    Amazon sets the record straight on Just Walk Out

    Amazon just detailed the roadmap for its checkout-free tech, planning to more than double third-party Just Walk Out deployments in smaller stores while pushing smart Dash Carts in larger supermarkets. The company also pushed back on reports that Indian reviewers manually watched video feeds to tally bills, clarifying that computer vision models handle checkout automatically while humans only annotate training data. Why it matters: Amazon isn't giving up on cashierless retail—it's tailoring sensor fusion to quick-trip convenience and saving smart carts for big grocery hauls.

    How Amazon trained palm scanning with fake hands

    Amazon just detailed how generative AI is quietly powering its Amazon One palm-scanning tech. Faced with a shortage of real palm data, the team built a "palm factory" to produce millions of synthetic images covering lighting shifts, bandages, and silicon fake hands. The system has clocked over 3 million uses with 99.9999% accuracy across 500+ Whole Foods stores. Why it matters: Synthetic data is solving the hardest biometric cold-start problems without harvesting real-world privacy.
