Sora (OpenAI)
OpenAI is winding Sora down. The API is scheduled for removal in September 2026.
OpenAI discontinued the Sora 2 web and app experiences in April 2026, with the API slated for removal in September 2026. Industry analysis indicates that Sora 2's 'physics-first' approach was computationally expensive and led to high failure rates in audio generation (reportedly 75%). For new video pipelines we recommend Veo 3.1 (cinematic quality + native audio) or Kling 3.0 (long-form social, ~10x cheaper per second).
Provider winding down

Use Cases
Migration to Veo 3.1
For ongoing pipelines using Sora — Nagent's migration tooling re-points workflows at Veo 3.1 with one config change.
Migration to Kling 3.0
For social-video workloads where cost matters more than 4K — Kling 3.0 produces longer clips at roughly 10% the per-second price of Veo.
Fallback for Existing Workflows
Sora API still available through September 2026 — keep using it for in-flight projects while you migrate.

Common questions about Sora (OpenAI)
Real buyer and developer questions, answered. Click any item to expand.
Why is OpenAI shutting down Sora?
OpenAI hasn't published a definitive reason. Industry analysis points to the "physics-first" approach being computationally expensive, with high audio failure rates (reportedly ~75%). Veo 3.1's joint audio/video architecture proved superior on both cost and quality.
Should I migrate now or wait until September 2026?
Migrate now if you have ongoing pipelines. Nagent's migration wizard re-points workflows to Veo 3.1 or Kling 3.0 in one config change. Waiting risks last-minute pressure when the API actually shuts off.
Is Veo 3.1 a true replacement for Sora?
Yes for cinematic quality and joint audio. For social and short-form video, Kling 3.0 is actually a better fit — multi-shot narrative control plus roughly 10× cheaper per second. Pick based on use case, not as a 1:1 swap.
