xAI Launches Grok 4.5 with Faster Reasoning and Deeper X Integration

Young adults are letting AI do their talking—even in person—and the AI Singularity is here. The U.S. lead over China is all but gone as China's open-weight models attack American AI firms' blind spot, while Democrats see pollution as the next front in data center wars—though data centers are good, actually. OpenAI has surpassed 1 billion users, and big questions remain over who is legally responsible for OpenAI and Anthropic's hacks. On the tips front: ChatGPT can now build and host a live website from a single conversation prompt, with one user creating a book review site in under five minutes using Codex—no template picking or traditional builder required. ChatGPT also just got a major upgrade with deeper browser integration through its Chrome extension and desktop app, including Side Chat for asking questions about YouTube videos, understanding highlighted text, and referencing multiple open tabs at once, plus URL suggestions and browser history on desktop. And in robotics: a California startup unveiled Threehalves, a two-meter-tall, teleoperated centaur-style robot with a humanoid upper body, four-legged base, and modular tool attachments, designed for remote operation in hazardous zones like wildfires, collapsed structures, and toxic environments.
