H Company Releases Holo4: Open-Weight Computer-Use Models That Click, Code and Call Tools Across Desktop, Web, Android and APIs

H Company released Holo4, a family of open-weight computer-use models designed to work as AI agents that can click on screens, write code, and call tools across different platforms including desktop, web, Android, and APIs. The models come in two sizes with different licensing options: a smaller version available under a non-commercial license and a larger version available under an Apache 2.0 license for commercial self-hosting. Holo4 addresses a gap where existing AI agents either fail without visual screens or get stuck when applications lack APIs, by using a single model that works consistently across all these different interfaces. On benchmark tests, Holo4 27B achieves 85.2% performance on OSWorld at a cost of $0.08 per task, significantly cheaper than competing models like Claude Opus 5.5, though those models still score higher on longer, more complex workflows.
