The text-to-video board of the Artificial Analysis Video Arena: people watch two clips, pick the better one without knowing which model made it, and the votes give an Elo score. The rank is the model's place in the board's default view (current models), and names are written as the board writes them; checked Sep 26, 2026. Scores move every week and are a guide to quality only. See the leaderboard ↗

How the status is checked
Whether a model still runs is checked separately from prices: prices change monthly, but a model can disappear between two price syncs, quietly making every page that mentions it wrong. So each model record has its own confirmation date and review deadline; overdue records are flagged, never assumed to still be running.
Last confirmed on Sep 26, 2026; due to be rechecked by Oct 26, 2026.
