Holo4: powering generalist computer-use agents

Holo4 is a new series of agentic models, available in two sizes, that can interact with software through multiple interfaces including graphical user interfaces, code, APIs, and other tools. The models are designed to handle real business workflows and were trained using supervised and reinforcement learning on various environments and tasks. On academic benchmarks for desktop control and API use, Holo4 achieves competitive performance with the strongest closed models while using significantly fewer parameters and costing substantially less per task. The models can work across different platforms including desktops, web applications, Android devices, code sandboxes, and business APIs without requiring different versions for each environment.
