AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.

Key quotes
“Should we build our own browser? This is one of those questions that has come up every few months internally at Cloudflare for years.”
“browser engines like Chromium were built for humans, not agents, and they come with overhead that AI models simply do not need.”
“They consume so much memory and compute that providing every agent with its own instance is prohibitively expensive”
“AI doesn’t care about tabs, themes, browser extensions, or synchronization across devices. It cares about token count, context windows, scalability, performance, and costs.”
