Paris-founded **H Company** released its new **Holo4** agent models on September 28, 2026\. According to the company's announcement, the models can use a computer the way a person does, through the screen, write and run their own code, and call the tools of other software. The weights are open for anyone to download on Hugging Face.

## What Holo4 is

Holo4 is a series of agent models built to carry out a task on a computer from start to finish. The model looks at a screenshot and decides where to click and what to type; when needed, it writes and runs code or calls tools through MCP and APIs. According to the company, the same model works the same way on the desktop, on the web, on Android phones and against business software APIs. The models are used with an agent harness the company shares on GitHub, which sends screenshots to the model and carries out its decisions.

## Which models were released

The series has two models. Holo4 27B is built on Alibaba's Qwen3.8-27B. Holo4 35B-A3B is a mixture-of-experts model built on Qwen3.6-35B-A3B, with 3 billion parameters active at each step. Both accept inputs of up to 256,000 tokens. The weights come in several precisions; the 4-bit GGUF versions are about 17 GB for the 27B and about 21 GB for the 35B-A3B. The company also released Holotron4 Nano, built on NVIDIA's Nemotron 3 Nano Omni, and a dataset of 7,366 recorded task runs from its evaluations.

## Who can use it

The licenses differ by model. Holo4 35B-A3B is released under Apache 2.0 and is open to commercial use. Holo4 27B is under CC BY-NC 4.0, so it can be used only for non-commercial work; the company offers this model commercially through its own paid API. Holotron4 Nano is covered by the NVIDIA Open Model Agreement. Current prices are on the company's site.

According to the company, Holo4 27B scores ahead of the Qwen model it is built on in computer-use tests, and trails the strongest closed models on long workflows. The company notes that it measured the results in its own test setup and that part of the AutomationBench tasks come from the split it collected training data from. Neither the announcement nor the model cards cover supported languages or the risks of the model acting on a real computer; running such agents in a separate test environment first is a sensible step. For a fuller picture, it is worth following evaluations from independent researchers as well.
