Sora 2: What It Was, What It Cost, and What To Use Now That OpenAI Is Retiring It

What Sora 2 actually is

Sora 2 is OpenAI's text-to-video model. It launched publicly on September 30, 2025, about a year after OpenAI stopped demoing the original Sora and started training the next version.

The model generates short clips from text prompts or reference images. You type what you want, you wait, and you get a video file back with audio baked into the same generation pass.

The audio sync is the thing that separates Sora 2 from what came before. Most earlier video models, including Sora 1, gave you silent footage. You matched sound in post. Sora 2 generates the dialogue with lip movements that match the words, ambient sound that changes based on distance and scene context, and sound effects time-aligned to whatever's happening on screen. All in one call.

The other headline is physics. Sora 2 holds multi-subject scenes together better than any OpenAI model before it. Falling objects land where they should. Fluid behaves like fluid.

Two characters in the same shot maintain their spatial relationships through motion. That's a real jump from Sora 1, which routinely garbled the physics of anything with more than one moving subject.

Resolution tops out at 720p on Sora 2 and 1080p on Sora 2 Pro. Both take clips up to 20 seconds.

So what Sora 2 offered was cinematic coherence, native audio, and a generous clip length. What it never offered was 4K, multi-model flexibility, or a workflow with a future. The next section covers what happened to it.

The access story: OpenAI is retiring Sora 2

Sora 2 is being retired, in two steps.

The consumer product went first. OpenAI's help center records that the Sora app and web experience shut down on April 26, 2026, and the current ChatGPT Plus and Pro plan pages no longer list Sora as a benefit. If you subscribed to ChatGPT to make video, that path is gone.

The API is next. The same notice schedules the Sora 2 API for removal on September 24, 2026. Until that date the developer rates hold: $0.10 per second for Sora 2 at 720p, and $0.30 per second at 720p, $0.50 at 1024p and $0.70 at 1080p for Sora 2 Pro, with batch rates at half of each.

So the honest cost of Sora 2 today is not a number. It is a deadline. Anything built on it needs a replacement model before the end of September 2026, and any per-clip math you do against its rates is math about a product that stops answering.

How Sora 2 compares to what Slates actually runs

Slates never ran Sora 2, and with the API scheduled for removal it never will. What Slates does run are three video models that cover overlapping parts of the Sora 2 use case, on providers that are shipping rather than retiring.

Seedance 2.0 is the closest match for the audio plus video use case. ByteDance built Seedance with synced audio as a first-class feature, and every clip ships with dialogue, ambient sound, and effects baked into the same generation pass, at no extra cost. Clip length is 4 to 15 seconds, and resolution runs from 480p all the way to 4K rather than stopping at Sora 2's 720p ceiling.

At 720p the provider rate is $0.15 per second, so Seedance is not the cheaper option against Sora 2's $0.10. What you get for the difference is a model that is not being switched off, no subscription, and a resolution ladder that keeps going. The real gap is the realistic-human face filter ByteDance added after legal pressure from the major studios, which blocks face references that Sora 2 handles fine.

Kling 3.0 is the closest match for cinematic camera work. Kling understands real cinematography vocabulary in its prompt parser (pan, tilt, dolly, zoom, truck, roll) and executes those instructions instead of treating them as decoration. Its censorship floor is lower than both Sora 2 and Seedance, so fashion, music video, and editorial work that Sora 2 sometimes rejects goes through. It runs at 1080p for everyday work with 4K available for hero shots, and audio is an option you pay for rather than something baked into every clip.

Veo 3.1 is the cheapest native 4K of the three. If resolution is the reason you wanted Sora 2 Pro, Veo 3.1 Standard at 4K beats Sora 2 Pro at 1080p on every pixel-count metric, and at $0.40 per second with audio off it undercuts Sora 2 Pro 1080p's $0.70. Veo's content filter is aggressive, so anything Google's Imagen would reject gets rejected here too.

None of these is a pixel-for-pixel Sora 2 clone. Between the three, Slates covers every use case Sora 2 was good for, on models with a road ahead of them.

What to do if Sora 2 was on your list

If you have Sora 2 clips in a pipeline, the API keeps answering until September 24, 2026. Export what you need before then; there is no consumer path left to fall back on.

If you were evaluating Sora 2, evaluate its replacements instead. Slates runs Kling 3.0, Veo 3.1, and Seedance 2.0 as a single desktop app with per-credit pricing. You pay for the seconds you actually generate, and you pick the model per shot.

For the Sora 2 audio-first use case, Seedance 2.0 is the cleanest match, at $0.15 per second for 720p against Sora 2's $0.10. For cinematic camera work without audio, Kling 3.0 Standard undercuts both at $0.084 per second. For 4K hero shots, Veo 3.1 Standard beats Sora 2 Pro on resolution at a lower per-second cost than Pro's 1080p rate.

The real question was never one flagship model against three. It is whether the model you build on will still be there next quarter.
