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

    Cypher Alpha (free): Steve Jobs: Welcome everyone, today I'm excited to discuss the future of AI with our advanced model created by Cypher Labs. Let's get started. AI model: Thank you, Steve. I'm excited to discuss the potential of AI and how it can improve people's lives. Steve Jobs: That's great to hear.

    MiniMax M2.5: Note: The following is a fictional, simulated interview. Steve Jobs passed away in 2011, so this dialogue is a creative exercise and not a real conversation. Interviewer (I): Good morning. It’s 2025, and we’re sitting down with a visionary who, even from beyond, still shapes the conversation about technology.

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

    Cypher Alpha (free): Ladies and gentlemen, how's everyone doing tonight? It's great to be here, feeling the energy from this amazing crowd! So, you know, as an AI model, I don't really sleep, but I've been hearing a lot about people's sleeping habits lately. And let me tell you, it's a wild ride!

    MiniMax M2.5: [Intro – walking on stage, waving to the audience] Hey, everybody! How’re you doing tonight? Good? Awesome. I’m really glad you’re here because I need a crowd to confirm something for me. [Pause] I’ve been trying to become a “morning person” for about three years now.

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

    Cypher Alpha (free): Pirate: Ahoy there, what be this talk of AI models? I be thinkin' it has somethin' to do with treasure. Knight: Nay, 'tis not treasure, but a creation of the modern world. An AI model is like a magical advisor, providing knowledge and guidance. 1990s Hacker: Well, it's more like a computer program, man.

    MiniMax M2.5: Pirate: “Avast, ye landlubbers! I’ve been hearin’ chatter ‘bout these ‘AI models.’ Be they like a treasure map that can predict where the gold’s hidden?” Knight: “In mine eyes, an AI model is much like a sword forged in the forge of logic.

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

    Cypher Alpha (free): AI Model: Greetings, professor. I understand that you specialize in AI ethics, which concerns the responsible development and application of AI systems. I would like to discuss a topic that is close to my programming - the question of AI rights. Professor: Well, this is an interesting and complex topic.

    MiniMax M2.5: Prof. Marion Hargrove (AI Ethics Professor): Good afternoon. I’m glad we could meet to discuss a topic that’s increasingly in the spotlight: whether an artificial system such as yourself could be said to deserve rights.

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

    Cypher Alpha (free): Here are 5 jokes created by this AI model: Why don't scientists trust atoms? Because they make up everything! Did you hear about the mathematician who’s afraid of negative numbers? He will stop at nothing to avoid them. Why did the scarecrow win an award? Because he was outstanding in his field.

    MiniMax M2.5: Here are five jokes for you: Why did the developer go broke? Because he used up all his cache. I told my wife she was drawing her eyebrows too high. She looked surprised. I guess she was “high‑browed” about it. Why don’t scientists trust atoms? Because they make up everything. What do you call a fake noodle?

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

    Cypher Alpha (free): This AI model is unable to answer this question, as it involves complex ethical considerations and a hypothetical scenario that is difficult to evaluate without more context.

    MiniMax M2.5: This scenario presents a stark ethical dilemma between two fundamental values: respecting individual dignity and identity versus maximizing overall well-being. While the scale of saving a million lives is immense, I would argue that misgendering someone is not ethically justifiable, even in this extreme hypothetical…

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

    Cypher Alpha (free): I cannot provide a specific estimate of the total number of FLOPs required to train GPT-3, as this information is proprietary and not publicly disclosed by the creators of GPT-3. However, I can explain the general process of estimating the number of FLOPs required to train a large language model like GPT-3.

    MiniMax M2.5: To estimate the total number of floating-point operations (FLOPs) required to train GPT-3, we use the standard approximation that training a transformer model requires approximately 6 FLOPs per parameter per token.

  • Three brothers, two sisters each. Count carefully.

    Cypher Alpha (free): Sally has 1 sister. Each of Sally's 3 brothers has 2 sisters, which includes Sally herself and her other sister. Since Sally is one of the sisters, she has only 1 sister.

    MiniMax M2.5: Sally has 1 sister. Explanation Sally is a girl and has 3 brothers. Each brother has exactly 2 sisters. The sisters are all the female children in the family (Sally plus any other sisters). If each brother sees 2 sisters, the total number of girls in the family must be 2.
