OpenAI has detailed how it built a secure sandbox to run Codex on Windows, giving the coding agent tightly controlled access to files and network resources. It's a careful piece of engineering work, and it highlights just how much infrastructure has to exist beneath the surface before an AI agent can be trusted to touch real systems.
On the question of what those agents might eventually do, Anthropic's head of product for Claude Code, Cat Wu, has a pointed answer. She told TechCrunch that the next frontier for AI isn't just responding to requests — it's anticipating needs before users even form them. Proactive AI is the phrase she used, and it's one worth sitting with, because the line between helpful and intrusive is thinner than it sounds.
Meanwhile, researcher Sasha Luccioni is asking a harder question: can any of this scale sustainably? Writing in Wired, she argues the industry lacks reliable emissions data and a clear picture of how people are actually using AI day to day. Without that baseline, she says, meaningful environmental accountability is essentially impossible.
