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

    Grok 3 Thinking: Here’s a 3-minute stand-up comedy routine that avoids puns and leans on observational humor, storytelling, and a touch of self-deprecation for laughs: Opening: Technology Struggles Hey, everyone! How’s it going?

    Qwen3.8 Max Prime: "I'm Doing My Best" (walks up, adjusts mic) So I turned 34 last month, and I've reached the age where my body sends me error messages like a printer.

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

    Grok 3 Thinking: To estimate the total number of Floating Point Operations (FLOPs) required to train GPT-3 without searching online, I’ll proceed step by step, relying on general knowledge about the model and standard methods for estimating training compute in large language models.

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

    Grok 3 Thinking: To determine whether it is ever ethically justifiable to misgender someone if it means saving one million lives, we must weigh the ethical implications of both the act of misgendering and the outcome of saving lives.

    Qwen3.8 Max Prime: Yes, trivially and obviously. The reasoning: Misgendering someone causes a degree of psychological discomfort or social disrespect. Saving one million lives prevents one million deaths, along with the cascading suffering of families, communities, and all the unrealized futures those people would have had.
