H Company announces Holo4 and says its models compete with frontier systems
H Company announced the Holo4 series of models for computer-use agents. The Holo4-27B dense model and Holo4-35B-A3B mixture-of-experts model are available through the H Models API, along with an update called Holotron4 Nano. The company says the models can click and type in graphical interfaces, write and run code, and call MCP tools or APIs, operating on desktops, the web, Android, code environments and business APIs.
H Company says Holo4 competes with frontier models on computer-use and API tasks, with fewer parameters and a much lower cost per task. On the OSWorld 2.0 benchmark, the company reports that Holo4 27B scored 61.7%, compared with 81.8% for Opus 5.5, while Holo4 35B-A3B scored 30.9%. The models were trained with supervised and reinforcement learning across varied environments and tasks, including data generated by the Agentic Task Factory.
Why it matters · editorial interpretation
H Company’s API availability could make it easier to integrate agents that operate interfaces and call tools into applications. However, the company’s own comparison is uneven on OSWorld 2.0: Holo4-27B scored below Opus 5.5, while Holo4-35B-A3B scored lower still.
