Open-Sora 2.0 Scales to 11B Parameters in a Dense Open-Weight Video Release Window

AI Free Forever·low signal

Open-Sora 2.0 scaled up to 11 billion parameters, landing alongside Wan 2.7 in one of the densest open-weight video-generation windows on record. The size bump targets higher fidelity and longer coherent generations from a fully open, self-hostable text-to-video stack. For builders, it strengthens the open video tier as a credible alternative to closed video APIs for experimentation and pipelines that can't send footage to a vendor.
