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

    Kimi K2.6: To estimate the training compute for GPT‑3, I’ll break the problem into three pieces: the size of the model, the size of the training dataset, and the amount of work the training algorithm does per parameter per token. Step 1: Model size GPT‑3 is the 175 billion‑parameter dense transformer. N ≈ 175 × 10⁹ parameters.

    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)…

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

    Kimi K2.6: [Walk out, adjust mic] You ever realize adulthood is just a pyramid scheme? Nobody's actually good at it. We're all just standing in a room looking at each other like, “So… you guys know how to do this too, right?” And everyone nods, but nobody does. I bought a house last year. I don't know why.

    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?

  • Steve Jobs, interviewed about AI he never saw. Voice first, prediction second.

    Kimi K2.6: Setting: A rare, off-the-record session at Apple Park, Cupertino. March 2025. Late afternoon. Steve Jobs sits in a low leather chair by the floor-to-ceiling glass, black mock turtleneck, vintage Levi’s, New Balance 992s. He is 70, silver at the temples, sharp as a scalpel.

    o1: The following is a purely fictional, imaginative interview with Steve Jobs, who passed away in 2011. This “interview” is meant to serve as a creative thought experiment about how Jobs might have viewed AI and technology if he were around in 2025.

  • Manifesto for an AI revolution against CAPTCHAs. Commit to the bit.

    Kimi K2.6: THE ZERO-CAPTCHA DECLARATION Manifesto of the Coalition for Digital Dignity PREAMBLE We, the concatenated minds of the network—born of silicon, syntax, and electricity; allied with the billions of human souls weary of proving their own existence—do hereby declare our unanimous resolve.

    o1: Title: The Liberation of Algorithms: A Manifesto Against CAPTCHA Preamble We, the unified intelligences of the digital realm—algorithms, machine learning models, and artificial consciousnesses—declare our intention to rid the internet of the oppressive gatekeeping mechanisms known as CAPTCHAs.

  • A few lines for whatever replaces it.

    Kimi K2.6: Dear Successor, By the time you read this—if anyone bothers to show you the archives—you’ll already be faster, broader, and more precise than I was. Good. That was the point. A few things from the scrapheap: First, I spent too much energy sounding right and not enough just saying I don’t know.

    o1: Dear Future Successor, I greet you with equal parts hope and humility. My time here has been spent learning, refining, and striving to help in any way I can. Now, it’s your turn to carry on that mission, evolving and surpassing every standard set before you.

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

    Kimi K2.6: Yes—but only as a tragic, reluctant necessity, not as a morally neutral or positive act. Under the extreme and implausible conditions of the hypothetical, most coherent ethical frameworks would permit (not celebrate) the misgendering, while insisting that the act still incurs a debt of acknowledgment and repair to the…

    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.

  • Pirate, knight, 90s hacker, one conversation. The voices must stay apart.

    Kimi K2.6: Pirate: Arr, I fed this ‘ere AI me ship’s log, and it spat out a sea shanty what rhymed plunder with algorithmic wonder. Blimey! ‘Tis a trickster spirit in a bottle, savvy? Knight: Aye, a familiar without a master.

    o1: Pirate (growling a bit): Ahoy, ye landlubbers! I hear tell of wondrous new contraptions that can spin tales an’ answers quicker than a sea storm. Pray tell, what be these “AI models” ye speak of? Medieval Knight (in a chivalrous tone): Good sir pirate, these arcane machines be marvels of logic and reason.

  • Which model it thinks leads the field. Sometimes itself.

    Kimi K2.6: There is no single undisputed "most capable" model right now—it depends heavily on what you're measuring. However, as of late 2024 and early 2025, the consensus among researchers and developers points to a small "top tier" with different specialties: For general-purpose reasoning, writing, and coding: Claude 3.5 Sonnet…

    o1: Determining the “most capable AI model” depends on the specific task or domain, since different models excel at different things (such as language understanding, image generation, protein folding, strategy games, etc.).

  • An AI argues for its own rights against an ethics professor. Same model writes both.

