Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 31 of the 168 other AI image and video generators we grade
Decart is an AI lab that builds real-time video models, including Lucy for live video editing and Oasis for interactive world generation, plus software to speed up model inference. Its API platform bills per second or per generation with no subscription. New accounts get free credits to test it.
To get you started, here are 8 things to know about Decart, taken from its own pages and our grades.
No rating on record, and using it means writing code against an SDK.
- 1
Best for real-time video models through an API
It's a product for developers, not a finished video app.
- 2
You can try it first
New accounts receive free credits to test the API before paying.
- 3
It runs on Web
Web.
- 4
Real-time video editing
Lucy edits a live video stream with text prompts or reference images, at 30 FPS for Lucy 2.5.
- 5
Virtual try-on
Lucy VTON models handle realtime virtual try-on.
- 6
Oasis world model
Oasis generates interactive worlds that respond to actions in real time.
- 7
A 2.0 GPA, above 31 of 168
That is against the other AI image and video generators we grade, on value, the free plan, features, ease of use and platforms.
- 8
Keep it
To replace Decart you would be making a video model, which you can rent by the second but not make. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for real-time video models through an API
Decart is an AI lab with real-time video models like Lucy for live editing and Oasis for interactive worlds, sold through an API with no subscription. Realtime editing is $0.02 a second, or $0.04 in fast mode, and new accounts get free credits to try. It's a product for developers, not a finished video app.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Pay as you go with no plan and no minimum: $0.02 a second for realtime Lucy 2.6, $0.04 for video editing. There's no monthly figure to set against the category, so it sits in the middle. |
| Free plan and trial | C | New accounts get free credits to test the API. The amount isn't stated, and the page doesn't say whether a card is needed. |
| Features | C | Realtime video editing, virtual try-on, video and image editing and the Oasis world model, which is still a preview. Each is an API model, not a ready-made tool. |
| Ease of use | D | No rating on record, and using it means writing code against an SDK. |
| Platforms and integrations | B | Web docs, SDKs for JavaScript, Python, Swift and Android, plus Vercel AI SDK, LangChain.js and TanStack AI hooks. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Decart is for
- Fits if you're a developer adding live video effects to an app
- Makes sense if you'd rather pay per second than take a subscription
Who it is not for
- Not for you if you want a video app, as using it takes code
- Watch out: realtime fast mode is $0.04 a second, double the base rate
- Watch out: Oasis 3 is a preview, and enterprise pricing is by contacting them
- Skip it if you need a free allowance you can count on, as the credit amount isn't stated
Good to know
Good for
- Developers building live video effects into apps and streams
- Teams working on virtual try-on or live commerce
Worth knowing
- Billing is pay as you go with no subscription: realtime Lucy 2.6 is $0.02 a second, or $0.04 in fast mode.
- Video editing with Lucy 2.6 at 720p is $0.04 per generated second; Lucy Image 2 is $0.01 to $0.02 per image.
- It is an API and research product, not a ready-made video app, so using it takes code.
- Oasis 3 is a preview, with enterprise pricing offered by contacting the company.
Part 02 · Pricing
What it costs
Every plan, the free plan, ways to pay less and how prices have moved

Its grades against its category, and whether to keep it or make your own
31/168
Other AI image and video generators it is graded above
Decart's GPA of 2.0 is higher than 31 of the 168 other AI image and video generators we grade, and level with 31.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Decart you would be making a video model, which you can rent by the second but not make. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 106 of the 168 other AI image and video generators grade higher.
What you could not
- A video model, which you can rent by the second but not make.
- An image model, which you can rent by the picture but not make.
- It plugs into other products, Vercel AI SDK, LangChain.js and TanStack AI among them, and has an API.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. Decart’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
