La primera entrada es siempre la fuente del pin. La confianza global es una media ponderada de la firmeza con la que cada referencia respalda las horas de inicio y fin usadas arriba; una referencia cuenta la mitad por cada 180 días que sea más antigua que la más reciente.
La publicación de OpenAI[2][4][5] Developers en X tiene el sello del 12 de marzo de 2026 y el registro de cambios de la API de OpenAI enumera la misma entrada del 12 de marzo; AIBase[3] lo informó el 13 de marzo.
Mar 12 feature entry: reusable character references, generations up to 20 seconds, 1080p for sora-2-pro at $0.70 per second, video extensions and Batch API support for POST /v1/videos; a second entry adds /v1/videos/edits to replace remix.[1]
News write-up of the update: character consistency, 20 seconds up from a previous 12 or 16, video extension, and 16:9 and 9:16 exports; says nothing independent about quality.[1]
Records that on 24 March 2026 OpenAI[2][5] notified developers that the Videos API and all Sora 2 models would be removed on 24 September 2026.
Guide: sora-2-pro for 1080p exports in 1920x1080 or 1080x1920, 16 and 20 second generations on both models, input_reference images, and an edits endpoint replacing remix.[1]

Estimate from the version's published specs and reviews, 0-5; scores are only comparable within one criteria year. Scored as of 12 Mar 2026 (Sora 2 API update): sora-2-pro 1080p, up to 20 s per OpenAI's changelog, native audio, text and image input with reusable characters, video extensions and an edits endpoint, hence 3.5. Speed null: no published figure. Realism null: the only independent evaluation of this state is one DIY AI review (July 2026), which scored video quality 9.5/10 but also reported slow rendering; the quotes are therefore recorded without a consensus score.[1]
Video quality 9.5/10 The highest raw visual-quality score in the current dataset.
