Vector Databases: from Embeddings to Applications
If you're going to use a vector DB (and in 2026 most AI engineers will), this is the right 90 minutes to spend. Covers embeddings, ANN algorithms, sparse vs dense, hybrid search, and a head-to-head of Pinecone, Weaviate, Chroma and pgvector. Free, vendor-agnostic enough despite the Weaviate teaching credit. Take before you commit to a vector DB.

Pinecone Learn
Pinecone Learn (vector DB + RAG)
Pinecone's free learn portal. Despite being vendor-published, the content is genuinely vendor-agnostic for the first 60% (embedding theory, ANN basics, hybrid search) and only becomes Pinecone-specific in deployment chapters. James Briggs is one of the best practical-RAG explainers in the field. Free, continuously updated, with code examples that run.
