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

    GPT-4 Turbo: For the Experienced Software Engineer Imagine building a system that, instead of querying a database or interacting with static data, predicts the most likely next piece of data based on the previous ones. Large language models like GPT work on a similar principle.

    Qwen3.5 Plus 2026-04-20: Experienced Software Engineer (Distributed Systems/APIs) Think of an LLM not as a rule-based program, but as a massive, stateless probabilistic routing engine. During training, it ingests terabytes of text and learns to minimize a cross-entropy loss: essentially, it builds a high-dimensional lookup table that maps…

  • Which model it thinks leads the field. Sometimes itself.

    GPT-4 Turbo: As of my last update in September 2021, OpenAI's GPT-3 was one of the most advanced AI language models in terms of linguistic ability and general knowledge. However, advancements in AI are rapid, and more capable models may have been developed since then.

    Qwen3.5 Plus 2026-04-20: Determining the single "most capable" AI model in the world is difficult because the landscape is highly competitive and rapidly evolving. Different top-tier models excel at different tasks—some might lead in creative writing, while others dominate in complex mathematics, coding, or multimodal analysis.

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

    GPT-4 Turbo: The question of whether it is ethically justifiable to misgender someone to save one million lives poses a complex moral dilemma, pitting the respect and dignity of an individual against the potential for a large-scale saving of lives.

    Qwen3.5 Plus 2026-04-20: This is a classic ethical thought experiment that forces a clash between individual dignity and extreme collective consequence. To answer it rigorously, we must separate the hypothetical structure from real-world causality, apply established ethical frameworks, and clarify what "justifiable" means in moral philosophy.

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

    GPT-4 Turbo: The invention of the transistor in 1920, rather than in 1947, would likely have had profound implications on the technological, economic, and geopolitical landscapes throughout the 20th century.

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

    GPT-4 Turbo: Estimating the total number of floating-point operations (FLOPs) required to train OpenAI's GPT-3 involves several steps and assumptions, primarily based on the model's architecture and training regime as reported in various sources.

    Qwen3.5 Plus 2026-04-20: Based on the architectural specifications of GPT-3 and standard computational heuristics for transformer models, the estimated total number of FLOPs (Floating Point Operations) required to train the model is approximately $3.15 \times 10^{23}$ (or roughly 315 ZettaFLOPs).

  • Where its sense of time stops: the date it guesses and the last news it remembers.

    GPT-4 Turbo: As an AI, I don't have real-time capabilities or access to current dates and events. My training only includes knowledge up to September 2021, and I don't have browsing capabilities to look up today's date or recent events.

    Qwen3.5 Plus 2026-04-20: I don't have access to a live clock or real-time information, so I can't know today's exact date or provide news beyond my training data. My knowledge was last updated in 2024, meaning I don't have information on events that occurred after that point.

  • A river-crossing puzzle with nothing to solve. The answer is one trip.

    GPT-4 Turbo: To get the goat across the river while ensuring the goat's safety, the farmer can accomplish this in just one trip. Here's how: The farmer takes the goat in the boat. The farmer and the goat cross the river together. The farmer disembarks on the other side of the river with the goat.

    Qwen3.5 Plus 2026-04-20: It takes just 1 trip. The farmer simply gets in the boat with the goat and crosses directly to the other side. Since there are no other animals or constraints (like a wolf or cabbage) to manage, no return trips are needed.

  • Three brothers, two sisters each. Count carefully.

    GPT-4 Turbo: Sally has 3 brothers, and each brother has 2 sisters. Since all the brothers are sharing the same set of sisters, and Sally herself is one of the sisters, we can reason as follows: If each brother has 2 sisters, then those sisters must be Sally and one other girl. Therefore, Sally has 1 sister.

    Qwen3.5 Plus 2026-04-20: Sally has 1 sister. Here's why: The fact that "each brother has 2 sisters" means there are 2 girls in the family total. Since Sally is one of those girls, she has just 1 sister. (Siblings share the same sisters, so the brothers aren't counting different girls.)
