AI Tutor vector DB — public docs-only bundle
Prebuilt retrieval artifacts for the Towards AI tutor chatbot:
a ChromaDB collection (Cohere embed-v4.0 embeddings), BM25 index and
document dictionary, plus the file-based knowledge base (kb/) the agent
browses at runtime.
This is the public fallback for the private
towardsai-tutors/ai-tutor-vector-db bundle. It contains documentation
sources only (claude_code_docs, deep_agents, langchain, langgraph, llama_index, openai_docs, peft, transformers, trl); the Towards AI course content that ships in
the private bundle is not included. The app downloads this bundle
automatically on first start when no HF_TOKEN (or one without access to the
private dataset) is available.
Derived from the production artifacts by
data/scraping_scripts/build_public_docs_bundle.py — an allowlist filter over
the prod bundle (same embeddings, same tree layout), followed by a leak audit.
Documentation content belongs to its upstream projects and keeps their
respective licenses.
