What's New

Unified multimodal context (not a pure t2v silo).
Native stereo audio without a separate audio stage.
Open weights = H3-Base only; Context-IR and 2K regenerate stay closed/API-side.

Caveats

Community license: territory excludes EU/UK/KR/US for weights; ≥$20M needs prior auth; no training other models on outputs. Read before commercial use.
Open weights = H3-Base only; Context-IR and 2K regenerate stay closed/hosted.
Don't invent exact 2K WxH from marketing.
H3 not on video subscription packages yet (paygo).
