What is Odyssey-2?
Odyssey-2 is a world model from Odyssey, an AI lab. Rather than planning a whole clip at once, it predicts each frame from the ones before, so it can react while it plays: you type a scene, a stream starts, and each new prompt changes what happens next. Odyssey says most video models take a minute or two to make five seconds of footage; Odyssey-2 makes a frame every 50 milliseconds.
It has since been replaced. Odyssey-2 Pro, a larger model streaming 720p at 22 frames a second, launched Odyssey's API, followed by Odyssey-2 Max and Odyssey-3. The free web demo is the only public way to try it.
Is Odyssey-2 still available?
Only as a free web demo. Odyssey has moved on to newer models, and its API launched with Odyssey-2 Pro instead.
- Web demo
- Free in the browser with no sign-in; it still opens with a clip titled Meet Odyssey-2.
- Odyssey-2 Pro
- The larger successor, streaming 720p at 22 frames a second, and the first model in Odyssey's API.
- Odyssey-2 Max
- About three times the size of Pro, in private beta for partners and rolling out to existing API customers.
- Odyssey-3
- A foundation world model aimed at robots, cars, drones and games, which Odyssey says it will release publicly soon.
Who is Odyssey-2 best for?
Odyssey-2 is best for anyone curious to see live, steerable AI video in a browser, and for teams sizing up Odyssey before asking for access to its newer models.
A first look at world models
The browser demo shows how live, steerable AI video feels, with no account, install or payment.
Quick, playful scenes
Typing a change into a running scene, such as making a dog stand up or starting rain, takes no skill and shows up within moments.
Teams scouting Odyssey
It is a free way to judge Odyssey's approach before asking for API access to Odyssey-2 Pro or Max.
What's included with Odyssey-2?
Text prompts that change the video as it plays, image starts, a new frame every 50 milliseconds, minutes-long streams and a free browser demo.
- Live text steering
- Type a new instruction while the video plays and the stream changes course without starting over.
- Start from an image
- The web demo also lets you upload a picture and begin the stream from it instead of a text prompt.
- Frame-by-frame generation
- Each frame is predicted only from earlier frames and your input, which is what lets it react in real time.
- Minutes-long streams
- A stream keeps running for minutes rather than ending after a fixed clip length.
- Browser demo
- Runs in Odyssey's web demo with a short queue and a play-time countdown; an email sign-up adds 20% more play time.
How much does Odyssey-2 cost?
Odyssey-2 is free to try in Odyssey's web demo with no sign-in, and Odyssey publishes no prices for its API, which serves the newer Odyssey-2 Pro and Max by request.
- No sign-in or payment needed
- Play time runs on a countdown of about 8 minutes
- An email sign-up adds 20% more play time
Odyssey publishes no prices and has no pricing page. Its API launched with Odyssey-2 Pro, and Odyssey-2 Max is rolling out to existing API customers; new developers request access through a form. API fees are set in a contract and billed monthly in advance. Full pricing on experience.odyssey.ml. We checked these prices on .

Odyssey-2 pros and cons
It reacts to typed changes within moments and costs nothing to try, but it has been replaced, has no public API or prices, and you cannot move through the world yourself.
Pros
- Reacts fast: early users say typed changes, like making a dog stand up or making it rain, show up in the stream within moments.
- Streams at once instead of making you wait: a new frame every 50 milliseconds, where Odyssey says most video models need a minute or two for five seconds.
- Free to try in a browser with no account, install or payment.
Cons
- Replaced: Odyssey-2 Pro took over as the model in Odyssey's API, and Odyssey-2 Max and Odyssey-3 have followed.
- No public prices or self-serve API; new developers must request access, and fees are set by contract.
- You direct it with typed prompts, not movement controls: one early user noted you cannot walk through the world as in Odyssey-1, and another called it a step away from a playable world.
- Weaker physics than its successors on Odyssey's own tests: 48.58 on VBench 2's physics measure against 58.52 for Odyssey-2 Max.
What are the best Odyssey-2 alternatives?
MiniMax H3 Max for live video you can build on, World Labs Marble for 3D worlds you can walk through, and Lucy 2.5 for real-time edits of live video.
MiniMax H3 MaxFreeChoose it when you want live, prompt-steered video you can build on now; its Director endpoint is open to any fal account at $0.08 a second, in sessions of up to 15 minutes.

Lucy 2.5FreemiumChoose it when you want to transform live camera video in real time rather than imagine a scene; Decart's pay-as-you-go API costs $0.02 a second at 720p.
Questions about Odyssey-2
What is the difference between Odyssey-2 and Odyssey-2 Pro?
Odyssey-2 Pro is a larger model that Odyssey says improves on Odyssey-2 in physics, motion, behaviour and image quality, and it streams 720p at 22 frames a second. It was the first model in Odyssey's API.
Who is Odyssey-2 for?
Odyssey-2 is best for anyone curious to see live, steerable AI video in a browser, and for teams sizing up Odyssey before asking for access to its newer models.
Is Odyssey-2 free?
Yes, to try. Odyssey's web demo runs without sign-in or payment on a timed play allowance, and an email sign-up adds 20% more play time. There is no paid Odyssey-2 plan; Odyssey's paid API serves its newer models.
What are the best Odyssey-2 alternatives?
The closest alternatives on Recaply are MiniMax H3 Max, World Labs Marble and Lucy 2.5.
Where can I try Odyssey-2?
On its official website, odyssey.ml.
Does Odyssey-2 have an API?
No. Odyssey's API launched with Odyssey-2 Pro, the larger model that replaced Odyssey-2, and Odyssey-2 Max is now rolling out to existing API customers. New developers request access through a form, and Odyssey lists no public prices.
How is Odyssey-2 different from a normal AI video generator?
A typical video generator plans the whole clip at once, so you wait and cannot change it midway. Odyssey-2 predicts each frame from the ones before, so it starts streaming at once and reacts to new prompts while the video plays.
Our verdict
Odyssey-2 is worth a few free minutes as a glimpse of live, steerable AI video, but it is not something to build on.
It reacts to typed prompts within moments at 20 frames a second, yet Odyssey has replaced it with Odyssey-2 Pro and Max, and it has no API or prices of its own.
- Skip it for
- Anyone who needs an API, published prices, or a world they can walk through and keep.
- Check first
- If you want Odyssey's models in a product, ask Odyssey which model and price your API access would include.
