Chroma

Chroma is the open-source vector database engineered for AI: it simplifies the storage and retrieval of vector embeddings for large language models (LLMs).

Chroma functions as the critical memory layer for modern Generative AI applications, specifically powering Retrieval-Augmented Generation (RAG). It stores vector embeddings (numerical representations of unstructured data like text or images) and associated metadata. This architecture enables low-latency, high-accuracy similarity searches using metrics like cosine distance. Developers can deploy it locally or use the managed Chroma Cloud, leveraging Python and JavaScript/TypeScript SDKs for rapid prototyping and production-scale LLM context retrieval.
