}Evidence claims
- [upstream_claim] README: video generated in fixed-length chunks, next chunk starts when the current is partly denoised (up to four chunks in flight); supports T2V, I2V, V2V; sizes 24B and 4.5B with distilled/quantized variants; MAGI-1.1-24B weights open-sourced on 2026-06-17. source
- [upstream_claim] Hardware per README: 24B needs 8x H100/H800 (or 4x H100 / 8x RTX 4090 for distilled+quantized); 4.5B runs on one RTX 4090 or any >= 24 GB GPU; distilled+quant 4.5B about 12 GB with window_size 1. source
- [upstream_claim] HF card lists Apache-2.0; its model table marks 4.5B distill variants 'coming soon' while the news section says they were released 2025-05-26 (internal inconsistency). source
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
