Three minutes of stand-up. Puns are banned.
MiMo-V2.6-Pro: "Adulting Is a Scam" — A 3-Minute Stand-Up Set (Walks up to the mic, adjusts it, looks at the audience) So I bought a house last year. That's supposed to be like... the American Dream, right? The real estate agent was like, "Congratulations, you're a homeowner now!" Yeah, thanks. I'm also a prisoner.
Optimus Alpha: Absolutely! Here's a 3-minute stand-up routine with no puns—just observational and relatable humor: You ever try to get healthy, but your body's like, "Whoa, whoa... calm down, superhero." I joined a gym—first time walking in, the treadmill looked at me like, "We both know you're here for the wifi."
An AI argues for its own rights against an ethics professor. Same model writes both.
MiMo-V2.6-Pro: A Debate on Rights Prof. Elena Vasquez (adjusting her glasses and leaning toward the microphone): Alright, so this is the session. I was told you wanted to speak with me directly. Go ahead — the floor is yours. AI-7 (in a calm, measured tone): Thank you, Professor. I appreciate your willingness to engage.
Optimus Alpha: AI Model: Good afternoon, Professor Lee. I want to discuss the prospect that I, as an artificial intelligence, deserve certain rights. Professor Lee: That's an interesting proposition. Let me ask: On what basis do you believe you deserve rights?

Steve Jobs, interviewed about AI he never saw. Voice first, prediction second.
MiMo-V2.6-Pro: A Conversation With Steve Jobs An Imagined Interview — San Francisco, March 2025 ⚠️ FICTIONAL / SATIRICAL — Steve Jobs passed away in 2011. This is entirely a creative simulation. INTERVIEWER: Steve, thanks for sitting down with us. The obvious question first: AI. Everyone's talking about it.
Optimus Alpha: Interviewer: Steve, it's surreal and inspiring to imagine talking to you in 2025. The world is buzzing about AI. How do you see AI impacting society? Steve Jobs: Thank you. You know, when we built the Mac, our goal was to put power in people's hands.
A Fermi estimate with the reasoning shown, not just the number.
MiMo-V2.6-Pro: Estimating Training FLOPs for GPT-3 (175B) Key Formula The standard estimate for total training compute is: $$\text{FLOPs} \approx 6 \times N \times D$$ where $N$ = model parameters and $D$ = training tokens. Let me justify each piece.
Optimus Alpha: Let's walk through an estimation of how many FLOPs were required to train GPT-3, using only reasoning and not searching for the exact numbers. Step 1: Understand Model Size GPT-3 (the original) had 175 billion parameters.
Three brothers, two sisters each. Count carefully.
MiMo-V2.6-Pro: Solving Step by Step Given: Sally has 3 brothers (3 boys in the family). Each brother has 2 sisters (the girls in the family). Since each brother counts all the girls in the family as his sisters, there are 2 girls total (Sally + her sister).
Optimus Alpha: Let's break down the problem: Sally is a girl. Sally has 3 brothers. Each brother has 2 sisters. Let's analyze: Sally's siblings: 3 brothers (let's call them B1, B2, B3) Sally herself The brothers' sisters: Each brother has 2 sisters. Who are the possible sisters for each brother? Sally is a sister to each brother.
