@juspay/neurolink/dist/types/vectorStoreChroma.d.ts

The pipe layer of an AI nervous system: one interface connecting provider neurons to your application, across three inference types — generate, stream and decide. `decide` returns typed, calibrated judgements from a non-generative model (~400ms, ~$0.00002

/**
 * Structural types for the Chroma vector store adapter
 * (`src/lib/rag/stores/chroma.ts`).
 *
 * These mirror the subset of the `chromadb` package's API the adapter
 * calls (`ChromaClient.getOrCreateCollection`, `Collection.upsert/query/
 * delete`). NeuroLink has zero runtime dependency on `chromadb` — callers
 * construct their own client and inject an object satisfying
 * `ChromaClientLike`.
