Holo4: powering generalist computer-use agents
Hugging Face
Holo4’s developers released a new series of agentic models that can use multiple software interfaces, from GUIs to code and APIs, on a single model per platform. Holo4 is offered in two sizes—27B dense and 35B-A3B Mixture of Experts—available on the H Models API. It updates Holotron 3 into Holotron4 Nano and shifts agent training and evaluation toward real business workflows with reported cost-performance on benchmarks like OSWorld 2.0.
