Video and Image Generation Using Flow-Based Transformers

The evolution of artificial intelligence in media generation has reached new heights with the introduction of Goku, a china's new Ai breakthrough after Omnihuman-1, a state-of-the-art joint image-and-video generative model. Developed using rectified flow Transformers, Goku Ai is designed to produce high-quality visuals with exceptional accuracy, coherence, and efficiency. This article delves into the technological advancements, architecture, training methodologies, and performance benchmarks of Goku, making it a game-changer in AI-driven video generation.

1. Understanding Goku: What Sets It Apart?

Goku is a generative foundation model that integrates image and video generation into a unified framework. Unlike previous generative models that focused either on static images or videos separately, Goku uses rectified flow-based learning and Transformer architecture to process and generate both formats seamlessly.

Key Features of Goku

  • Industry-Leading Performance: Achieves 0.76 on GenEval, 83.65 on DPG-Bench for text-to-image tasks, and 84.85 on VBench for text-to-video tasks.
  • Unified Image-Video Generation: Uses a 3D Variational Autoencoder (VAE) to create a shared latent space for both images and videos.
  • Advanced Data Processing: Processes 160M image-text pairs and 36M video-text pairs using multimodal models.
  • Scalable Architecture: Available in 2B and 8B parameter configurations, optimized for high-quality generation.

2. The Architecture of Goku: How It Works

Goku’s core architecture revolves around three major components:

2.1 Image-Video Joint VAE

  • Inspired by Sora (OpenAI’s video model) and previous VAE-based diffusion models.
  • Compresses images and videos into a shared latent space, making it easier for Goku to generate both formats from a single model.

2.2 Transformer Model with Full Attention Mechanism

  • Unlike traditional Transformers that separate spatial and temporal attention, Goku applies full attention to both images and videos.
  • Uses FlashAttention and Sequence Parallelism for better memory management and efficiency.
  • Introduces 3D Rotary Position Embedding (RoPE) to handle varying resolutions and aspect ratios.

2.3 Rectified Flow-Based Learning

  • A novel training approach where the model learns a direct transformation between noise and the final output.
  • Faster convergence and improved stability compared to traditional Diffusion Models (DDPM).
  • Achieves lower FID (Frechet Inception Distance) scores than previous models.

3. Training Methodology: How Goku Learns

Goku undergoes a multi-stage training process to ensure optimal learning:

Stage 1: Text-Semantic Pairing

  • Pre-trained on text-to-image tasks to build an understanding of visual semantics.
  • Uses large language models (LLMs) like FLAN-T5 to enhance text-image alignment.

Stage 2: Image and Video Joint Learning

  • Integrates both images and videos into a unified training pipeline.
  • Uses cascaded resolution training, starting from low-resolution (288x512) and progressively moving to high-resolution (720x1280).

Stage 3: Modality-Specific Finetuning

  • Fine-tunes for image quality, motion consistency, and realism.
  • Enhances temporal smoothness and frame coherence in videos.

4. Data Processing: The Backbone of Goku

Goku’s strength lies in its extensive dataset, consisting of:

  • 160M Image-Text Pairs from LAION and proprietary datasets.
  • 36M Video-Text Pairs from sources like Panda-70M, InternVid, and OpenVid-1M.
  • Filtering and Captioning Pipelines:
    • OCR filtering removes excessive text overlays.
    • Motion filtering ensures smooth and natural video transitions.
    • AI-generated captions refine text-to-video alignment.
