MarkTechPost 4 days ago 31 ● 8 sources
Nace.AI open-sourced Drex 1.5, a 9B decision model that scores a provided set of options from a state and typed questions instead of generating text. It reports 58.08 on the Decision Index 0.3.1 public leaderboard. Developers can now run it via Hugging Face weights and options like OpenRouter hosting, while it replaces prior “Jev-style” clients with the same systemone API but different model behavior.
