Chroma

Chroma is the open-source embedding database. Chroma makes it easy to build LLM apps by making knowledge, facts, and skills pluggable for LLMs.

Discord GitHub stars



Chroma gives you the tools to:

  • store embeddings and their metadata
  • embed documents and queries
  • search embeddings

Chroma prioritizes:

  • simplicity and developer productivity
  • analysis on top of search
  • it also happens to be very quick

Chroma consists of a Python client SDK, JavaScript/TypeScript client SDK and a server application. Check out the Colab demo.(yes, it can run in a notebook 😄)
