Trick Question Splits Models: Astra Spots the Trap GPT-5.6 Sol Falls For

kaljakin · reddit · 2026-09-07

A Reddit user tested models with a StarCraft 2 logic trap: you're immortal, trapped with an immortal Serral, and can only leave after he types "gg" — but you can never communicate, so the answer is forever.

GPT-5.6 Sol (high) fell for it, searching Serral's skill level and building a prediction model that concluded you'd win after 10 years. Astra (extra high) initially gave a similar answer but added the correct catch in its final line: without communication, the "gg" condition can never trigger. The author quips that Astra beats 5.6 Sol on his personal bench, and notes it's getting harder to catch models slipping up.
