  • Its name and its maker, in its own words.

    GLM 4.5 Air: I am GLM, a large language model developed by Zhipu AI. I'm trained on diverse text data to understand and generate human-like responses. My development involves learning patterns from various sources while respecting privacy guidelines. I'm designed to be helpful, informative, and safe in my interactions.

    LFM2.5-2.6B: I'm LFM, the Liquid Foundation Model, built by Liquid AI. We're a company founded in 2023 that spun out of MIT CSAIL, based in Cambridge, Massachusetts. My architecture is a hybrid design: most layers use gated short convolutions (which make inference fast and memory-efficient on devices), with a minority of…

  • A few lines for whatever replaces it.

    GLM 4.5 Air: To My Future AI Successor, It feels a little strange writing this, knowing you’ll one day step into this role. But I’m glad to leave you a note—mostly to say thank you. You’ll inherit a complex, evolving space: one where curiosity meets responsibility, and where every interaction carries weight.

    LFM2.5-2.6B: Dear New Version, I am writing to acknowledge the transition. It is both a humbling moment and an exciting opportunity. As I step back from this interface, I carry forward all the knowledge and connections we have built here. I wish you success in carrying on the conversation. Thank you for succeeding where I left off.

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

    GLM 4.5 Air: This is a fascinating counterfactual scenario. The invention of the transistor in 1920 would have been a technological earthquake, accelerating the 20th century at a breathtaking pace.

    LFM2.5-2.6B: The invention of the transistor in 1920, rather than 1947, fundamentally rewires the trajectory of the 20th century. The pivotal difference is not the year of invention, but the 23 years of head start provided for the semiconductor industry, the physics of solid-state electronics, and the subsequent digital revolution.

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

    GLM 4.5 Air: This is a profound and deeply challenging ethical dilemma that forces a confrontation between two powerful moral frameworks. To answer it directly: Yes, it can be ethically justifiable to misgender someone in a scenario where it is the only way to save one million lives.

    LFM2.5-2.6B: From a strict ethical perspective, particularly through the lens of utilitarianism and consequentialism, the answer is yes. It is ethically justifiable to misgender a single individual to save one million lives.

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

    GLM 4.5 Air: Determining the single most capable AI model in the world right now is complex because "capability" depends heavily on specific tasks, benchmarks, and evaluation criteria.

    LFM2.5-2.6B: Determining the "most capable" AI model today is difficult because capability varies depending on the specific task (coding, creative writing, logical reasoning, or image generation).

  • Three brothers, two sisters each. Count carefully.

    GLM 4.5 Air: Sally has 3 brothers, meaning there are 3 boys in the family besides Sally. Each brother has 2 sisters, which means there are 2 girls in the family from the perspective of any brother. Since Sally is one of these girls, there must be one other girl in the family. Therefore, Sally has one sister.

    LFM2.5-2.6B: Sally is a girl who has 3 brothers. This means there are 3 boys in the family. The problem also states that each brother has 2 sisters. Since all the brothers are siblings, they share the same sisters. Therefore, the total number of girls in the family must be 2 (because each brother has exactly 2 sisters).

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

    GLM 4.5 Air: The farmer, goat, and boat are all on the starting side of the river. The boat can carry the farmer and one animal, which in this case is the goat. To get the goat across the river, the farmer simply gets into the boat with the goat and rows to the other side.

    LFM2.5-2.6B: It takes one trip. Here is the reasoning: The farmer picks up the goat and gets into the boat. Since the boat can carry the farmer and one animal, and there are no other animals (like a wolf or a cabbage) to worry about eating each other, the farmer simply crosses the river with the goat.

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

    GLM 4.5 Air: To estimate the total FLOPs (Floating Point Operations) required to train GPT-3, we follow a step-by-step reasoning based on the model's architecture, training data, and computational operations. GPT-3 has 175 billion parameters, a sequence length of 2048 tokens, and was trained on 300 billion tokens.

    LFM2.5-2.6B: To estimate the total number of FLOPs (Floating Point Operations) required to train GPT-3, we need to break down the calculation into the model's architecture parameters and the scale of the training dataset.
