Meta
Meta builds its generative video models in-house under Meta Superintelligence Labs’ Muse family, after years of licensing outside image and video models. Muse Video previewed in July 2026 and debuted at #3 on Design Arena’s text-to-video board; Muse Realtime Avatar followed in September, a real-time avatar system Meta benchmarked by name against Runway Characters and HeyGen LiveAvatar in its own rater study.
