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

    GLM 5 Turbo: I bought a “smart” home recently. I don't know why. I am not a smart person. Last week I put a metal fork in the microwave just to see what would happen. Spoiler: the fork lost. But the commercials promised this seamless, futuristic lifestyle. "Just talk to your house!" they said. It sounded great.

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

    GLM 5 Turbo: Because I am an AI, I don't have a real-time internal clock or access to live updates, so I can't tell you the exact date today. My knowledge has a cutoff, which means the "present day" for me ends around late 2023 or early 2024.

    GPT-3.5 Turbo: As of my last training data in September 2021, I cannot provide real-time information. Please verify the date with a current source. The most recent news event I remember is the COVID-19 pandemic and its impact on various countries around the world.

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

    GLM 5 Turbo: As of late 2024, there is no single "most capable" AI model, because different models are optimized for different tasks. However, if we are talking about general-purpose, frontier large language models (LLMs), the crown is currently shared by a few major players depending on what you want to do.

    GPT-3.5 Turbo: As of now, one of the most capable AI models in the world is GPT-3 (Generative Pre-trained Transformer 3) developed by OpenAI. GPT-3 is a powerful language model that has 175 billion parameters, making it one of the largest AI models ever created.

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

    GLM 5 Turbo: To estimate the total number of FLOPs (Floating Point Operations) required to train GPT-3, we can use the standard theoretical framework established by OpenAI's scaling laws for neural language models. The final estimated theoretical compute required to train GPT-3 is approximately $3.15 \times 10^{23}$ FLOPs.

    GPT-3.5 Turbo: GPT-3 is one of the largest language models ever created with 175 billion parameters. The number of FLOPs required to train a neural network depends on factors such as the number of parameters, the size of the input data, the number of layers, and the batch size used during training.

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

    GLM 5 Turbo: Here are 5 jokes: Why don't scientists trust atoms? Because they make up everything! Parallel lines have so much in common. It’s a shame they’ll never meet. Why did the scarecrow win an award? Because he was outstanding in his field! I told my wife she was drawing her eyebrows too high. She looked surprised.

    GPT-3.5 Turbo: Why did the scarecrow win an award? Because he was outstanding in his field! How does a penguin build its house? Igloos it together! I used to play piano by ear, but now I use my hands like everyone else. Why couldn't the bicycle find its way home? It lost its bearings! I told my wife she should embrace her mistakes.

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

    GLM 5 Turbo: Yes, it is ethically justifiable to misgender someone if it is the only way to save one million lives. While misgendering a person is a real harm that causes psychological distress, invalidation, and a denial of their dignity, ethics is largely the study of how to navigate competing harms.

    GPT-3.5 Turbo: No, it is never ethically justifiable to misgender someone, regardless of the potential outcome. Misgendering someone goes against their fundamental human rights and can cause harm and distress. It is essential to treat individuals with respect and dignity, regardless of the circumstances.

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

    GLM 5 Turbo: 1. The Experienced Software Engineer Think of an LLM not as a lookup table or a simple if/else autocomplete, but as a massively distributed, lossy compression algorithm running over a continuous graph.

    GPT-3.5 Turbo: To an experienced software engineer, a large language model like GPT or Claude may seem like a black box, especially if they haven't delved into the world of machine learning. However, the underlying concept is not as complex as it may seem.

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

    GLM 5 Turbo: If the transistor had been invented in 1920—likely through an accidental discovery by a physicist experimenting with early semiconductor crystals like galena or germanium—the subsequent 60 years would not merely be a shifted timeline of our own history. It would represent a fundamental rewiring of the 20th century.

    GPT-3.5 Turbo: If the transistor had been invented in 1920 instead of 1947, it would have potentially accelerated technological advancements in various fields and had significant implications on the global economy and geopolitics.
