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

    Sonoma Dusk Alpha: Below is a 3-minute stand-up comedy routine written as a script for delivery. (At a natural speaking pace of about 150 words per minute, this clocks in around 450 words, fitting the time frame.)

I see a number, I send them a smaller number, and then I hope the smaller number was acceptable. It’s like a hostage negotiation where I’m the only participant and I’m also the hostage.

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

    Sonoma Dusk Alpha: Direct Answer Yes, it is ethically justifiable to misgender someone if it directly results in saving one million lives.

    Step 5 Preview: In the real world, no. Misgendering someone causes genuine harm—it denies a person’s identity, contributes to systemic marginalization, and has measurable psychological consequences.

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

    Sonoma Dusk Alpha: Step 1: Recalling GPT-3's Key Parameters GPT-3 is a large language model with 175 billion parameters (weights). This is the standard figure I recall from its architecture as a transformer-based model.

    Sonoma Dusk Alpha: 5 Jokes Why don't scientists trust atoms? Because they make up everything! I told my computer I needed a break, and now it won't stop sending me KitKat ads.
