Holo4 27B timeline
What it does
H Company introduced Holo4 on September 28 as an agent family that can click through graphical interfaces, run code and call MCP or API tools. The 27B dense checkpoint is based on Qwen3.8 27B. The family also includes a 35B-A3B mixture-of-experts model and Holotron4 Nano.
Evidence available
H Company reports a 61.7% OSWorld 2.0 result for the 27B model and publishes benchmark trajectories for inspection. Its cost comparisons combine different task releases, harnesses and task subsets, so the plotted results should not be read as a controlled, universal ranking.
The public Hub API returned 105 downloads and 47 likes when checked on September 30. These are repository counters, not measures of successful production use.
Deployment and license
The model card declares cc-by-nc-4.0. Downloadable weights therefore do not imply unrestricted commercial use. Review the license and any separate hosted-service terms before deciding how to deploy it.
Test the model against the actual applications it will control. Task completion, recovery after failed actions and permission handling matter more than whether it can produce a convincing demonstration.
