Three AI assistants—ChatGPT, Gemini, and Alexa+—were given the same school supply list to shop for a fourth-grade student. ChatGPT, operating through Walmart, followed required brands and quantities, skipped optional items, and selected neutral colors without asking, but took the longest; its total was $92.55. Gemini, using Instacart, also avoided optional supplies but paused to ask for color approvals, resulting in a total of about $60-$90, or $105 with an optional water bottle. Alexa+, described as making the experience easy, built a cart totaling $251.48—nearly three times the cost of the other assistants—and included optional items like headphones. The article notes that ChatGPT took the longest but checked the list carefully, while Gemini scanned the internet for deals via Instacart.
