Sub-Millisecond Context: How Aho-Corasick Automata Replace Embedding Calls
Vector embedding calls are the hidden tax on every RAG pipeline. You pay latency, you pay API cost, you get probabilistic results that vary run to run. There is a class of problem where none of that is acceptable. This post shows how Terraphim replaces embedding calls with Aho-Corasick finite-state automata -- deterministic, auditable, and under one millisecond for 1.4 million patterns.
