H Company has opened its fully managed computer-use agent API to the public in open beta. The service allows users to deploy browser agents that can see screens, click, type, and navigate within isolated cloud sessions without needing to host models or manage virtual machines.
The underlying model, Holo3, is built specifically for computer use tasks and currently ranks #1 on OSWorld-verified benchmarks. It was post-trained on thousands of real-world environments generated by the company's environment factory and utilizes a custom harness for reliability. The initial release includes browser environment support along with Python and TypeScript SDKs.
The company is seeking feedback, particularly from users who have conducted their own evaluations on OSWorld-verified.
