  • OpenAI's deprecations page (announced 2026-03-24) lists this model for removal from the API on 2026-09-24 with no recommended replacement
  • the pricing page carries no deprecation notice, so the two vendor pages disagree - the deprecations page is the one that names a date. The higher-fidelity tier of OpenAI's Sora 2, using more compute per generation for sharper detail and stronger prompt adherence, with the same synchronized-audio text-to-video and image-to-video capabilities. Synthorai serves it via the async /v1/videos job API at 720p or 1024p, 24 fps, 4-12 s, 16:9 or 9:16, and bills per output second at a rate that rises with resolution

One prompt, one request per model, no retries and no cherry-picking - the first result each model returned. Neither size nor duration was pinned: each model used its own default, because a request shaped to fit all of them would flatter none. Files here are re-encoded for the web, so judge composition and prompt adherence, not compression.

About Sora 2 Pro

  • It spends more compute per generation for sharper detail and stronger prompt adherence, while keeping the same synchronized-audio, text-to-video and image-to-video capabilities.
  • OpenAI's guidance is explicit about the trade: Pro takes longer to render and costs more to run, but produces more polished, stable results, and it is the tier to choose when you need production-quality output rather than exploratory drafts.
  • Upstream it also offers an output size above the shared 720p pair - 1792x1024 landscape and 1024x1792 portrait - at a higher per-second rate.
  • Everything else matches the standard tier: reference images must match the target size and arrive as JPEG, PNG, or WebP, extension and edit flows are available for continuing or adjusting a finished clip, reusable characters keep a subject consistent with a limit of two per video, and the same content rules apply, with real people, faces in input images, and copyrighted characters or music all refused.
  • Synthorai serves it through the asynchronous /v1/videos job API at 720p or 1024p, 24 fps, 4 to 12 seconds, in 16:9 or 9:16, and bills per output second at a rate that rises with resolution, at a premium over the standard Sora 2.

FAQ

Is the Sora 2 Pro API free to try?

Yes: new accounts get 10 trial calls and up to $1 in free credit, no card required. That's enough to try Sora 2 Pro against your real workload before adding a payment method.

What is Sora 2 Pro best at?

Higher-fidelity Sora 2 tier, more compute per clip; sharper detail and prompt adherence; synchronized audio, 720p or 1024p, 4-12 seconds. See the About section for the full picture from the vendor's own release notes.

How much does Sora 2 Pro cost?

Sora 2 Pro costs $0.3-$0.5 per second of generated video on Synthorai. Only successful generations are billed: pay-as-you-go, no platform markup, no subscription.

How do I generate videos with the Sora 2 Pro API?

POST to /v1/videos on Synthorai with model="sora-2-pro" to create an asynchronous job, then poll the task (or hold the request open with a Prefer: wait header) until the video URL is ready. No vendor SDK is needed.

How do I get access to Sora 2 Pro?

Point your existing OpenAI SDK at base_url="https://synthorai.io/v1", set model="sora-2-pro", and you're done. One API key covers every model on the gateway.
