When does the Sora API shut down?

September 24, 2026. That date is confirmed. If you have production workloads on Sora endpoints, you need a migration completed before then.

No. OpenAI has not announced a Sora 3. After shutting down Sora 2, the company said it is repurposing Sora as a world-model research effort — with no successor product, API, or timeline on the roadmap. Treat any 'Sora 3' claim carrying dated specs as speculation.

What's the best Sora API alternative?

It depends on your workload. For the lowest per-clip cost with multi-modal control, Seedance (via Volcano Engine, kie.ai, or fal.ai). For narrative multi-shot content, Kling 3.0. For maximum quality with native audio and a bigger budget, Veo 3.1 via the Gemini API.

Will my Sora prompts work on other models?

Mostly, with adjustment. Prompt styles transfer, but each model has its own strengths, keywords, and reference-input systems. Budget a day of prompt migration testing rather than expecting drop-in compatibility.

Sora 3, the API shutdown, and where developers should migrate

Updated July 22, 2026

RetiringThe Sora 2 app is already gone and the API shuts down September 24, 2026. There is no announced Sora 3 — OpenAI has pivoted Sora to research. If you build on Sora, migration is the only real plan.

The Sora wind-down, in order

Sora 2 app & sora.com — went offline April 26, 2026.
Sora 2 API (sora-2, sora-2-pro) — confirmed shutdown on September 24, 2026. After this date, endpoints stop working.
Sora 3 — not announced. OpenAI is repurposing Sora as a world-model research effort; no successor product, API, or timeline exists.

No successor announced

Earlier "Sora 3 inside ChatGPT" reporting never materialized: OpenAI shut Sora 2 down and framed the pivot as world-model research, with no replacement product or API. Betting your roadmap on a Sora comeback is risky — plan the migration.

Migration options compared

If you're running production video generation on Sora endpoints, these are the three realistic paths:

	Seedance 2.0	Kling 3.0	Veo 3.1
Best for	Cost-sensitive volume, multi-modal control	Narrative multi-shot content	Maximum quality, physics, native audio
API access	Volcano Engine / BytePlus, kie.ai, fal.ai	Kling API, aggregators	Gemini API / Vertex AI
Relative cost per clip	Lowest	Middle	Highest
Watch out for	Global API access has paused before (copyright disputes)	Storyboard style differs from Sora's single-take feel	Premium pricing at volume

Timing note: Seedance 2.5 is expected around late July–early August. If your shutdown deadline is September 24, you may be able to migrate directly onto the newer model instead of 2.0 — same API channels, better output.

A realistic migration plan

Now: shortlist two models and run your top 20 production prompts on both (a few dollars of API credit).
By late August: port prompt templates and reference-input handling; the input APIs differ meaningfully.
By September 10:cut over with two weeks of margin. Don't discover an edge case on shutdown day.
