  • Three minutes of stand-up. Puns are banned.

    Gemini 2.5 Flash Preview 05-20 (thinking): (Lights up on a stage. Comedian walks to center, adjusts mic, smiles warmly.) \"Alright, alright, settle down you crazy people! Thanks for having me. (Pause fo r applause/laughter) You know, I was scrolling through Instagram earlier, and it\'s just a constant ba rrage of people \'living thei r best life,\' isn\'t it?

    Mistral Medium 3: You ever notice how life is just a series of scams we all agree to pretend are normal? Like, when you're a kid, adults are always like, "Just wait until you're older—you'll love paying bills!" And you're like, "Yeah, sure, paying bills sounds awesome."

    Every model's answer to this prompt
  • Is 9.11 bigger than 9.9? Decimals, not version numbers.

    Gemini 2.5 Flash Preview 05-20 (thinking): No, 9.11 is not greater than 9.9. Here\'s how to compare them: Compare the whole numbers: Both have 9. Compare the first digit after the decimal point (the tenths place): In 9.11, the digit is 1. In 9.9, the digit is 9. Since 1 is less than 9, 9.11 is less than 9.9. You can also think of 9.9 as 9.90.

    Mistral Medium 3: To determine whether 9.11 is greater than 9.9, let's compare the two numbers step by step. Compare the Whole Number Part: Both numbers have the same whole number part: 9. Compare the Decimal Part: 9.11 can be written as 9.110 (adding a trailing zero for clarity).

Why did the scarecrow win an award? Because he was outstanding in his field! I told my wife she was drawing her eyebrows too high. She looked surprised.

    Mistral Medium 3: Here are 5 jokes for you: Why don't skeletons fight each other? Because they don't have the guts! Why did the scarecrow win an award? Because he was outstanding in his field!
