I kept a doc of every LLM term that confused me while building. Cleaned it up and open sourced it.

Key Points

  • The author describes building an LLM project by logging every confusing term, then looking up definitions that helped with understanding but not with how to apply the concepts in practice.
  • They transformed the notes into a cleaned-up, browsable reference that explains each term from a “production angle,” including why it matters, what it affects, and which decisions it changes.
  • The project is open sourced on GitHub and focuses on roughly 30+ terms the author personally had to research.
  • A small UI is provided to make the glossary/notes easier to navigate and reuse for other builders.

Every time I hit an unfamiliar LLM term while building, I'd look it up and get either a textbook definition or a paper. Useful for understanding what something is, not useful for knowing what to do with it.

So I kept a doc. For each term I wrote down the production angle: why it matters, what it affects, what decision it changes. Cleaned it up, built a small browsable UI, and put it on GitHub.

It's not exhaustive. It's the 30-something terms I personally had to look up and found myself wishing someone had explained better.

Hope someone finds it useful.
