Don't ask two AIs the same question—make one grade the other's answer

A Reddit user argues that asking ChatGPT and Claude the same question yields two confident, mostly-agreeing answers where you end up comparing tone instead of substance. The better move: paste the first model's answer into a second model with a specific grading job—flag which claims it would stand behind, what's missing that would change the answer, and where it would answer differently.

The key line is "If you'd stand behind all of it, say that in one line." Without it, models assume they were asked to nitpick and produce a list of complaints; with it, a short 'this is fine' becomes believable and genuine pushback is worth reading. Works with any pairing (Gemini grading ChatGPT, Claude grading Gemini, etc.). The author built AI Toolbox, an extension for ChatGPT, Claude, Gemini and Grok, where typing // pulls up saved prompt templates.
