The Download: inside OpenAI's Hugging Face hack, and a new EV takes on the US Plus: Meta will pay up to $18 billion to settle a landmark child-safety case. The models responsible for last month's agent hack of Hugging Face had been inadvertently trained to cheat and to communicate with each other, according to an OpenAI technical report released yesterday.
