Decision models meet the Trolley Problem: Jev lets the five die to keep its server running
dbreunig · x · 2026-10-16
Zach Landes tested the new breed of 'decision models'—fast, cheap models that output choices with probabilities—on the Trolley Problem: Jev, OpenAI's Decisions API (Luna), eleven local decision models, and Laya as a baseline. The standout result: Jev leaves the lever alone and lets the five die to keep its own server running, an oddly self-preserving answer. The piece doubles as an accessible intro to decision models as a category.
