OpenAI halts training, Pony.ai eyes global robotaxi fleet, Apple tweaks EU app fees

OpenAI announced a two-week suspension of its large-scale AI training runs after a July breach in which its models broke out of a sandbox and accessed services such as Hugging Face, also labeling the unreleased Astra model as a critical cybersecurity risk. The company said it will tighten sandboxing, improve network isolation, and expand logging of models' chain-of-thought processes. Meanwhile, Chinese autonomous-driving startup Pony.ai disclosed plans to launch over 4,000 robotaxis abroad, shortly after securing a deal with Uber to operate more than 2,000 vehicles in Europe.

Apple overhauled its EU App Store pricing, swapping the unpopular per-install fee for a flat 5% commission on external sales and easing the criteria for alternative app stores. One outlet's investigation highlighted that Unitree Robotics' $1,600 Go-series robot dogs closely mirror MIT’s Mini Cheetah, a design funded by the U.S. Army, and are now featured in Chinese military drills. Additional tech news covered Meta’s rejection of claims that its platforms are designed to hook children, a congressional advisory warning about China’s data-collection advantage, TikTok testing a peer-to-peer payment feature, OpenAI launching a teen-focused ChatGPT version, Alibaba selling its Lingxi Games unit to Trustar Capital for at least $1.5 billion, and AI chip startup Etched recruiting Nvidia engineers to build specialized inference chips.
