Vector Databases, Deep Indexing & Token Economics: The Complete Story (phase 3)
1+ week, 1+ day ago (1673+ words) From "we have vectors" to "this actually scales, and doesn't bankrupt us." 👦 Nephew: Uncle, Phase 2 is done. I understand tokenization, embeddings, cosine similarity. But two things are bugging me. First — where do these vectors actually live, physically? Second — when we…...
How Forcing 1024-Dim Embeddings Cut Our Pinecone Bill by ~33%
2+ week, 6+ day ago (354+ words) If you've built a RAG pipeline before, you know the pattern: hook up an embedding model, dump vectors into Pinecone, and forget about it until the invoice shows up. That invoice is where most people first realize embedding dimensionality isn't…...
