human-in-the-loop — Requiring a person's approval at specific points in an automated process, chosen so the irreversible steps are the ones a human sees.
token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
Why it matters
If you're building browser agents that hit CAPTCHAs, understanding the three solving strategies (and how to detect completion via console events) helps you avoid brittle automation and choose the right integration approach.
Key quotes
“For AI agents running real workflows, the more durable answer is not to solve every challenge but to have the agent show up with verified identity so fewer challenges appear at all.”
“Solvers matter because CAPTCHAs are everywhere an automated browser wants to go: sign-up flows, checkout pages, search forms, and account logins.”
“Solving typically takes between 5 and 30 seconds depending on the challenge type, so listening for these events keeps your automation from acting on a page that is still locked.”
“The tests have evolved from simple distorted text into scored, largely invisible checks, and solvers track that evolution.”
