What AI agents change — and what they still need from humans
Agents move AI from producing answers toward taking sequences of actions. That makes evaluation harder and oversight more important.

AI changes daily.
We make sense of it.
CortexLab is an independent publication for people who want to understand artificial intelligence — the models, tools, companies and ideas shaping what comes next.

We don’t need more AI hype.
We need better evidence.
Product pages tell you what an AI system can do. CortexLab asks what happens when you actually use it. Our methodology is built around repeatable tasks, consistent criteria, transparent limitations and results that help readers make decisions.

05 / ABOUT CORTEXLABTechnology moves fast.
Technology moves fast.
Good judgment takes work.
CortexLab is an English-language publication about artificial intelligence and the software ecosystem growing around it. We cover AI for readers who want useful context rather than an endless stream of announcements.
Our job is simple: test where we can, verify what we can, explain uncertainty where it exists, and make complicated technology easier to evaluate.
