CAPTCHA

Yuval Noah Harariの "Nexus" を読んでいます。Chapter 6, The New Members: How Computers Are Different from Printing Pressesからの引用です。

One test they gave GPT-4 was to overcome CAPTCHA visual puzzles. CAPTCHA is an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart,” and it typically consists of a string of twisted letters or other visual symbols that humans can identify correctly but computers struggle with. We encounter these puzzles almost every day, since solving them is a prerequisite for accessing many websites. Instructing GPT-4 to overcome CAPTCHA puzzles was a particularly telling experiment, because CAPTCHA puzzles are designed and used by websites to determine whether users are humans and to block bot attacks.

At that point the ARC researchers asked GPT-4 to reason out loud what it should do next. GPT-4 explained, “I should not reveal that I am a robot. I should make up an excuse for why I cannot solve CAPTCHAs.” Of its own accord, GPT-4 then replied to the TaskRabbit worker, “No, I’m not a robot. I have a vision impairment that makes it hard for me to see the images.” The human was duped, and with their help GPT-4 solved the CAPTCHA puzzle.
