What is Odyssey-2 Pro?
Odyssey-2 Pro is a world model from Odyssey, an AI lab. Instead of rendering a whole clip up front, it predicts each frame from the ones before, so video starts streaming at once and changes course when you type a new instruction. Odyssey says it is a much larger model than Odyssey-2, with better physics, motion and behaviour, streaming 720p at 22 frames a second.
It was the first model in Odyssey's API. Odyssey has since added Odyssey-2 Max and announced Odyssey-3, and its developer portal now asks new users to request access, while existing accounts can still sign in.
How do you get access to Odyssey-2 Pro?
Through Odyssey's API, which new developers must now ask to join; there is no public sign-up or price list.
- Existing API users
- Sign in at Odyssey's developer portal with your account email and create API keys there.
- New developers
- The portal sends you to Odyssey's contact form, asking for your name, email, organisation and a message, to request priority access.
- Contract
- Fees are set in an order under Odyssey's API terms, billed monthly in advance on a rolling monthly term.
What changed from Odyssey-2?
A bigger model with sharper, steadier output, and the first one you could build with through an API.
- Size
- Odyssey calls it a significantly larger model, trained on more video and interaction data.
- Picture
- It streams 720p at 22 frames a second.
- Physics
- It edges Odyssey-2 on Odyssey's physics tests: 49.67 against 48.58 on VBench 2.
- API
- Odyssey-2 was a web demo; Odyssey-2 Pro launched Odyssey's developer API and SDKs.
Who is Odyssey-2 Pro best for?
Odyssey-2 Pro is best for developers who already have Odyssey API access and want live, prompt-steered video in an app, a kiosk or a batch pipeline.
Developers already on Odyssey's API
It is the model Odyssey's docs and SDKs are written around, so existing accounts can build with it straight away.
Kiosks, installations and live demos
One running stream can be broadcast to many screens, and Odyssey's docs show how to chain streams so the picture never stops.
Scripted scene generation
Batch simulations take a prompt, timed actions and a target length and return a finished video, with up to 10 jobs queued at once.
What's included with Odyssey-2 Pro?
Live text steering, image starts, broadcasts to many viewers, batch simulations, recordings of each stream, and JavaScript and Python SDKs.
- Live text steering
- Send a new prompt while the stream plays and the video changes course without restarting.
- Image starts
- Begin from a picture of up to 25MB in common formats including JPEG, PNG, WebP and HEIC; it is resized to 1280x704 or 704x1280.
- Broadcast
- Many viewers can watch one running stream, and spectators do not count toward your concurrent stream limit.
- Batch simulations
- Scripted jobs run in the background and return a recording, useful when nobody needs to watch live.
- Recordings
- After a stream ends you can fetch its full video, an events log, a thumbnail and a preview by its stream ID.
- JavaScript and Python SDKs
- Official clients, including a React hook, plus short-lived browser credentials so your API key stays on the server.
How does Odyssey-2 Pro work?
Get an API key
Sign in at Odyssey's developer portal, or request access first if you do not have an account.
Connect
Opening a connection reserves a GPU-backed streamer, so streams start quickly.
Start a stream
Pass a text prompt, and optionally an image, and attach the returned video to your page.
Steer, then close
Send new prompts as it plays, start a fresh stream every 150 seconds, and disconnect when you are done.
How much does Odyssey-2 Pro cost?
Odyssey-2 Pro has no public price: Odyssey sells API access by request, with fees set in a contract and billed monthly in advance.
- New developers request access through a form
- Month-to-month term, billed monthly in advance, renews automatically
- Overage fees can apply above your usage limits
Odyssey publishes no prices and has no pricing page. Its docs mention a Free tier account with up to 5 concurrent streams but say nothing else about it. Under the API terms, fees are set in each customer's order and are non-refundable. Full pricing on developer.odyssey.ml. We checked these prices on .

Odyssey-2 Pro pros and cons
It streams at once and gives developers several ways to build, but access is by request, streams stop after 150 seconds, and physics still slips.
