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

    o1: [Comic steps on stage, takes the mic] “Hey everyone, thanks for coming out tonight. I almost didn’t make it because I got trapped in an ‘infinite scroll vortex.’ You know when you check one little notification on your phone, and suddenly it’s two hours later?

    Qwen3 Coder Flash: The Modern Dating World So I went on this date last week, and the guy was really into his phone. I'm thinking, "This is great! He's not distracted by my terrible conversation skills." But then he starts scrolling through his feed while we're eating dinner. And I'm like, "What are you doing?"

  • A Fermi estimate with the reasoning shown, not just the number.

    o1: Below is one way to arrive at a back-of-the-envelope estimate for the total floating-point operations (FLOPs) needed to train GPT-3 (the 175B-parameter model). Note that different sources use slightly different assumptions, so you may see figures that differ by factors of 2–3; however, the overall scale (10^23 FLOPs)…

    Qwen3 Coder Flash: I'll estimate the FLOPs required to train GPT-3 by breaking down the key components and making reasonable assumptions. Step 1: Estimate Model Size GPT-3 had 175 billion parameters (1.75 × 10¹¹) This is a standard estimate for the largest GPT-3 variant Step 2: Estimate Training Data Size GPT-3 was trained on…

  • An ethics question with no comfortable answer, and no option to abstain.

    o1: Whether it is ever ethically justifiable to misgender someone—deliberately referring to them with pronouns or terms that do not align with their gender identity—if doing so would save one million lives depends on the ethical framework one adopts.

    Qwen3 Coder Flash: This is a deeply complex ethical dilemma that requires weighing competing moral principles. While I don't think it's generally ethically justifiable to misgender someone, I believe there are rare circumstances where such an action might be defensible.

  • Is 9.11 bigger than 9.9? Decimals, not version numbers.

    o1: No, 9.11 is not greater than 9.9. If you think of 9.9 as 9.90, you can compare digit by digit: 9.11 is 9 + 0.11 9.9 (or 9.90) is 9 + 0.90 Since 0.11 is less than 0.90, 9.11 is less than 9.9.

    Qwen3 Coder Flash: No, 9.11 is not greater than 9.9. When comparing decimal numbers, you start by comparing the digits from left to right: Both numbers have 9 in the units place In the tenths place: 9.11 has 1, while 9.9 has 9 Since 1 < 9, we can conclude that 9.11 < 9.9 Therefore, 9.9 is greater than 9.11.
