Key Features

  • LLMs Integration: Use Databricks-hosted large language models (LLMs) like Llama and Mixtral through ChatDatabricks.
  • Vector Search: Store and query vector representations using DatabricksVectorSearch.
  • Embeddings: Generate embeddings with DatabricksEmbeddings.
  • Genie: Use Genie in Langchain.

Getting Started

llm = ChatDatabricks(endpoint="databricks-meta-llama-3-1-70b-instruct")
