Validate activity before betting a new project on korvus. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ## Common questions ### What is the difference between moby and korvus? moby: The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems. korvus: Korvus is a search SDK that unifies the entire RAG pipeline in a single database query.
