Holo4 is a new series of agentic models from H Company, available in 27B dense and 35B-A3B Mixture of Experts sizes. These models interact with software through any interface—GUIs, code, MCP, or APIs—and run on desktops, web, Android, and sandboxes using the same model.

  • Holo4 scores 61.7% on OSWorld 2.0 (27B) and 30.9% (35B-A3B), trailing only Opus 5.5 at a much lower cost.
  • It significantly outperforms its Qwen base model on professional software tasks like 3D modeling and game design.
  • The models were trained via supervised and reinforcement learning using the Agentic Task Factory, which generated ~10,000 tasks.
  • An updated Holotron4 Nano is also released, adapting the Nemotron 3 Nano Omni for agentic workflows.

Holo4 allows users to handle complex business workflows that require combining different interaction methods without switching models.
