# Nebius Acquires Eigen AI for $643M to Scale Frontier Inference

> Nebius, the cloud and AI infrastructure company, is buying Eigen AI in a deal worth about 643 million dollars, structured as roughly 98 million in cash plus 3.8 million Nebius shares. Eigen specializes in inference and model optimization, the unglamorous but decisive work of making models run faster and cheaper once they are actually serving users. The team behind Eigen comes out of MIT's HAN Lab, a group known for research on compressing and accelerating neural networks, and they will set up an engineering hub in the San Francisco Bay Area. Their technology folds into the Nebius Token Factory, the company's managed platform for inference and post-training optimization, and the acquisition marks Nebius pushing further into the US market after clearing regulatory approval. The pattern worth noticing is where the money is flowing. As raw model quality converges, the competitive edge increasingly comes from serving those models efficiently at production scale. Buying a specialist inference team is a bet that the next phase of the AI business is won on cost per token, not just on benchmark scores.
