Holo4 is a new series of agentic models designed to interact with software through any available interface: GUIs, code, MCP, and APIs. It comes in two sizes, a 27B dense model and a 35B-A3B Mixture of Experts model, both available on the H Models API. The models were trained through supervised and reinforcement learning on environments and tasks generated by the Agentic Task Factory, which produces verifiable tasks from documentation alone. On the OSWorld 2.0 benchmark, Holo4 27B scores 61.7% against 81.8% for Opus 5.5, achieving competitive performance at a fraction of the cost. The company also released Holotron4 Nano, an updated version of Holotron 3 built on the Nemotron 3 Nano Omni model using the same post-training stack.
