Cohere Citations Chat Engine Pack

Cohere Citations Chat Engine Pack

Creates and runs a custom VectorStoreIndexWithCitationsChat -- which provides the chat engine with documents/citation mode.
See the documentation here and here.

CLI Usage

You can download llamapacks directly using llamaindex-cli, which comes installed with the llama-index python package:
