Holo Models API

The Holo Models API is H Company's developer-facing interface for accessing Holo3, a family of multimodal models built to interpret content and execute tasks across real-world digital environments. Developed by H Company, a Paris-founded AI company, the API is currently available for builders to start integrating via the H Company hub. The product sits at the core of H Company's broader stack, which also includes the HoloTab browser extension and an enterprise autonomous operations platform.

What It Is

The Holo Models API gives developers programmatic access to Holo3 models — multimodal AI models that H Company describes as designed to "interpret content and operate across real-world digital workflows." Unlike general-purpose language models, the Holo3 family is positioned specifically for computer-use and action-oriented tasks: navigating interfaces, understanding screen content, and completing multi-step digital operations. The API is the building block for developers who want to embed these capabilities into their own applications or agents.

The Holo3 Model Family

H Company's model lineup under the Holo brand includes:

• Holo 3 — the base multimodal model for computer-use and digital workflow interpretation, available via the API
• Holo 3.1 — released June 1, 2026, described by H Company as "the next generation of our computer-use model family"
• Holotron 3 Nano — introduced April 28, 2026, built by post-training NVIDIA's Nemotron 3 Nano Omni, targeting efficient deployment

The model family is multimodal, meaning it can process and act on visual and textual inputs from digital environments.

Where It Fits in the Stack

H Company positions the Holo Models API as one layer of a full-stack enterprise AI system. The broader platform combines models, advanced agents, scalable execution, and continuous learning. The API enables developers to access the model layer directly, while the enterprise offering wraps these models into a managed platform for production deployments. HoloTab, the company's Chrome extension, is a consumer-facing product that also runs on the same underlying model capabilities.

Developer Access and Setup

Developers can access the Holo Models API through the H Company hub at hub.hcompany.ai, where a quickstart guide is available. The API is described as currently available for builders to start integrating. No specific SDK or language support details are surfaced in the available sources beyond the hub quickstart path.

Update: Holo 3.1 Release

H Company released Holo 3.1 on June 1, 2026, marking the latest iteration of the computer-use model family. Prior to that, Holotron 3 Nano launched on April 28, 2026. These releases signal active model development and a cadence of incremental capability improvements within the Holo model family. The product direction points toward increasingly capable and efficient computer-use models accessible via the API.
