ByteDance has unveiled Seaweed-7B, a 7-billion-parameter AI video generation model that delivers high-quality, real-time video with synchronized audio, rivaling larger models like OpenAI’s Sora and Google’s Veo at a fraction of the compute cost. Seaweed-7B supports text-to-video, image-to-video, and audio-driven synthesis, producing up to 60-second 720p videos at 24fps in real-time. It features advanced capabilities such as multi-shot storytelling, precise camera control, and lifelike human motion with synchronized lip-sync. The model’s efficiency stems from innovations like a 64× compression VAE, hybrid-flow Transformer architecture, and a progressive training strategy, reducing training costs by two-thirds compared to similar models. Seaweed-7B is currently in closed testing, with potential applications in AI filmmaking, education, gaming, and virtual assistants.
