Description

Holo3.1 represents H Company’s advanced suite of swift and localized computer-use agents designed for seamless operation across web, desktop, and mobile platforms, while ensuring better integration within various agent frameworks and deployment targets. Drawing from the Qwen family, Holo3.1 significantly enhances reliability in the diverse environments where these agents are utilized, tackling the distribution changes that arise on mobile devices, alternative agent frameworks, and varied execution environments. The latest version broadens Holo3’s functionality, going beyond mere browser and desktop control, with notable advancements in mobile automation; for instance, the performance in AndroidWorld has surged from 67% to 79.3% for the 35B-A3B model, while the smaller 4B and 9B variants have also shown improvements from 58% to 71%. In addition, Holo3.1 brings forth native support for function-calling protocols alongside structured JSON outputs, which aids teams in integrating the model into third-party agent ecosystems, achieving almost identical performance between function-calling and native execution. This release marks a significant step in enhancing the versatility and effectiveness of computer-use agents across multiple platforms.

Description

Holo4 is H Company's series of generalist computer-use and agentic AI models built to perform multi-step work across software interfaces. It is available as Holo4 27B, a dense 27-billion-parameter model, and Holo4 35B-A3B, a Mixture-of-Experts model containing 35 billion total parameters with 3 billion active. Holo4 can interact with applications by clicking and typing through graphical interfaces, writing and executing code, or calling MCP and API tools. The same model can operate across desktops, websites, Android devices, code sandboxes, and business APIs without requiring developers to select a separate specialized model for each environment. H Company trained Holo4 using 127 billion supervised fine-tuning tokens, with approximately three-quarters consisting of successful agentic trajectories spanning desktop, web, MCP/API, and mobile tasks. Reinforcement learning then trained separate experts for desktop and web interaction and for terminal, MCP, and API work before merging them into a single model. Holo4 27B scored 85.2% on OSWorld, 61.7% on OSWorld 2.0, 45.4% on AutomationBench, and 85.1% on AndroidWorld in the evaluations reported by H Company. The models support a 256K context window, with the 27B model positioned for greater accuracy on long multi-step tasks and the 35B-A3B version positioned as a faster and less expensive alternative. Holo4 is available through a hosted API and downloadable model weights, enabling developers and enterprises to build agents that perform workflows spanning multiple applications and interaction methods.
