A curated field guide to the transformer brain
It collects the scattered tools and papers trying to make large language models less opaque.

What it does
This repository is a curated awesome-list that catalogs resources for understanding large language model internals. It links out to open-source tools like TransformerLens, Rome, and ecco, plus academic papers covering sparse autoencoders, causal tracing, and attention-head analysis. The list also includes articles and community groups, serving as a centralized index rather than a runnable project.
The interesting bit The collection treats LLM interpretability as a cross between archaeology and neuroscience, gathering everything from interactive neuron viewers to papers on how GPT-2 computes “greater-than.” It captures a field that is still largely descriptive—mapping what happens inside weights and activations before anyone can reliably fix it.
Key highlights
- Surfaces practical debugging and visualization tools (
LIT,Phoenix,Comgra) alongside mechanistic interpretability libraries (TransformerLens,Inseq). - Paper coverage ranges from foundational sparse probing to recent work on “successor heads,” social bias neurons, and automated circuit discovery.
- Includes oddball experiments like
SpellGPTprobing token spelling and the Othello world-representation paper, reflecting the field’s current breadth. - Organized into four clean buckets: Tools, Papers, Articles, and Groups.
Caveats
- Descriptions are minimal one-liners, so you will need to follow the links to judge actual utility or maturity.
- A few entries, such as
Floom(an AI gateway) andVanna(SQL-generation RAG), have descriptions that do not obviously connect to interpretability. - The list is comprehensive but flat; there is no ranking, tagging, or commentary to help you prioritize.
Verdict Bookmark this if you are researching or building in mechanistic interpretability and need a broad, periodically updated map of the tooling and literature. If you want a single framework or a guided tutorial, look elsewhere—this is strictly a table of contents.
