什么是 ByteDance Seed Seaweed APT2?

ByteDance Seed's Seaweed APT2 is a research model for real-time interactive video: 'autoregressive adversarial post-training' turns a pretrained latent-diffusion model into a causal autoregressive generator that emits one latent frame (4 video frames) per single network forward pass, sustaining 24fps. It targets interactive use — real-time pose-driven virtual humans and camera-controlled world exploration — but as a research release it has no consumer API.

ByteDance Seed Seaweed APT2 能做什么

8B model that emits one latent frame (4 video frames) per single network forward pass (1NFE)
“Autoregressive adversarial post-training” turns a pretrained latent diffusion model into a causal autoregressive generator
Sustains 24fps real-time generation (research, 736×416 on a single H100, reported)
Zero-shot extension to multi-minute nonstop output (reported)
Aimed at interactive use: real-time pose-driven virtual humans and camera-controlled world exploration

ByteDance Seed Seaweed APT2 适合谁?

Following the research frontier of realtime interactive video generation
Exploring pose-driven virtual humans and explorable worlds, not just clip generation

ByteDance Seed Seaweed APT2 的优点与不足

优点

Pushes a clear research milestone: a latent frame per forward pass at 24fps
Long nonstop generation matters for live, continuous content
Open research release with a public project page

不足

Research-only — no consumer API or product as of Sep 2026
Speed figures are the authors’ own, on H100-class hardware
Not a tool you can deploy today without significant engineering
