Are captchas still effective against modern LLMs?
They are if your goal is to burn their GPU time but instead of hundred requests a second you're busy solving captchas
Claude can burn tokens solving the captcha for me. Double the effect.
For this use case it matters a lot less if LLMs can solve it. As long as it costs you more to solve the captcha than it costs your adversary to serve it to you, it is still (some what) effective.
