Hesamation · x · 2026-09-25
NaceAI released Drex, a decision-focused small model under 6B parameters: facts in, a probability for every option out in one pass, no text parsing. It scores 51.73 on Decision Index 0.2, narrowly beating Jev 1.13.0 (51.67) to rank first among 50 entries, while other top-ten models with published sizes range from 12B to 36B.
Drex is a diffusion model trained with RL from adjusted feedback, with 136ms response time (1.5x faster than Jev), aimed at agent routing, tool selection, reranking and guardrails. Demos show it making real-time decisions in StarCraft II, Doom, Lemmings and more. The first 10,000 builders get 250M free tokens.
