🚀 Quick Start

[!Warning] Since we are updating the code frequently, please pull the latest code:

git pull origin main

Fast Demo

We have supported Lumina-Next in the diffusers.

[!Note] You should install the development version of diffusers (main branch) before diffusers releasing the new version.

pip install git+https://github.com/huggingface/diffusers

and you can try the code below:

from diffusers import LuminaText2ImgPipeline
import torch

pipeline = LuminaText2ImgPipeline.from_pretrained(
"/mnt/hdd1/xiejunlin/checkpoints/Lumina-Next-SFT-diffusers", torch_dtype=torch.bfloat16
).to("cuda")

image = pipeline(prompt="Upper body of a young woman in a Victorian-era outfit with brass goggles and leather straps. Background shows an industrial revolution ciyscape with smoky skies and tall, metal structures", height=1024, width=768).images[0]

For more details about training and inference of Lumina framework, please refer to Lumina-T2I, Lumina-Next-T2I, and Lumina-Next-T2I-Mini. We highly recommend you to use the Lumina-Next-T2I-Mini for training and inference, which is an extremely simplified version of Lumina-Next-T2I with full functionalities.

Introduction

We introduce the $\textbf{Lumina-T2X}$ family, a series of text-conditioned Diffusion Transformers (DiT) capable of transforming textual descriptions into vivid images, dynamic videos, detailed multi-view 3D images, and synthesized speech. At the core of Lumina-T2X lies the Flow-based Large Diffusion Transformer (Flag-DiT)—a robust engine that supports up to 7 billion parameters and extends sequence lengths to 128,000 tokens. Drawing inspiration from Sora, Lumina-T2X integrates images, videos, multi-views of 3D objects, and speech spectrograms within a spatial-temporal latent token space, and can generate outputs at any resolution, aspect ratio, and duration.

🌟 Features:

• Flow-based Large Diffusion Transformer (Flag-DiT): Lumina-T2X adopts the flow matching formulation and is equipped with many advanced techniques, such as RoPE, RMSNorm, and KQ-norm, demonstrating faster training convergence, stable training dynamics, and a simplified pipeline.
• Any Modalities, Resolution, and Duration within One Framework:
  1. $\textbf{Lumina-T2X}$ can encode any modality, including mages, videos, multi-views of 3D objects, and spectrograms into a unified 1-D token sequence at any resolution, aspect ratio, and temporal duration.
  2. By introducing the [nextline] and [nextframe] tokens, our model can support resolution extrapolation, i.e., generating images/videos with out-of-domain resolutions not encountered during training, such as images from 768x768 to 1792x1792 pixels.
• Low Training Resources: Our empirical observations indicate that employing larger models, high-resolution images, and longer-duration video clips can significantly accelerate the convergence speed of diffusion transformers. Moreover, by employing meticulously curated text-image and text-video pairs featuring high aesthetic quality frames and detailed captions, our $\textbf{Lumina-T2X}$ model is learned to generate high-resolution images and coherent videos with minimal computational demands. Remarkably, the default Lumina-T2I configuration, equipped with a 5B Flag-DiT and a 7B LLaMA as the text encoder, requires only 35% of the computational resources compared to Pixelart-$\alpha$.
