Get OpenAI API To Always Cite Source From Pinecone

Hello,

I typically use the OpenAI API along with Pinecone instead of the Assistants API. Querying Pinecone returns source and associated text which I pass to OpenAI as a text string like:

"
source: abc.com

text: this is a test
"

As a part of the prompt along with a message to always cite the source. It doesn’t always do this though. How can I get the response to always cite the source it uses?
