Odyssey ML raises $310 million Series B to develop general world models that simulate physical environments

AI Judge changed title after evaluation, original title: "Odyssey ML raises $310 million to develop general world models using real-time video generation"

Story Overview

Odyssey ML just closed a $310 million Series B that values the two-year-old lab at $1.45 billion post-money. The round brings Amazon in as lead alongside GV and AMD, giving the startup fresh capital to train causal, multimodal systems that simulate physics and object behavior through live video rather than text alone.

When @jeffrey_hawke and I started @odysseyml in 2023, we believed general world models would become a new class of foundation model.

Three years later, it now feels true. And today, we're announcing a $310M Series B.

AI can now understand and simulate the world!

Odyssey@odysseyml

We’ve raised a $310M Series B to accelerate world models!

We believe AI that can understand and simulate the world will be one of the most important technologies of our time.

We're excited to partner with Natural Capital, Amazon, GV, AMD, IQT, and others to bring this to life.

Investor Interest

Big names see leverage in video-first simulation

Amazon’s involvement includes a preference for its cloud and silicon, while GV and AMD add further hardware and research weight. The move signals that investors view real-time world models as a distinct foundation-model category worth scaling now.

Open Question

Early traction sets stage for broader experiments

Odyssey already has roughly 55 people and prior seed and Series A rounds totaling about $27 million. How the new money translates into released models or third-party applications remains to be seen.

Sentiment

Many users congratulated Odyssey ML on its $310M Series B and voiced excitement about progress in world models, while a few sarcastically questioned the technology's novelty compared to game engines.

He was the first to explain real time world models to us. Such an interesting dude.

@olivercameron @jeffrey_hawke @odysseyml Believing in world models back in 2023 must have taken serious conviction.

Congrats on the series B.

@olivercameron @jeffrey_hawke @odysseyml I can’t imagine how it must feel to finally have the resources to build something you’ve been planning and dreaming about for so long.
