Nace.AI Launches Drex, a <6B Model Built Only to Decide, Topping Its Decision Index
rohanpaul_ai · x · 2026-09-26
Nace.AI announced Drex is generally available — a <6B parameter model specialized for decisions: facts in, a probability for every option out, in one pass with no text to parse.
It ranks #1 among 50 entries on their Decision Index 0.2 (40 tests of deciding rather than writing — contracts, causes, tool calls, routing, judgment — all chance-corrected), scoring 51.73 vs 51.67 for runner-up Jev 1.13.0. Every other top-ten model with a published size is 12B–36B.
Demo scenarios include StarCraft II orders, supply-chain checkpoints, Doom deathmatch decisions per tick, Lemmings skill assignment, and fleet combat commands. On conventional benchmarks Drex hits 85.1% GSM8K and 86.0% BANKING77, but trails on MuSR and ANLI.
