Release of open-source agentic models Holo4 for GUI, code, and API automation
The new family of open-source agentic models Holo4 (27B dense, 35B-A3B MoE) handles GUI control, writing and running code, MCP, and API all in one model. On OSWorld 2.0, Holo4-27B achieves 61.7% compared to 81.8% for the Opus 5.5 model, but at significantly lower cost.
Companies building GUI, code, and API automation can deploy an open-source model with significantly lower per-task costs than closed frontier models, at the cost of lower accuracy on long agentic tasks.
