FLUX 3 is a single multimodal family (video, image, action). This entry is its video generation only, and FLUX 3 Image is separate. releaseDate is the Jul 23, 2026 announcement, which opened FLUX 3 Video in Early Access (AA lists 'Jul 2026'). General availability via the BFL API and partners was announced Aug 4, 2026 (bfl.ai/blog/flux-3-video). The docs still say 'FLUX 3 is a preview model'. Audio is on by default and can be disabled. Duration is 5 to 20 s or auto. The blog's own internal Elo chart lists FLUX 3 T2V at 1135, which is not used. AA silent board: 1091 (#5). LMArena score is the preliminary 'flux-3-video' row (#3) from the board dated Sep 21, 2026. The blog mentions video-to-video generation from a reference clip, and editing ships as a separate product (FLUX Video Edit [fast], /v1/flux-tools/video-edit-v1, $0.03/s), so 'video-editing' is not claimed. fal ids come from fal's own model pages. fal also has first-last-frame-to-video, keyframes-to-video, /draft twins and draft-enhance endpoints.
