What is Magi-1?

Magi-1 (Sand AI) is a 24B autoregressive video diffusion model: instead of generating a fixed-length clip in one pass, it produces frames sequentially with kv-cache reuse. Result: arbitrary-length generation and tight prompt consistency across long shots — a different value prop than Wan/Hunyuan.

Pros & cons

Pros

  • Arbitrary-length generation, not capped at 5–8 seconds
  • Strong temporal consistency through autoregressive sampling
  • Apache 2.0 — fully commercial-friendly

Cons

  • 24B parameters — 24 GB minimum, 48 GB comfortable
  • Autoregressive sampling is slower per second of output than full-clip diffusion
  • Younger ecosystem than Wan/Hunyuan

What's actually free?

Apache 2.0; weights free.
