Decart raises $300M for its AI optimization software, world models

Artificial intelligence developer Decart.ai Inc. today announced that it has raised $300 million in funding at a nearly $4 billion valuation.

Radical Ventures led the round with participation from Nvidia Corp., Adobe Ventures, Toyota Ventures and other institutional backers. They were joined by several prominent angel investors including OpenAI Group PBC co-founder Andrej Karpathy.

Decart announced the raise alongside an update to DOS, one of its three software products. The platform helps AI developers speed up training and inference workloads. Decart says that it’s generating “significant revenue” from DOS licensing agreements with cloud providers and AI labs.

Typically, developers have to optimize a neural network for every single chip on which they plan to run it. The process can take months. Decart says that DOS compresses the workflow into a few weeks, which reduces the cost of optimizing a model for multiple chips. That cost reduction, in turn, makes it easier for companies to move their AI workloads across chips when requirements change.
