Real-Time AI Video: The AAPT Breakthrough for Live, Interactive Worlds

We dive into ByteDance Seed's AAPT—autoregressive adversarial post-training—that promises fast, frame-by-frame AI video for interactive experiences. Learn how a pre-trained diffusion model is converted into a causal, one-pass-per-frame generator, how KV caching and a sliding 5-second window keep latency in check, and why a three-stage training pipeline (diffusion adaptation, consistency distillation, and adversarial training with a frame-level discriminator) matters. We'll unpack student forcing versus teacher forcing, what the results say about latency, throughput, and long-horizon coherence, and what this could mean for real-time virtual worlds.