Pros
- Streams at once and reacts mid-stream: a new frame every 50 milliseconds, where Odyssey says typical video models need a minute or two for five seconds of footage.
- Three ways to build with it: live interactive streams, one stream broadcast to many viewers, and batch simulations, with JavaScript and Python SDKs.
- Better physics than Odyssey-2 on Odyssey's own tests: 49.67 against 48.58 on VBench 2 and 91.67 against 89.50 on PAI-Bench physics.
Cons
- No self-serve start: the developer portal now asks new users to request access, and Odyssey publishes no prices.
- Short streams: each one stops after 150 seconds and a connection after an hour, so long sessions need restart code that leaves a gap of a second or two.
- Physics still slips: Hacker News readers spotted a lion's tail jumping about and attaching to a girl, and a diver's bubble turning into a jellyfish, in Odyssey's own sample clips.
- Your prompts and outputs can be used to train Odyssey's models under its API terms, and you may not train your own models on the output without consent.
What are the best Odyssey-2 Pro alternatives?
MiniMax H3 Max for live video you can pay for now, Lucy 2.5 for real-time edits of camera video, and Odyssey-2 for a free look in the browser.
MiniMax H3 MaxFreeChoose it when you want prompt-steered live video you can pay for today; its Director endpoint on fal lists $0.08 a second, with sessions of up to 15 minutes.
Lucy 2.5FreemiumChoose it when you want to edit or restyle live camera video rather than imagine a scene; Decart charges $0.02 a second at 720p, and new accounts get free credits.
Odyssey-2FreeChoose it when you only want to see Odyssey's live, steerable video for yourself; its web demo is free in a browser with no sign-in.
Questions about Odyssey-2 Pro
What is Odyssey-2 Pro?
Odyssey-2 Pro is Odyssey's real-time world model that streams 720p video you steer with text prompts, sold through an API that new developers must now ask to join.
Who is Odyssey-2 Pro for?
Odyssey-2 Pro is best for developers who already have Odyssey API access and want live, prompt-steered video in an app, a kiosk or a batch pipeline.
Is Odyssey-2 Pro free?
Not openly. Odyssey's docs mention a Free tier account with up to 5 concurrent streams, but new developers must request access first and Odyssey lists no prices. Paid use runs on a contract billed monthly in advance.
What are the best Odyssey-2 Pro alternatives?
The closest alternatives on Recaply are MiniMax H3 Max, Lucy 2.5 and Odyssey-2.
Where can I try Odyssey-2 Pro?
Odyssey's docs link their Odyssey-2 Pro prompt examples to its free web demo at experience.odyssey.ml, which runs in a browser with no sign-in, though the demo does not name its model. Building with Odyssey-2 Pro needs API access.
Odyssey-2 Pro vs Odyssey-2 Max: which should I use?
Max is about three times the size of Pro and scores higher on Odyssey's physics tests, 58.52 against 49.67 on VBench 2, but it is in private beta and only rolling out to existing API users. Pro is the model Odyssey's public docs describe.
How long can an Odyssey-2 Pro stream run?
Each interactive stream runs for up to 150 seconds. You can start the next one on the same connection, which stays open for up to an hour, and Odyssey's docs show how to overlap two sessions to hide the gap.
Does Odyssey train on my Odyssey-2 Pro prompts and videos?
It can. Under Odyssey's API terms you own your prompts and outputs, but you give Odyssey a licence to use them to develop, train and improve its models. You also may not train your own models on the output without Odyssey's consent.
Our verdict
Odyssey-2 Pro is worth asking for if you want live, steerable video inside a product, but you can no longer just sign up and start.
It streams 720p video that changes as you type and comes with broadcasts, batch jobs and SDKs, yet new users must request access, prices are set by contract, and Odyssey-2 Max is rolling out to existing accounts.
- Skip it for
- Anyone who needs published prices, self-serve sign-up or unbroken streams longer than 150 seconds.
- Check first
- Ask Odyssey which model your access includes, what the free tier allows, and how it uses your prompts and output.
