrom diffusers import Lumina2Pipeline
pipe = Lumina2Pipeline.from_pretrained("Alpha-VLLM/Lumina-Image-2.0", torch_dtype=torch.bfloat16)pipe.enable_model_cpu_offload() #save some VRAM by offloading the model to CPU. Remove this if you have enough GPU power
prompt = "A serene photograph capturing the golden reflection of the sun on a vast expanse of water. The sun is positioned at the top center, casting a brilliant, shimmering trail of light across the rippling surface. The water is textured with gentle waves, creating a rhythmic pattern that leads the eye towards the horizon. The entire scene is bathed in warm, golden hues, enhancing the tranquil and meditative atmosphere. High contrast, natural lighting, golden hour, photorealistic, expansive composition, reflective surface, peaceful, visually harmonious."image = pipe(    prompt,    height=1024,    width=1024,    guidance_scale=4.0,    num_inference_steps=50,    cfg_trunc_ratio=0.25,    cfg_normalization=True,    generator=torch.Generator("cpu").manual_seed(0)).images[0]image.save("lumina_demo.png")

This is a Hugging Face Diffusers implementation of the paper Lumina-Image 2.0: A Unified and Efficient Image Generative Framework.
