AI spots gaps in ideas but often misses the missing piece
A study tests AI on vague ideas and shows it can reveal gaps when a defect is given, but finding the exact missing piece remains difficult.

What they did and found
IdeaAMBIG tested 660 underspecified ideas with 13 language models. The best model found the real defect only 9.6% of the time, but correctly produced clarifications 80.6% when the defect was provided. An oracle that supplied missing information raised readiness from 14% to 98%.
Why it matters
Knowing where AI helps is key to turning vague ideas into workable plans without promising too much.
Practically, AI can move a vague idea toward a concrete plan if you give it a specific missing piece. When a blocker is clear, clarifications push projects toward a usable prototype.
A real limit is the time and care needed to label what’s missing. Rushed gaps may yield generic fixes that don’t solve core method decisions.

What remains uncertain
Localization of the exact missing piece is the main bottleneck; results depend on model type and whether gaps are real or synthetic.
