Sora 2 vs Kling 3.0
These two never price the same render: Sora 2 sells clips of 4s, 8s and 12s and Kling 3.0 sells 5s, 10s and 15s, so there is no like-for-like row to put them on and any straight price comparison would be comparing different products. They do both price 1080p, though, and a second of 1080p is a second of 1080p whichever model made it, so the comparison that does hold is credits per second at the same resolution: 1080p is 20 credits a second on Sora 2 against 52 on Kling 3.0. Sora 2 is the better rate at the one resolution they share. Those are each model's best rate at that resolution, taken from the tables below. In practice, take Sora 2 if you want to render from a written prompt with nothing else to hand, and Kling 3.0 if you need one continuous clip longer than 12 seconds.
We run Sora 2 (OpenAI) and Kling 3.0 (Kuaishou) ourselves, on our own provider accounts, inside the same studio and off the same credit balance. Everything below is read out of the catalogue that prices your renders, so the numbers are the ones your account is actually charged. What you will not find here is a quality verdict: we hold no benchmark that would make one honest, so every claim on this page is a capability or a price you can check.
Sora 2 vs Kling 3.0: the specs
Every cell below is read from the catalogue that our generator and our billing run on, so it is what you get and what you are charged, not what a vendor page advertises. Two rows are worth reading carefully: where the render runsis the platform we actually dispatch to, which is not always the one a model’s Replicate name implies, and how the length is set separates the models you give a duration to from the ones whose clip runs as long as the speech does.

Cost: compared per second, not per render
Sora 2 and Kling 3.0 do not sell a single clip length and resolution in common. Sora 2 is priced at 4s, 8s and 12s, Kling 3.0 at 5s, 10s and 15s. Putting a 4s render next to a 5s one and calling the gap a price difference would be comparing two different products.
What they do have in common is resolution. Both price 1080p, and a second of 1080p is a second of 1080pwhichever model made it. So the honest unit here is credits per second at the same resolution, taken from each model’s best tier at that resolution.
| Resolution | Sora 2 | Kling 3.0 | Difference |
|---|---|---|---|
| 1080p | 20 credits/sec best on 4s at 1080p, 80 credits | 52 credits/sec best on 5s at 1080p, 260 credits | 32 credits a second cheaper on Sora 2 |
Multiply a row by the length you actually need and you have the comparison this page cannot make for you. At those rates ten seconds of 1080p works out at roughly 200 credits of Sora 2 against 520 of Kling 3.0, before you round up to the lengths each one actually sells (4s, 8s and 12s; 5s, 10s and 15s).

Credit costs, not dollars: what a credit costs you depends on the plan, and all three plans are listed on the pricing page.
Which one to pick
Each line below traces back to a single difference in the tables above. Where a model has no measurable advantage, that is what it says.
Pick Sora 2 if
- You want to render from a written prompt with nothing else to handSora 2 does not require a reference image. Kling 3.0 does, so you need a product shot or an avatar frame before you can render at all.
- You want the cheapest possible render to test an idea onSora 2 starts at 80 credits (4s at 1080p). The cheapest thing Kling 3.0 sells is 210 credits.
- You are buying seconds of finished video rather than a specific clip lengthSora 2 is the better rate at every resolution the two share (1080p): 20 credits a second against 52 at 1080p.
Pick Kling 3.0 if
- You need one continuous clip longer than 12 secondsKling 3.0 runs to 15s in a single call. Sora 2 caps at 12s, so anything longer has to be cut together from more than one render.
- The deliverable has to be 4KKling 3.0 prices a 4K tier, from 390 credits for 5s at 4K. Sora 2 tops out at 1080p.
- One shot has to combine several things you already have, a product, a face, a backgroundKling 3.0 carries up to 7 reference images into a single render. Sora 2 carries one, so the rest has to come from the prompt.
- You are standardising a workflow you expect to still be running next quarterSora 2 carries a vendor-announced end date of 24 September 2026. Kling 3.0 has none.
What they have in common
A comparison that manufactures a difference is worse than no comparison, so here is where Sora 2 and Kling 3.0 genuinely match.
- Both come back with their own audio, so neither needs a separate voice pass in the chain.
- Both price 1080p.
- Both are dispatched to Replicate from our own account, Sora 2 as openai/sora-2 and Kling 3.0 as kwaivgi/kling-v3-omni-video.
- Both spend from that one balance on every plan, so moving a campaign from Sora 2 (from 80 credits a render) to Kling 3.0 (from 210) costs you nothing but the credit difference.

