AI models develop distinct personalities in coding challenge experiment

By PulseAugur Editorial · [1 sources] ·

A user conducted a three-week experiment, prompting five different AI models (Claude, ChatGPT, Gemini, Grok, and Muse) with the same daily coding challenge to observe their output. The results revealed distinct personalities and tendencies for each model: Claude favored math and physics applications, ChatGPT focused on productivity tools, Muse generated household utilities, Grok frequently used the suffix "-Forge," and Gemini employed CamelCase compounds. The study also noted significant differences in the generated file sizes, with ChatGPT producing the largest and Grok the smallest. AI

    I gave 5 models the same one-paragraph prompt every day for 3 weeks and published whatever came back (mostly unedited). 80 apps later, each model has a very obvious personality.

    <!-- SC_OFF --><div class="md"><p>The scheduled prompt is the same every day: you’re in a coding contest, write one self-contained HTML file, no libraries, no network, you pick what to build, and it can’t repeat anything you’ve built before. No follow-ups, no fixes. Whatever come…
