From Query to Conversation: GraphQL as an AI Interface Layer
summary
Meta builds an AI layer that discovers and loads subschemas on demand so LLMs can generate real GraphQL operations against thousands of types; it uses an embedding pipeline and vector search index to find relevant root fields, then a dynamic subschema generation tool (replacing manual load_subschema) to produce SDL on the fly. Token cost drops from tens of thousands to hundreds, coverage becomes exhaustive and maintenance zero, but the architecture requires indexing, ranking by traffic, and access controls with a sensitive-mode flag.
