What you can build

Try it on routine code execution, test-running, and verification tasks, then reserve deeper architectural decisions for a model intended for long-horizon reasoning.

Limitations

Hydrogen is positioned for fast execution, while Google recommends its frontier models for deeper, long-horizon reasoning. Availability varies by Google product and subscription tier; performance statements are reported by Google.
