What is Odyssey-2 Max?
Odyssey-2 Max is the third and largest model in Odyssey's Odyssey-2 family. Like Odyssey-2 Pro, it predicts each frame from earlier frames and your actions, so it runs in real time and can be steered while it plays. It has about three times Pro's parameters and ten times its training compute, and Odyssey's own tests show the gain mostly in physics.
It is not generally available. Odyssey offers it in private beta to partners in robotics, gaming, simulation, defense and interactive systems, and is rolling it out to existing API users; everyone else can request priority access.
How do you get access to Odyssey-2 Max?
Only by invitation for now: it is in private beta for partners and is rolling out to existing Odyssey API users.
- Partners
- Odyssey offers the beta to teams in robotics, gaming, simulation, defense and interactive systems.
- Existing API users
- The developer portal says Max is being rolled out to current accounts; sign in with your account email.
- New users
- The portal links to Odyssey's contact form, asking for your name, email, organisation and a message, to request priority access.
- Price
- None published; Odyssey's API fees are set in a contract.
What changed from Odyssey-2 Pro?
Mostly scale and physics: the same real-time design, about three times bigger, with clearly higher physics scores.
- Size
- About 3x the parameters and 10x the training compute of Odyssey-2 Pro.
- Physics
- 58.52 against 49.67 on VBench 2, and 93.02 against 91.67 on PAI-Bench physics.
- Image quality
- 71.17 against 67.46 on the image quality measure in Odyssey's table.
- Access
- Pro launched as an open API; Max is private beta and a gradual rollout.
Who is Odyssey-2 Max best for?
Odyssey-2 Max is best for partner teams in robotics, simulation, gaming and defense, and for existing Odyssey API customers as it rolls out to them.
Robotics and simulation teams
Odyssey aims the private beta at partners who need physically plausible rollouts, such as robotics, simulation and defense work.
Game and interactive studios
Gaming and interactive systems are among the partner fields Odyssey names for the beta.
Existing Odyssey API customers
Odyssey is rolling it out to accounts already on its API, so current Odyssey-2 Pro users are first in line.
What's included with Odyssey-2 Max?
Real-time rollouts you can steer, open-ended action input, long context, stable long runs and fast few-step generation.
- Real-time, steerable rollouts
- It predicts each frame from earlier frames and actions, so the video reacts to input as it plays instead of being rendered in advance.
- Open-ended action input
- It conditions on embeddings of actions rather than a fixed control set, which Odyssey says lets it take many kinds of input.
- Long context
- A custom cache lets it run on sequences up to 20x longer than prior work, for dynamics that only show up over time.
- Long-horizon stability
- A final training stage targets steady output over long rollouts; Odyssey's table lists 120+ seconds of generation.
- Few-step generation
- It is distilled to make each frame in a small number of denoising steps, which keeps it real time.
How much does Odyssey-2 Max cost?
Odyssey-2 Max has no public price: it is in private beta by invitation, and Odyssey's API fees are set in a contract billed monthly in advance.
- New users request priority access through Odyssey's contact form
- API fees are set in a contract and billed monthly
- No public price list
Odyssey publishes no prices for Odyssey-2 Max and has no pricing page. Under its API terms, fees are set in each customer's order, billed monthly in advance and non-refundable. Full pricing on developer.odyssey.ml. We checked these prices on .

Odyssey-2 Max pros and cons
It posts Odyssey's highest published physics scores, but it is invitation-only, unpriced in public, and not ahead on every measure.
Pros
- Odyssey's highest published physics scores: 58.52 on VBench 2's physics measure against 49.67 for Odyssey-2 Pro, and 93.02 against 91.67 on PAI-Bench physics.
- Keeps the real-time, steerable format of Odyssey-2 Pro while being about three times larger.
- Runs longer than the NVIDIA Cosmos models in Odyssey's table, 120+ seconds against 30, and beats them on VBench 2 physics.
Cons
- Not generally available: it is in private beta for partners and rolling out to existing API users, and new users must ask for access.
- No public prices; Odyssey's API fees are set by contract and billed monthly in advance.
- Not top on every measure in Odyssey's own table: Cosmos-Predict2.5-14B scores higher on PAI-Bench physics, 93.50 against 93.02, and Odyssey-2 Pro scores higher on subject and background consistency.
What are the best Odyssey-2 Max alternatives?
MiniMax H3 Max for live video you can use now, World Labs Marble for 3D worlds you can keep, and Lyra 2.0 for open weights you can run yourself.
MiniMax H3 MaxFreeChoose it when you need live, prompt-steered video you can pay for now; its Director endpoint on fal lists $0.08 a second, with sessions of up to 15 minutes.
World Labs MarbleFreeChoose it when you want 3D worlds you can walk around, keep and export today; its free plan gives 7,000 credits a month, up to 4 worlds, and mesh export starts at $20 a month.

Questions about Odyssey-2 Max
What is Odyssey-2 Max?
Odyssey-2 Max is Odyssey's largest Odyssey-2 world model, streaming AI video that reacts to your input in real time; it is in private beta for partners and rolling out to existing API users.
Who is Odyssey-2 Max for?
Odyssey-2 Max is best for partner teams in robotics, simulation, gaming and defense, and for existing Odyssey API customers as it rolls out to them.
Is Odyssey-2 Max free?
There is no public free access. Odyssey-2 Max is in private beta for partners and rolling out to existing Odyssey API users, Odyssey publishes no prices, and its API fees are set in a contract billed monthly in advance.
What are the best Odyssey-2 Max alternatives?
The closest alternatives on Recaply are MiniMax H3 Max, World Labs Marble and Lyra 2.0.
Where can I try Odyssey-2 Max?
Only through Odyssey. Existing API users sign in at the developer portal as the rollout reaches them; others request priority access through Odyssey's contact form. Odyssey's announcement links to no public demo.
Is Odyssey-2 Max the same as Odyssey-3?
No. Odyssey-2 Max is the largest model in the Odyssey-2 family, built for real-time, steerable world simulation. Odyssey-3 is a separate foundation world model that Odyssey uses as a base for robot, car, drone and game-playing policies, and it has not been released.
How was Odyssey-2 Max trained?
On several hundred NVIDIA B200 GPUs, according to Odyssey, in three stages: general video pretraining, then training to respond to actions and tasks, then training for stable output over long rollouts.
Our verdict
Odyssey-2 Max is the most capable model Odyssey offers today, but only to partners and existing API customers.
Odyssey's own tests put its physics well ahead of Odyssey-2 Pro while keeping real-time steering, yet there is no public price, no demo and no open sign-up.
