Details

The newly unveiled FLUX 3 is a multimodal foundation model that jointly trains on images, video, and audio within a single architecture. Beyond simply learning individual modalities, it aims to learn a 'representation of the world'—including how objects move, the causal relationships of sound, and physical laws.

FLUX 3 is built on Self-Flow technology, which efficiently aligns multimodal generation and understanding. Compared to the existing Flow Matching (FM) approach, it shows higher generation efficiency and a higher success rate on manipulation tasks.

Key features are as follows:

  • Unified architecture: A single model handles the spatial structure of images, the temporal dynamics of video, and the causal relationships of audio.
  • Physical intelligence: By combining sound and motion, and the relationship between past and future, it gains the ability to predict and understand real physical environments.
  • Scalability: The model was trained simultaneously on video, image, and audio using large-scale compute and data resources.
