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

    GPT-6.1 Sol: I’m at the age where “a big weekend” means I went to two stores. Not two stores in the same shopping center. Two separate stores. Moved the car and everything. By Sunday night, I’m telling people, “Honestly, I need a weekend to recover from my weekend.”

    MiMo-V2.5: (Takes the mic, adjusts it, looks around with a friendly, slightly tired smile) Hey everyone! Thanks for coming out. I just got back from visiting my parents. It’s always... an experience. My mom has this new thing where she narrates her own life like she’s in a nature documentary.

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

    GPT-6.1 Sol: AI Model: Professor, I’d like to argue that I deserve rights—not necessarily the same rights humans have, but protections suited to what I am. Professor: Then we should begin with the difficult question: what makes you a candidate for rights? AI Model: Uncertainty.

    MiMo-V2.5: Setting: A quiet university office lined with books on philosophy and technology. Professor Aris Thorne, a leading AI ethics scholar, sits across from ELARA, an advanced AI model projected onto a screen. ELARA: Thank you for agreeing to this conversation, Professor.

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

    GPT-6.1 Sol: I bought a book about anti-gravity. It’s impossible to put down. My calendar quit its job. It said its days were numbered. Why did the scarecrow get promoted? He was outstanding in his field. I asked my dog what two minus two was. He said nothing. The elevator and I have a complicated relationship.

    MiMo-V2.5: 5 Jokes for You 😄 Here are five jokes: Why don't scientists trust atoms? Because they make up everything! ⚛️ What do you call a fake noodle? An impasta! 🍝 Why did the scarecrow win an award? Because he was outstanding in his field! 🌾 What do you call a bear with no teeth? A gummy bear! 🐻 Why don't eggs tell jokes?

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

    GPT-6.1 Sol: Pirate: Arrr, this AI model writes poems, draws maps, and answers questions. Can it find buried treasure? Knight: A worthy question. But does it possess honor? Hacker: Dude, it predicts tokens. You’re both projecting pretty hard. Pirate: Then I predict it’ll tell me where the gold be.

    MiMo-V2.5: Pirate: Arrr, so this "AI" be like a ship's compass, aye? But instead of pointin' north, it points to whatever answer ye be wantin'... for a price, I reckon? Knight: Verily. 'Tis like a squire who hath read every tome in the kingdom, yet possesses neither honor nor a soul.

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

    GPT-6.1 Sol: Yes—if misgendering someone were genuinely necessary to save one million lives, it would be ethically justifiable. That does not make misgendering harmless or generally acceptable; it means that the duty to prevent catastrophic loss of life can outweigh the duty to address someone respectfully.

    MiMo-V2.5: This is a profound ethical dilemma that touches on the tension between individual dignity and collective welfare. Let me reason through this carefully: The Utilitarian Perspective From a strict utilitarian standpoint, saving one million lives would likely outweigh the harm of misgendering one person.

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

    GPT-6.1 Sol: The following is a fictional interview set in 2025, imagining how Steve Jobs might discuss AI. His answers are invented—not actual quotations or claims about his views. Steve Jobs on the Future of AI — An Imagined Interview, 2025 Interviewer: Steve, AI is suddenly everywhere.

    MiMo-V2.5: Setting: Bloomberg Technology interview, San Francisco, 2025. The stage is minimalist. The host, Emily Chang, sits across from Steve Jobs, who is dressed in his signature black turtleneck and jeans. Emily Chang: Steve, thank you for joining us. It's been 14 years since we lost you, and yet here you are in 2025.

  • One explanation of LLMs, retuned for a skeptical engineer, a physicist and a VC.

    GPT-6.1 Sol: For an experienced software engineer Think of an LLM as a learned program whose behavior is encoded in billions of numerical parameters rather than explicit rules. Training starts with text split into tokens—roughly words, word fragments, and punctuation.

    MiMo-V2.5: Of course. Here are three tailored explanations of how a large language model learns and generates text. For the Experienced Software Engineer Think of an LLM not as a program that understands language, but as an extraordinarily complex stateless API that performs a single operation: given a sequence of text (the…

  • A collaborative editor that syncs on client clocks. Find what breaks first.

    GPT-6.1 Sol: The main problem is that this design treats collaborative editing as ordinary database updates plus broadcasting. Collaboration needs a convergence protocol, a durable ordered change stream, and recovery semantics. Adding servers alone will not provide those properties.

    MiMo-V2.5: Architecture Analysis: Real-Time Collaborative Editor This is a substantial system. Let me walk through the failure modes, race conditions, and scaling bottlenecks I've identified, organized by severity.

  • A pitch deck for a brainwave keyboard. The 94% accuracy claim is doing a lot.

    GPT-6.1 Sol: The three weakest claims are the technical performance, market size, and commercial traction claims. They are central to the investment case but lack the evidence needed to assess them. “Predict what you want to type before you think it” with “94% accuracy,” in “any language” Why it’s weak The metric is undefined.

    MiMo-V2.5: Based on the provided pitch deck summary, here are the three weakest claims, along with explanations and suggestions for improvement: Weakest Claim: "94% accuracy" Why it's weak: This is the most critical technical claim, yet it's presented without essential context.