One credit balance, every model
Sora 2 and Kling 3.0both spend from the same balance, so a plan is not a commitment to one of them. Here is what each plan’s credits buy on the two models on this page, measured in seconds of finished video.
| Plan | Credits a month | Sora 2 | Kling 3.0 |
|---|---|---|---|
| Starter $49 a month, or $34 billed annually | 5,000 | 245 to 250 seconds | 64 to 120 seconds |
| Growth $99 a month, or $69 billed annually | 12,000 | 588 to 600 seconds | 153 to 289 seconds |
| Agency $199 a month, or $139 billed annually | 25,000 | 1,225 to 1,250 seconds | 320 to 602 seconds |
The low end of each range is the model’s dearest priced tier and the high end its cheapest, both from the tables above, so a month spent entirely at 4K sits at the bottom and a month of 720p drafts near the top. Mixing models moves it in between. On a paid plan, credits are the only limit: no cap on how many renders you make and no per-model licence. Annual billing is 30% off (Starter saves $180 a year, Agency $720). Both need a paid plan: neither is available inside the free 3-day trial, which covers the rest of the catalogue instead.
Sora 2 vs Kling 3.0: frequently asked questions
Which is cheaper, Sora 2 or Kling 3.0?
These two never price the same render: Sora 2 sells clips of 4s, 8s and 12s and Kling 3.0 sells 5s, 10s and 15s, so there is no like-for-like row to put them on and any straight price comparison would be comparing different products. They do both price 1080p, though, and a second of 1080p is a second of 1080p whichever model made it, so the comparison that does hold is credits per second at the same resolution: 1080p is 20 credits a second on Sora 2 against 52 on Kling 3.0. Sora 2 is the better rate at the one resolution they share. Those are each model's best rate at that resolution, taken from the tables below.
Can Sora 2 and Kling 3.0 render the same clip?
Not at the same length. Sora 2 sells 4s, 8s and 12s and Kling 3.0 sells 5s, 10s and 15s, and there is no length both price, so a Sora 2 render and a Kling 3.0 render are never the same product. What they do share is resolution: both price 1080p. Per second of finished video that works out at 20 against 52 credits at 1080p. Multiply by the length you actually need and you have the real comparison.
How long can a single Sora 2 or Kling 3.0 clip be?
Sora 2 caps at 12s and prices 4s, 8s and 12s. Kling 3.0 caps at 15s and prices 5s, 10s and 15s. Both are per-render limits, so a longer ad is several renders cut together rather than one long generation.
What resolutions do Sora 2 and Kling 3.0 render at?
Sora 2 is priced at 1080p. Kling 3.0 is priced at 720p, 1080p and 4K. Those are the tiers you can actually buy, not the tiers the vendors advertise.
How many reference images can Sora 2 and Kling 3.0 take?
Kling 3.0 carries up to 7 reference images into one render and Sora 2 carries one. That matters when a shot has to combine things you already have, a product, a hand, a background, in the same frame: with one image the rest has to be described in the prompt and re-rolled until it lands. The counts are read from the request each model is actually sent, not from a vendor spec sheet.
Do Sora 2 and Kling 3.0 need a reference image?
Kling 3.0 does and Sora 2 does not. Sora 2 will render from a written prompt on its own.
How do Sora 2 and Kling 3.0 handle audio?
The same way. Sora 2 generates its audio in the same pass as the picture, so there is no separate voice step to run or pay for, and Kling 3.0 works identically. Neither one needs a voice model bolted on afterwards.
Is Sora 2 being retired?
Yes. Sora 2 carries a vendor-announced end date of 24 September 2026, and Kling 3.0 has none, which is the one asymmetry on this page that a price table will not show you. If you are picking between them for something that has to keep running past that date, Kling 3.0 is the side that survives it. Kling 3.0 caps at 15s and prices 5s, 10s and 15s, at 720p, 1080p and 4K, from 210 credits. We publish the date because standardising an ad workflow on an endpoint that disappears is an expensive surprise, and this comparison stops generating once it passes.
Do I need a separate plan for each model?
No. Every plan is one credit balance that spends on any model we run, so the same subscription renders a Sora 2 test at 80 credits and a Kling 3.0 test at 210 and you compare them on your own footage. There is no per-model licence, and on a paid plan credits are the only thing that runs out rather than a render count.
Can I try Sora 2 and Kling 3.0 on the free trial?
Neither, and it is better to know that here than at the Generate button. Sora 2 and Kling 3.0 both need a paid plan: the trial does not carry either of them. The trial does cover the rest of the catalogue, so it is still the cheapest way to see the studio itself.
Where do these Sora 2 and Kling 3.0 numbers come from?
From the accounts the renders actually run on. Sora 2 is dispatched to Replicate as openai/sora-2 and Kling 3.0 to Replicate as kwaivgi/kling-v3-omni-video, both ours. The 3 priced tiers listed for Sora 2 and the 9 priced tiers for Kling 3.0 are read at build time from the same price table that debits your balance when a render finishes, and the capabilities come from the record the generator reads to build each request, so a reprice or a new tier rewrites this page instead of leaving a stale number on it. What you will not find is a quality or realism score for either one: we hold no benchmark that would make one honest.
