Stable model
Hydrogen-2
Proprietary. Hydrogen models and the Hydrogen name are UnikAI property. This page covers our current stable release. It is not permission to redistribute weights or training details.
Hydrogen-2 is our current stable model. We pair it with MAUL-2: math routes to SymPy, code runs in a sandbox, everything else gets the right specialist. You get one answer.

- GSM8K: 95.90%
- HumanEval: 97.56%
These are the same tests we run before calling a build stable. Real results depend on your prompt and data.
How it works with MAUL-2
Hydrogen generates text. MAUL-2 decides when to use tools and which specialist to involve. Hard math never goes to the LLM; it goes to a calculator. Code runs in a sandbox. That keeps the LLM doing what language models are good at, and lets deterministic tools handle the rest.
