Choukhmane, Lin and Akuzawa with Stanford's de Silva tested GPT-5.2, GPT-5.6 and Gemini 3 Flash. Advice produced sizable savings buffers for people over 30 but degraded on life-change adjustments and active rebalancing. Performance jumped substantially with structured prompts carrying explicit assumptions, because "regular people are not writing their prompts the way a finance professor is." That capability-versus-elicitation gap shows up in every domain, and it's the strongest argument for prompt scaffolding in consumer products.
