Holo4: powering generalist computer-use agents
huggingface ·
Hcompany has introduced Holo4, a new series of agentic models designed to power generalist computer-use agents across diverse interfaces. The lineup includes two primary sizes: a 27B dense model and a 35B-A3B Mixture of Experts variant, alongside an updated Holotron4 Nano model. Unlike specialized agents, Holo4 can interact with software through GUIs, code execution, MCP protocols, and APIs, allowing it to adapt to various platforms such as desktops, web browsers, and Android devices. The models were trained using supervised and reinforcement learning on tasks generated by Hcompany's Agentic Task Factory, which creates interactive environments from documentation. Benchmarks indicate that Holo4 competes with frontier closed models like Opus 5.5 on OSWorld 2.0 while utilizing significantly fewer parameters and incurring lower costs. Demonstrations highlight its proficiency in complex professional workflows, including detailed 3D modeling in FreeCAD and game development in Godot. All weights are available for open-source use on Hugging Face in multiple precision formats, and the models can be accessed via the H Models API.
