Holo4 27B launch Verified

Holo4 combines screens, code and APIs in one agent model family

H Company's September 28 release includes 27B and 35B-A3B models, hosted access and downloadable weights. The 27B checkpoint is licensed for noncommercial use.

Why now The release provides public checkpoints and benchmark trajectories for inspecting agents that switch between graphical interfaces and tools. 27B and 35B-A3B variants

What happened

H Company released Holo4 on September 28 with a 27B dense model and a 35B-A3B mixture-of-experts model. The family is trained to use graphical interfaces, run code and call MCP or API tools within the same workflow. The announcement lists hosted access through H Models API and downloadable checkpoints.

Evidence beyond a demo

H Company publishes benchmark trajectories and reports a 61.7% OSWorld 2.0 score for Holo4 27B. Its own notes say model releases, harnesses and task subsets differ across parts of the comparison. These scores should be treated as release-team results, not a controlled ranking independently reproduced by AITrending.

The license is a deployment detail

The Holo4 27B model card declares CC BY-NC 4.0. Public weights do not mean unrestricted commercial use. Hosted service terms also need separate review.

For developers, the practical test is whether one model can recover when a screen changes, a tool fails or an API cannot complete a step. Inspecting the published trajectories is a useful starting point before assigning it access to real business applications.
