H Company has launched Holo4, a family of open-weight models built to serve as generalist computer-use agents. The models can interact with graphical interfaces by clicking and typing, generate code, and invoke external tools through MCP or API connections.
Holo4 ships in two configurations: a 27B dense model and a 35B-A3B mixture-of-experts architecture with 3B active parameters. The MoE variant aims to balance capability with inference efficiency by activating only a fraction of its total parameters per token.
Computer-use models represent a growing frontier in AI agent research, where systems must translate high-level instructions into concrete actions across diverse software environments. By supporting desktop, web, Android, and API surfaces, Holo4 targets broad interoperability rather than a single platform.
Releasing the weights openly could encourage community fine-tuning and evaluation, potentially accelerating progress in agentic tool use. The inclusion of MCP support also aligns Holo4 with emerging standards for connecting language models to external services and data sources.
