Video model rubric2026 criteria

Estimate from the version's published specs and reviews, 0-5; scores are only comparable within one criteria year. Scored as launched (15 Oct 2025, Veo 3.1 and 3.1 Fast): 720p and 1080p output (4K upscaling came in Jan 2026, so not scored), 8-second clips that Extend chains beyond a minute (single generation stays 8 s), richer native audio, text plus up to 3 reference images, first and last frame, extension and insert (no video or audio references, so 3.5 not 4). No render time is published. Realism: Tom's Guide picks Sora 2 overall and flags repeated subjects and extra limbs; the AI Filmmaker likes the more human voices but sees more random cuts; Motion The Agency finds it more stable than Veo 3; Artificial Analysis's current arena ranks Veo 3.1 21st at Elo 963, a later board that mixes newer rivals, so the score is a middling 3.5.^[1]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
