## 🚀 Quick Start

> [!Warning]
> **Since we are updating the code frequently, please pull the latest code:**
>
> ```bash
> git pull origin main
> ```

### Fast Demo

We have supported Lumina-Next in the [diffusers](https://github.com/huggingface/diffusers).

> [!Note]
> You should install the development version of diffusers (`main` branch) before diffusers releasing the new version.
> ```bash
> pip install git+https://github.com/huggingface/diffusers

and you can try the code below:

```python
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_t2i/README.md#Installation), [Lumina-Next-T2I](./lumina_next_t2i/README.md#Installation), and [Lumina-Next-T2I-Mini](./lumina_next_t2i_mini/README.md#Installation). We highly recommend you to use the **[Lumina-Next-T2I-Mini](./lumina_next_t2i_mini/README.md#Installation)** 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-**$\alpha$.
