Researchers have developed a novel method for real-time joint audio-video generation using a diffusion transformer. This approach utilizes parallel adapter composition, combining a causal adapter for streaming video with an off-the-shelf few-step adapter. The parallel training strategy ensures that the two adapters' weight updates are orthogonal, preventing interference and allowing them to be simply added at inference time. The resulting system achieves real-time generation speeds of approximately 26 frames per second at a resolution of 480x832, maintaining stable image quality for extended periods. AI
