H Company releases Holo4 models for agents that operate software
Paris-based H Company introduced Holo4, agentic models in 27B dense and 35B-A3B mixture-of-experts sizes, plus an updated Holotron4 Nano. The models work through GUIs, code, MCP and APIs.
H Company announced Holo4 on September 28, a series of agentic models built to interact with software through any available interface, including graphical interfaces, code, MCP and APIs.
Holo4 comes in a 27B dense version and a 35B-A3B mixture-of-experts version, both on the H Models API, with model pages on Hugging Face. The company also released Holotron4 Nano. H says the models were trained with supervised and reinforcement learning on many environments, including tasks from its Agentic Task Factory, and were built for real business workflows.
