Microsoft Research introduces Echoverse, a set of twelve synthetic training worlds for computer-use agents, designed with high fidelity and depth. Training a 9B model on all twelve worlds nearly doubled its base score from 36.5% to 67.1%, coming within fourteen points of GPT-5.4. The project emphasizes co-evolution of the model, world, and verifier, and releases four worlds with code, data, and graders on GitHub and Hugging Face.
