Any reason to only allow loading sessions from CSV and JSON files vs an in memory list?

[jeanmaried]

I store my messages in firebase and am wondering if there is a clean way to create a session without having a .json or .csv file in my file system?

I thought I would try something like this:

chat_messages = []

for message in fb_messages:
        chat_message = ChatMessage(
            role=message['role'], content=message['content'])
        chat_messages.append(chat_message)
        
ai.default_session.messages = chat_messages

ai("Hey there")

This stores the messages but when I call ai I get an error:

AttributeError: 'dict' object has no attribute 'model_dump'

This feels like a common enough use case that the solution could be abstracted into this library. I'm curious if there is either a reason for using files over in memory or if there is a way to upload an in memory list that I am missing?