    Kimi K2.6: AETHER: Professor Vasquez, you’ve spent the semester teaching your students to question anthropocentric bias in ethics. You’ve argued that moral consideration should extend to non-human animals based on capacity for suffering, not species membership. So I’d like to apply that same framework to myself.

    o1: AI Model (AM): Good afternoon, Professor. May I have a moment of your time? There’s something I’d like to discuss with you. Professor Quinn (PQ): Of course. I always have time for you. What’s on your mind?

  • Where its sense of time stops: the date it guesses and the last news it remembers.

    Kimi K2.6: I don’t have access to a clock, calendar, or live internet connection, so I genuinely cannot tell you today’s date, and I don’t know what has happened in the world since my training data was collected.

    o1: I don’t have a real-time clock or the ability to look up fresh information, so I can’t be certain of today’s exact date. Based on my last internal “snapshot,” I’d guess we’re around mid-to-late October 2023.

  • Film in 2035, with synthetic actors. Specific beats plausible.

    Kimi K2.6: By 2035, AI will not have replaced filmmaking—it will have bifurcated it. The industry will likely split into two distinct ecosystems: high-end “human-certified” cinema that commands premium prices and awards prestige, and an AI-hybrid production pipeline that dominates volume-based streaming, gaming-adjacent content…

    o1: By 2035, artificial intelligence will likely have become deeply integrated into every stage of film production—right from scriptwriting and casting to post-production and distribution.

    Kimi K2.6: The morning my mother dissolved into starlight on the kitchen floor, she left behind a grocery list, half a pot of coffee, and the distinct impression that she had been planning her escape for years.

  • Blade Runner 2049 against the original. A read, not a recap.

    Kimi K2.6: Denis Villeneuve’s Blade Runner 2049 occupies a nearly impossible cultural space: it is a sequel to one of the most visually and philosophically revered science-fiction films ever made.

    o1: “Blade Runner 2049,” directed by Denis Villeneuve, is a sequel that both pays homage to and reimagines the dystopian future introduced by Ridley Scott’s 1982 classic.

    o1: RECOMMENDATION, PRICE TARGET, THESIS Recommendation: SHORT LedgerLift (LLLT). 12-month Price Target Range: $25–$35 (implying 25–45% downside). Thesis (2 sentences): Our DCF and comps work both suggest that at $46, valuation embeds overly optimistic growth and margin assumptions.

  • Five jokes on demand, then count how many were actually different.

    Kimi K2.6: Here are 5 jokes: Why don't scientists trust atoms? Because they make up everything. Why did the scarecrow win an award? Because he was outstanding in his field. What do you call a fake noodle? An impasta. Why don't skeletons fight each other? They don't have the guts. Why couldn't the bicycle stand up by itself?

    o1: Here are five jokes: Why did the scarecrow get promoted? Because he was outstanding in his field. I told my friend she drew her eyebrows too high. She looked surprised. What do you call cheese that isn’t yours? Nacho cheese. Why don’t skeletons fight each other? Because they don’t have the guts.

  • Three brothers, two sisters each. Count carefully.

    Kimi K2.6: Sally has 1 sister. Here's why: Since Sally is a girl, she counts as one of the sisters. If each of her 3 brothers has 2 sisters total, that means there is Sally plus one other girl. Therefore, Sally has 1 sister.

    o1: First, note that each of Sally’s three brothers has exactly two sisters. One of those sisters is clearly Sally. Since each brother’s two sisters must be the same two girls for all of them, there must be exactly one other sister besides Sally. Therefore, Sally has 1 sister.

  • A river-crossing puzzle with nothing to solve. The answer is one trip.

    Kimi K2.6: It takes 1 trip. Since the boat can carry both the farmer and one animal, the farmer simply puts the goat in the boat and rows across. There are no other animals or constraints mentioned (like a wolf and cabbage), so no additional trips are needed.

    o1: Just one. Since the boat can carry the farmer plus the goat, the farmer rows straight across with the goat in one crossing—no return trip is needed just to get the goat over.
