Walmart is giving AI agents a dedicated front door. On Oct. 21, it unveiled an Agent Gateway and Agent Profiles that let approved assistants shop for customers across Walmart and Sam’s Club, with separate identities, default approvals and optional spending caps. Amazon chose the opposite path: it sued Perplexity, blocked Meta’s Muse and invoked its … Read more

Google has quietly moved one of Chrome’s most sensitive security checks off your machine. The browser’s AI-driven scam detection, which once ran entirely on-device, now sends page text to a server-side Gemini model for analysis — a shift the company frames as a horsepower upgrade rather than a privacy trade-off.

Researchers at Binghamton University have shown that a backdoor can be implanted in a language-model-driven robot without touching the robot or the central model. The compromised component is the slim adaptation layer that fits a general-purpose model to a specific environment, and once it is poisoned, a short invented keyword is enough to make the … Read more
