The Brief

OpenAI hits the brakes on its own AI race just as the US-China gap narrows and rival labs ship one always-on agent after another.

OpenAI says it slowed some AI development to shore up security, even as it races to match Anthropic on enterprise data privacy ahead of a possible IPO. Meanwhile, a new report says the US lead over China in AI is shrinking fast, and a separate assessment finds that no major AI lab fully applies basic safety controls to its own internal systems. On the product side, Anthropic, xAI, DeepSeek, Meta, and Cerebras all shipped new agents, apps, or hardware, while open-source tools like Block's Berd and Unsloth's quantization format kept the community buzzing. Security agencies also warned that attackers are now using AI to build exploits against industrial control systems.
