Odyssey ML Raises $310 Million to Build AI World Models, Names AWS as Preferred Cloud Provider

Odyssey ML, a startup developing AI systems that simulate the physical world, has raised $310 million at a $1.45 billion valuation in a round that cements Amazon as a central partner in its infrastructure strategy. The deal, first reported by the Financial Times on Tuesday, makes AWS Odyssey’s preferred cloud provider and grants access to Amazon’s Trainium chips — a move that bolsters Amazon’s push to compete with Nvidia in the AI chip market.irishtimes

A Coalition of Chip Rivals

The round was led by Natural Capital, with participation from Amazon, AMD Ventures, GV (formerly Google Ventures), the CIA-affiliated fund IQT, and individual investors including Google’s chief scientist Jeff Dean and Elad Gil. Notably, Nvidia’s venture arm NVentures also participated — just four months after it backed Odyssey in a February investment alongside Samsung Next.pulse2

The unusual arrangement of having rival chipmakers Amazon, AMD, and Nvidia all on the cap table reflects Odyssey’s compute-intensive needs. The company’s tools currently run on Nvidia’s H200 and B200 chips, with usage costs of $2 to $4 per hour per person, according to CEO Oliver Cameron. As part of this deal, Odyssey will also deploy Amazon’s latest-generation Trainium chips for training workloads.irishtimes

Betting on the ‘Second Wave of AI’

Odyssey, founded by former self-driving engineers Cameron and Jeff Hawke, is building what it calls general-purpose world models — AI systems trained on physics and spatial relationships rather than language alone. In a demonstration, Cameron showed the model recreating a multiplayer version of the 1997 Nintendo game GoldenEye based solely on “pixels, actions and sounds,” rather than the game’s underlying code.irishtimes

“We have taken a human brain-like construct and only taught it language,” said Jay Zaveri, a partner at Natural Capital. He described world models as part of a “second wave of AI” poised to reshape industries from robotics to gaming.irishtimes

Amazon’s Chip Ambitions

For Amazon, the investment extends a broader strategy to build an ecosystem around its custom silicon. CEO Andy Jassy said earlier this year that the company had $225 billion in outstanding Trainium contracts, with Trainium3 — which began shipping in early 2026 — offering 30 to 40 percent better price-performance than its predecessor.aboutamazon

Ron Diamant, an AWS vice-president, said Odyssey’s feedback would help refine Trainium’s development. “My goal is to be able to tell my son that I built the best AI accelerator in the world,” he said.irishtimes

The 55-person company, spread across London, Zurich, and Palo Alto, plans to use the capital to scale training infrastructure as it races to deliver what GV partner Luna Schmid called a potential “GPT-3 moment” for world models.irishtimes
