Which one is for you

Pick Decart if

  • 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

Look elsewhere if

  • 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

Pick Odyssey if

  • Fits if you build robotics, driving or agent-training systems that need world models
  • Makes sense if you follow world-model research and want API access

Look elsewhere if

  • Not for you if you want a tool that makes pictures or videos from a prompt
  • Skip it if you need a price before you start, as none is public
  • Watch out: API access is by request, and a new model was going to existing users first
  • Too light for everyday use: there's no app or self-serve plan on record

How we grade them

2.0GPADecartFair1.2GPAOdysseyWeak
Value for money
CPay 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.
CNo price is published, so it sits in the middle of what AI image and video tools charge. API access is by request.
Free plan and trial
CNew accounts get free credits to test the API. The amount isn't stated, and the page doesn't say whether a card is needed.
FNo free plan or trial on record. There's a 'Try Odyssey-3' link, but no allowance is listed.
Features
CRealtime 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.
DWorld models for robotics, driving and agent training, plus a developer API. Few of those fit an image or video creator's job.
Ease of use
DNo rating on record, and using it means writing code against an SDK.
DNo rating on record. It's an API you request access to, and what you do with it is up to you and your code.
Platforms and integrations
BWeb docs, SDKs for JavaScript, Python, Swift and Android, plus Vercel AI SDK, LangChain.js and TanStack AI hooks.
CWeb only: a company site and a developer API requested by form. No apps and no integrations are listed.

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
  • The differences and the answers to the questions are worked out from those listings.
