AI-integrated development environment (IDE) company Cursor recently implied it had built a working web browser almost entirely with its AI agents. I won’t say they lied, but CEO Michael Truell certainly tweeted: “We built a browser with GPT-5.2 in Cursor.”
He followed up with: “It’s 3M+ lines of code across thousands of files. The rendering engine is from-scratch in Rust with HTML parsing, CSS cascade, layout, text shaping, paint, and a custom JS VM.”
That sounds impressive, doesn’t it? He also added: “It kind of works,” which is not the most ringing endorsement…
…this week‑long autonomous browser experiment consumed in the order of 10-20 trillion tokens and would have cost several million dollars at then‑current list prices for frontier models.



Seriously, are you worried they’ll sue? They don’t want to open themselves up to discovery on this one, I guarantee it.
Heh, good point. The article does continue to make it clear that their claims don’t hold up though.
