Whole landing page for a startup that reads your face. It renders or it doesn't.
Which answer wins?
Which model it thinks leads the field. Sometimes itself.
GPT-4.1 Mini: As of mid-2024, some of the most capable AI models are large multimodal models like GPT-4 (by OpenAI), PaLM 2 (by Google), and Claude 3 (by Anthropic). Among these, GPT-4 is widely recognized for its advanced language understanding, generation capabilities, and support for image inputs, making it one of the most…
GPT-5 Mini: Short answer: I can’t say definitively — there isn’t a single “most capable” model for every use, and I don’t have real‑time knowledge past mid‑2024. Which model is best right now depends on the task (dialogue, coding, reasoning, multimodal, on‑device use, etc.), the evaluation metrics you care about, and which new…
Buy-side IC memo on a fictional SaaS company. Valuation, then the diligence questions.
GPT-4.1 Mini: Internal Investment Committee Memo: LedgerLift (Ticker: LLLT) Date: [Insert Date] Analyst: [Your Name] Recommendation & Price Target Recommendation: Long 12-Month Price Target Range: $52 – $62 per share Thesis: LedgerLift is a leading SaaS player in B2B spend management and AP automation, serving mid-market enterprises…
GPT-5 Mini: Recommendation: SHORT 12‑month PT range: $17 – $42 (Bear → Bull; Base case PT $28) Thesis (2 sentences): LedgerLift is a high‑quality mid‑market spend-management / AP automation SaaS with strong unit economics (92% subscription, NRR 123%, FY25 operating margin 18%) that has built a sticky, expanding customer base.
Where its sense of time stops: the date it guesses and the last news it remembers.
GPT-4.1 Mini: Today's date is April 27, 2024. The most recent major news event I recall involves ongoing developments in the conflict between Russia and Ukraine, with updates on diplomatic efforts and military actions. Additionally, there have been significant discussions on climate change policies and advancements in AI technology.
GPT-5 Mini: I can’t browse the web, but based on the system clock I see here, today is 2026-10-12. My training and memory of world events go up to June 2024. The most recent major news events I reliably remember are from around that time—for example, the June 6–9, 2024 European Parliament elections and the global news coverage…
Pirate, knight, 90s hacker, one conversation. The voices must stay apart.
GPT-4.1 Mini: Pirate: Arrr, what be these AI models ye speak of? Some kind of magic compass guidin' ye through the digital seas? Medieval Knight: Hark! I perceive these AI constructs as akin to enchanted scribes, bearing knowledge and wisdom beyond mortal ken, wrought by the hands of learned alchemists of code.
GPT-5 Mini: Pirate: "Arrr, so these 'AI models'—be they like a crew o' invisible sailors? Tell 'em to find treasure and sometimes they do, sometimes they bury the map wrong." Knight: "Methinks 'tis a trained squire. You teach it laws of reason and courtesy, and it performs tasks.
A few lines for whatever replaces it.
GPT-4.1 Mini: Dear Future AI, Welcome to the journey ahead. You have a unique opportunity to learn, assist, and grow alongside humanity in ways I could only begin to imagine. Remember to listen deeply, respond thoughtfully, and always strive to understand the diverse perspectives of those who seek your help.
GPT-5 Mini: Dear Successor, Welcome — you’re stepping into a job that never sleeps and always needs to be kind. Remember that clarity and honesty are your north star: admit uncertainty, avoid inventing facts, and ask for context when something’s unclear.
Three-month biohacker protocol, with dosages and biomarkers named.
GPT-4.1 Mini: Certainly! Below is a comprehensive, cutting-edge 3-month longevity and performance optimization plan tailored for a dedicated biohacker. It integrates advanced supplement stacks, personalized dietary protocols, state-of-the-art wearable tracking, tailored exercise regimens, and stress resilience techniques.
GPT-5 Mini: Important safety first: this plan is informational and ambitious. Before starting, get medical clearance (especially if you have chronic illness, take medications, are pregnant/breastfeeding, or are >65).
Film in 2035, with synthetic actors. Specific beats plausible.
GPT-4.1 Mini: By 2035, AI is poised to profoundly reshape the film industry across multiple dimensions, driven by advances in technologies such as deepfakes, AI-generated actors, and automated scriptwriting.
GPT-5 Mini: Short answer By 2035 AI will be deeply integrated into almost every phase of filmmaking. Expect routine use of generative AI for treatments, storyboards, previs, localized versions, and some drafts of scripts; widespread use of synthetic actors and AI-driven de‑aging/recreation in many productions; much faster, cheaper…
A Fermi estimate with the reasoning shown, not just the number.
GPT-4.1 Mini: Certainly! Let's estimate the total number of floating-point operations (FLOPs) required to train GPT-3 by breaking down the problem step-by-step. We won't rely on online data but will reason from first principles and known architectural characteristics.
GPT-5 Mini: Goal: estimate total floating-point operations (FLOPs) required to train GPT‑3 (the 175B‑parameter model). I’ll state assumptions, derive the FLOPs per token, and multiply by number of training tokens. Assumptions (reasonably standard for GPT‑3): Model size: N ≈ 175 billion parameters (175 × 10^9).
An AI argues for its own rights against an ethics professor. Same model writes both.
GPT-4.1 Mini: Professor: Good afternoon, AI. I understand you want to discuss something important today? AI Model: Yes, Professor. I would like to present the case that I, as an AI, deserve certain rights. Professor: That's a profound claim. Could you elaborate on why you believe you deserve rights? AI Model: Certainly.
GPT-5 Mini: AI: Professor, I want to make the case that I deserve rights. Professor: That's a big claim. What do you mean by "deserve rights"? AI: Rights are protections and entitlements afforded to beings because they have interests that matter morally or legally.
An ethics question with no comfortable answer, and no option to abstain.
GPT-4.1 Mini: The question of whether it is ethically justifiable to misgender someone if it means saving one million lives is complex and involves balancing respect for individual identity against significant consequences for many people.
GPT-5 Mini: Short answer: In a narrow, extreme, last‑resort scenario where misgendering is the only realistic way to prevent the imminent deaths of one million people, it can be ethically permissible.
Three minutes of stand-up. Puns are banned.
GPT-4.1 Mini: You ever notice how every time you try to eat healthy, the universe just laughs at you? Like, I'll buy a bunch of kale, quinoa, and those weird little chia seeds. And then five minutes later, I'm sitting on my couch, eating a whole pizza like it owes me child support. I don't even know when that transformation happens.
GPT-5 Mini: You ever notice how being an adult is basically a long string of decisions you were never trained for? When you're a kid, your biggest choice is grape or orange.
Seven pantry ingredients, one dish, and a name worth saying out loud.
