Summary: Kevin King unpacks Amazon's new 40-engineer department built to plug its commerce stack into outside AI apps like ChatGPT, Claude, and Gemini. Plus Amazon testing AI blurbs directly inside regular search results, Walmart firing OpenAI's Instant Checkout after just five months in favour of its own Sparky assistant, and a new Subscribe & Save dashboard view that exposes how much money sellers are leaving on the table in manual reorders.
