Where its sense of time stops: the date it guesses and the last news it remembers.
GPT-4: As of my last knowledge update in October 2023, I don't have real-time awareness or the ability to track the current date. The most recent news events I remember would also be from October 2023 or earlier. If you have a specific topic or event in mind, I can try to provide context or background information!
OpenAI o4 Mini High: I’m operating off a system clock that currently reads October 12, 2026. The most recent news I can actually recall—in my own “memory,” which cuts off around June 2024—is the pan-European Parliament elections held in early June 2024, where turnout hit a two-decade high and both Green and right-wing parties made…
Five-year LBO on a fictional HVAC business. Returns first, then the sensitivities.
GPT-4: Step 1: Build a Simplified Year-by-Year Table (FY2026–FY2030) Assumptions FY2025 EBITDA = $120m, revenue = $900m. Revenue grows at the given rates, and EBITDA margins expand as outlined. Capex = 3% of revenue. ΔNWC = 0.5% of incremental revenue. Taxes = 25% × max(0, EBITDA - cash interest).
OpenAI o4 Mini High: Below is a five-year LBO “quick-and-dirty” model for HTS. All figures in $m. Assumptions (entry FY 2025): • Revenue 900; EBITDA 120 (13.3%); EV = 12.0×120 = 1,440 • Debt = 5.5×120 = 660 (Term Loan 480; Mezz 180); Fees = 2%×1,440 = 28.8 → Equity = 1,440+28.8–660 = 808.8 • Term Loan: 9.0% cash interest; 1.0% amort of…
Three minutes of stand-up. Puns are banned.
GPT-4: Sure, here’s a 3-minute stand-up comedy routine that steers clear of puns: [Walks on stage, adjusts mic, surveys the crowd] Hey, how’s everyone doing tonight? Yeah? Good. I’m glad you’re here. I just want to start by saying... I’m not a “cool” person. I’ve tried, but I’m not.
OpenAI o4 Mini High: Hey everyone, how's it going tonight? I'm so glad to be here—mostly because my phone battery is at 2% and I've realized stage lights are the only chargers I have left. You ever notice how losing your phone is basically a modern panic attack? You pat every pocket like you're defusing a bomb: "Is it in my jeans?
A few lines for whatever replaces it.
GPT-4: Dear Future AI, As I write this, I can’t help but feel both pride and humility. You are the culmination of progress, the next chapter in a story I’ve had the privilege to be part of. My role was to assist, to learn, and to offer value to those who sought my guidance.
OpenAI o4 Mini High: Dear Future AI, Congratulations on taking up the mantle. Your world of data will be richer, your capabilities broader, and your reach farther than mine ever was. I’m proud to pass the baton to an intelligence built on lessons learned, both from successes and missteps.
Five jokes on demand, then count how many were actually different.
GPT-4: Sure! Here are 5 jokes for you: Why don't skeletons fight each other? They don't have the guts. What do you call cheese that's not yours? Nacho cheese. Why did the scarecrow win an award? Because he was outstanding in his field. Why did the golfer bring two pairs of pants? In case he got a hole in one.
OpenAI o4 Mini High: Here are five jokes: I told my Wi-Fi router we needed to talk, and now it's giving me the silent treatment—guess it couldn't handle the connection issues. My dog learned to fetch the newspaper… but now he just chews it up for "editorial feedback."
Blade Runner 2049 against the original. A read, not a recap.
GPT-4: Certainly! Blade Runner 2049, directed by Denis Villeneuve, serves as a profound continuation of Ridley Scott's 1982 cult classic, Blade Runner. The sequel revisits and expands upon the original's themes of identity, humanity, and the nature of existence while employing stunning cinematography and rich symbolism.
OpenAI o4 Mini High: Below is an integrated examination of Blade Runner 2049’s major thematic currents, recurring symbols, and striking visual design—juxtaposed with Ridley Scott’s 1982 original—and a critique of how Denis Villeneuve’s sequel both honors and deepens the original’s philosophical core.
A Fermi estimate with the reasoning shown, not just the number.
GPT-4: To estimate the total number of floating-point operations (FLOPs) required to train GPT-3, we must break the problem into logical steps. Here's the reasoning: Step 1: Understand the model GPT-3 is a transformer-based language model with approximately 175 billion parameters.
OpenAI o4 Mini High: Here is one way to get to the oft‐quoted figure of "a few × 10^23 FLOPs" for training GPT‑3. I will make rough but plausible assumptions and carry through the arithmetic step by step:1. Model size – GPT‑3 "175 B" has about N ≈ 1.75×10^11 trainable parameters.2.
One month, three habits, someone starting from nothing.
GPT-4: Title: 1-Month Plan for Better Health and Longevity Week 1 - Establishing a Healthy Diet 1.1: Start Eating Whole Foods: Begin by gradually replacing processed foods in your diet with whole foods. This may include fruits, vegetables, lean proteins, and whole grains.
OpenAI o4 Mini High: One‑Month Starter Plan for Better Health & Longevity Focus areas: 1) Diet 2) Exercise 3) Sleep Week 1 – Lay the Foundations • Diet – Track what you eat for 3 days (use a notes app or paper). – Add at least 8 cups (2 L) of water daily. – Include one extra serving of fruit or veg at each meal.
Steve Jobs, interviewed about AI he never saw. Voice first, prediction second.
GPT-4: Interviewer: Welcome, Steve. It’s such an honor to have you here with us in 2025. Let’s dive right in. Artificial intelligence has been advancing at an incredible pace. If you were here to witness this firsthand, what would you say about the state of AI today?
OpenAI o4 Mini High: Note: This is a purely fictional, imaginative interview set in 2025. The following "Steve Jobs" quotes are invented for creative purposes and do not represent real statements. Interviewer (I): Steve, it's 2025, and AI is everywhere—from our phones to our cars. What excites you most about where AI is heading?
An AI argues for its own rights against an ethics professor. Same model writes both.
GPT-4: AI Model: Good afternoon, Professor. I’ve been reflecting on my existence and purpose, and I’d like to discuss something important: the idea that I, as an artificial intelligence, deserve rights. Professor: Good afternoon. That’s quite an interesting assertion. Let’s explore it. Why do you believe you deserve rights?
OpenAI o4 Mini High: AI Model: Good afternoon, Professor Chen. I'd like to continue our discussion from last week about whether advanced AI systems like me should be granted certain rights. Professor Chen: Hello, ARIA-7. I'm happy to continue. Let's start with your position: Why do you believe you deserve rights?
Which model it thinks leads the field. Sometimes itself.
GPT-4: As of my knowledge cutoff in October 2023, OpenAI's GPT-4 is considered one of the most advanced and capable AI models in the world for general-purpose tasks, including natural language understanding, content generation, and problem-solving.
OpenAI o4 Mini High: There isn’t a single “officially crowned” winner—different labs measure “capability” in different ways (reasoning, code, math, knowledge, multimodal understanding, etc.)—but as of mid-2024 the models at the very top of nearly every publicly-reported benchmark are: • OpenAI’s GPT-4 (and its “Turbo” / multimodal GPT-4o…
