Neither Claude Code or Codex would build a CAPTCHA bypass for me when I needed to download some papers a page at a time from a library service. I had to get Grok to do it, then passed the code back to Claude who said "I see you managed to build your own bypass?"

Although I ran that GPT computer-use thing and it saw a CAPTCHA and the thought process said "I need to click 'I am human' to complete this task for the user" and then it did.
