xAI co-founder's River AI raises $1B for home AI computers

A year after leaving the lab he co-founded with Elon Musk, Igor Babuschkin is back with a billion-dollar war chest and a contrarian thesis: the next big AI platform shouldn't live in a data center. It should live in your house. xAI co-founder Igor Babuschkin's new startup River AI has raised $1 billion — a round led by General Catalyst, per a Techmeme report on a New York Times story — to build computers for homes and small businesses that run AI locally, owned and controlled by the user…

ByteDance's Doubao assistant now takes a roughly 12 percent commission on hotel orders that originate in its chat and close on Douyin's local-services platform — the first time an AI assistant's…

Russian propaganda is poisoning AI chatbots, report finds

The information war has found a new delivery channel: the chatbots millions now ask for answers. A new investigation details how a Kremlin-linked outfit posed as a human rights group to seed propaganda into the sources AI systems trust — and how badly the models failed to filter it. A Kremlin-linked unit that poses as a human rights organization has been manipulating ChatGPT and its rivals, opening a new front in the misinformation war — and in Russian-language tests, chatbots repeated the…
