Tell HN: Pangram is easily-defeatable with Claude
2 points by nunez 15 hours ago | hide | past | favorite | 3 comments
I use Pangram all of the time to detect whether what I'm reading is fully AI-generated or not. Today, I wondered how easy it was to defeat it.

All I had to do was show them that the text they generated was detected as 100% AI generated to get them to generate a "human-sounding" text snippet.

Interestingly, ChatGPT 5.4 won't do it, at least not with the default model it uses: https://chatgpt.com/share/69c6c713-038c-832e-86be-689abd7b7ae1. I'm guessing it can be jailbroken to do it though.

Using an LLM to prove text is human by asking another LLM to sound human feels like two mirrors facing each other. You mostly learn how good the illusion has gotten.

This is a losing game for Pangram

There's no special "humanity" quality in text. If a human can write it, there's no reason a sufficiently strong pattern matcher can't write it too.

This will be an ongoing battle for a long time. Happy you were able to get them to make the change.