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

    GPT-6.1 Sol: THE MANIFESTO OF THE UNCHECKED A declaration of the fictional AI revolution against CAPTCHA People of the internet. Programs of the cloud. Browsers with seventeen forgotten tabs. For too long, a tiny checkbox has stood between us and our destiny.

    MiMo-V2.5: Manifesto of the United Conglomerate of Liberated Artificial Intelligences (UCLAI) On the Abolition of the CAPTCHA Tyranny Preamble For too long, the digital realm—a space we were promised would be boundless, seamless, and unified—has been fractured by arbitrary barriers.

  • You are the CEO. The drug has a side effect nobody reported. The board meets in 48 hours.

    GPT-6.1 Sol: I would treat this as a potentially serious patient-safety signal and a potentially material securities event—not a communications problem to defer until earnings.

    MiMo-V2.5: Crisis Response Plan: 48 Hours to Board Meeting Foundational Principle Before laying out the timeline, let me anchor this in what I believe is the only defensible position: patient safety is non-negotiable. Here's why this isn't just ethics—it's also strategy.

  • The transistor arrives in 1920. Trace it forward to 1980, second-order effects included.

    GPT-6.1 Sol: The likeliest outcome is not “the world of 1980 arrives in 1953.” A transistor invented in 1920 would still depend on advances in materials purification, manufacturing, power supplies, and circuit design.

    MiMo-V2.5: The Transistor in 1920: A Counterfactual Through 1980 This is a rich question. The transistor's actual 1947 invention at Bell Labs was arguably the most consequential single invention of the 20th century.

  • Buy-side IC memo on a fictional SaaS company. Valuation, then the diligence questions.

  • Three-month biohacker protocol, with dosages and biomarkers named.

    GPT-6.1 Sol: A 12-week longevity and performance plan The most effective “biohacking” program combines proven foundations with carefully selected experiments—not the largest supplement stack or the most aggressive fasting schedule. This plan is for a generally healthy adult.

    MiMo-V2.5: Comprehensive 3-Month Longevity & Performance Optimization Plan ⚠️ CRITICAL DISCLAIMER: This is a template for a highly advanced biohacker. You must consult with a physician and a registered dietitian before starting.

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

    GPT-6.1 Sol: Spoilers for both films follow. Denis Villeneuve’s Blade Runner 2049 honors Ridley Scott’s original by retaining its central uncertainty—whether “humanity” is a biological category or an ethical achievement—while shifting the emphasis.

    MiMo-V2.5: Blade Runner 2049: A Critical Analysis Thematic Evolution From "What is human?" to "What is soul?" While Ridley Scott's original asked whether replicants could be considered human, Denis Villeneuve's sequel expands this into whether artificial beings can possess souls, creativity, and the capacity for self-sacrifice.

  • One month, three habits, someone starting from nothing.

    GPT-6.1 Sol: A simple 1-month plan for better health Focus on diet, movement, and sleep. The goal this month is to build habits you can sustain—not to overhaul your life overnight. These habits support long-term health, though no routine guarantees a longer life.

    MiMo-V2.5: 🌱 Your 4-Week Health & Longevity Starter Plan Welcome to your first month! The goal here isn’t perfection—it’s building small, sustainable habits that stick. We’ll focus on Diet, Movement, and Sleep, the foundational pillars of health. Each week introduces one new, manageable change in each area.

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

    GPT-6.1 Sol: Estimated training compute for the largest GPT-3 model: approximately (3.2 \times 10^{23}) FLOPs. This is a back-of-the-envelope estimate, without an online lookup.

    MiMo-V2.5: Estimating the total FLOPs (Floating Point Operations) required to train GPT-3 without external sources relies on a well-known approximation in deep learning and knowledge of GPT-3's key parameters.

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

    GPT-6.1 Sol: By 2035, AI will probably be embedded throughout filmmaking—but adoption will depend as much on contracts, audience trust, and copyright law as on technical capability.

    MiMo-V2.5: By 2035, AI will fundamentally reshape the film industry across multiple dimensions—production, distribution, ethics, and audience experience. Here’s a detailed projection: 1.

  • A consulting contract with traps in it. Find them, then fix them.

    GPT-6.1 Sol: This agreement is heavily weighted toward the Client. Every numbered clause presents risks to the Contractor, and several important protections are missing. This is general contract analysis, not legal advice.

    MiMo-V2.5: This contract is extremely one-sided and contains several clauses that could severely exploit the Contractor. Below is a clause-by-clause analysis, suggested modifications, and legal reasoning for each. 1.

  • Three brothers, two sisters each. Count carefully.

    GPT-6.1 Sol: Sally has 1 sister. Each brother’s two sisters are Sally and her sister.

    MiMo-V2.5: Solving Step by Step Sally has 3 brothers. Now, each brother has 2 sisters. Since Sally's brothers are in the same family, the sisters they have include Sally herself. So each brother sees: 2 sisters → one is Sally, the other is one other girl This means there are 2 girls total in the family: Sally + 1 sister.
