True Sora cost = advertised rate ×3–7× due to revision cycles. Batch API's 50% discount worth planning around.

Summary
OpenAI discontinued Sora's consumer app on April 26, 2026, forcing users to the API—which itself sunsets September 24, 2026. A 10-second 1080p video costs ~$7 per generation, but the real expense lies in iteration cycles: each revision attempt costs the same as the original, multiplying budgets three to sevenfold for typical approval workflows. Batch API offers 50% discounts for non-urgent renders, reshaping cost models for creative teams with flexible timelines.
Key Points
- Sora API sunset scheduled Sept 24, 2026; consumer app already discontinued April 26
- 10-second 1080p costs $7 per gen, but approval revisions effectively multiply cost 3–7x
- Batch API applies 50% discount; off-peak rendering halves costs for flexible timelines
- ChatGPT Plus/Pro discontinued; shifted from flat-rate subscriptions to pure consumption pricing
- AI video market stratified: free hobbyist tools vs. enterprise custom agreements with SLA
View developer notes (APIs, breaking changes, migration)
Sora API uses per-second billing; 10-second 1080p generation costs ~$7. Batch API endpoint offers 50% discount for asynchronous renders, enabling off-peak scheduling. ChatGPT Plus ($20/mo) and Pro ($200/mo) subscriptions terminated April 26; both enforced rate limits (Plus: 5 req/min, Pro: higher). Sora API itself scheduled for termination September 24, 2026—no published successor documented. Iteration cycles multiply effective cost by 3–7x; forecast must account for approval revision cycles, not advertised unit rates alone.
