As generation commoditised, retrieval quality became the actual differentiator. That makes this a well-timed name rather than merely a descriptive one. Finder models are a real thing in machine learning: models whose job is retrieval rather than generation, locating the relevant item in a large collection. Retrieval is the unglamorous half of every useful AI system and increasingly the half determining whether it works at all. The name suits a search or retrieval product, a recommendation engine, a vector search company, or a research group.
