5## Assuming Zep is running locally on default port 8000
6## For cloud service, you would provide api_key and api_url
7## The question of 'is Zep memory free' is answered by self-hosting this.
8memory = ZepMemory(url="http://localhost:8000")
9
10llm = OpenAI(temperature=0)
11conversation = ConversationChain(llm=llm, memory=memory, verbose=True)
12
13conversation.predict(input="Hello, my name is Alex.")
14conversation.predict(input="What is my name?")
