The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
The OpenAI[2][4][5] Developers post on X is stamped 12 March 2026 and OpenAI's API changelog lists the same Mar 12 entry; AIBase[3] reported it on 13 March.
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]
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.
