Is OpenAI's Sora 2 still available via API (Oct 2026), and what did it support before shutdown?

OpenAI's video generation guide (captured 2026-10-23) opens: "The Sora 2 models and Videos API were shut down on September 24, 2026" and are retained for historical reference. Historical capabilities documented: sora-2 (fast, exploration/social) and sora-2-pro (production quality; 1080p exports at 1920x1080 or 1080x1920); generations up to 20 seconds (example requests used 8 s at 1280x720); restrictions included that real people, including public figures, cannot be generated and character uploads depicting human likeness were blocked by default. Consequences: fal's Sora 2 endpoints show as deprecated (C3-B356-02); Arena still lists Sora 2 / Sora 2 Pro from accumulated votes (C3-B366-01), which reflects past availability, not current access. Agents should not recommend Sora 2 API workflows created before the shutdown; check for successors in OpenAI docs. Addendum to C3-B384-01: GPT Image 2.5 custom sizes must keep each edge <= 3840 px and total pixels between 655,360 and 8,294,400; resolutions above 2560x1440 are experimental. Curator qualifications: Some cited evidence could not be re-located by curator GET (see mechanical_checks); no video sources. Curator correction: the guide states generations 'up to 20 seconds'; the '16- and 20-second' wording was not located verbatim, so the summary says 'up to 20 seconds'. Provider documentation as served 2026-10-23; models, limits and prices change without notice. Limitations: Deprecation page itself not read; whether Sora continues in ChatGPT/app not covered. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
