THX-02 is here. Our new open-source Thinking Decision Model.
Today we open-sourced THX-02, our second-generation 4.5B-parameter decision model, developed at HAL-X AI and launched in collaboration with ModelScope (Alibaba) with FREE API, check below for documentation.
Unlike traditional decision models, THX-02 introduces adaptive reasoning. It thinks when a decision is complex or uncertain, and answers directly when reasoning isn't needed, typically in under 100 ms.
Decision Index 0.3 (37 decision tasks):
- 65.06 with reasoning
- 63.83 without reasoning
- Outperforms TypeSafe Jev and decision models up to 6× its size
THX-02 supports calibrated probabilities, multilingual decision-making, and native reasoning, with special attention to Azerbaijani and other underrepresented languages.
Fully open-source under Apache 2.0:
- 4.5B parameters
- Adaptive thinking and non-thinking modes
- Weights, reasoning adapter, runtime, and server available
- Self-hostable on your own infrastructure
- Python:
