Hydrogen-1
Proprietary. Hydrogen-1 is UnikAI confidential. This page exists so people stop confusing old experiments with Hydrogen-2, not to share weights or implementation details.
Hydrogen-1 was a series of internal runs: different data mixes, tool settings, and MAUL versions. Nothing here is something you should build on. We keep it for history.
What we saw on GSM8K
Our best Hydrogen-1 setup hit 95.75% on GSM8K. An earlier run landed at 95.68%. Hydrogen-2 is the line we support and publish numbers for.
How it led to Hydrogen-2
What we learned from those runs went into Hydrogen-2 and MAUL-2: what to route to tools, how to define a stable release, where the model needed help. You don't need Hydrogen-1 to use what we ship today.
