Why HN links it

HN readers link François Chollet's Substack posts on how LLMs work, including prompt engineering and LLMs as program databases. Commenters cite them to explain how models handle unfamiliar words.

Summarised by Claude from a sample of 5 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

Ideas on AI, technology, and society. Mostly ephemeral, but carries a small chance of starting a fire.

What Hacker News says?

  1. Actually it's way easier to search for the information in an LLM compared to an 8 tb harddisk. The search is vague, and the result is nondeterministic, but in a lot of cases it's still the better method. https://fchollet.substack.com/i/137628402/llms-as-program-da... I like the way this article puts it. "LLM is a continuous, interpolative kind of database"

    I would read Francois Chollet's explanation of this. It's very good: https://fchollet.substack.com/p/how-i-think-about-llm-prompt... For words that are not in the model's vocabulary, like 'fluftable', the model uses a subword tokenization strategy. It breaks down the word into smaller known subunits (subwords or characters) and represents each subunit with its own vector. By understanding the context in which 'fluft…

  7. The original article [0] is from 2023 and was already posted on HN multiple times. Anyway, while there's something interesting in this mental model, I find this attitude below and particularly the word "rather" to be overly reductive, seeing how you could argue that intelligence in general consists of searching in an abstract database of Platonic ideas. > Viewing LLMs as vector program databases rather than intellig…

  9. > We are tens of months into what looks like the AI age. The modern AI era started in 2017 with the "Attention Is All You Need" paper ( https://arxiv.org/abs/1706.03762 ). ChatGPT is a popular manifestation of something that has been making huge and significant progress (image recognition, language translation, image generation, etc.) since then. This blog post has helped me the most in trying to understand what LLM…
