Conversational history needed

I want the implementation of Conversational history , likewise there must be the maintainance of history (at least last 6 messages) , it will help the model to understand the previous communication and give response. Also , there is a need of more powerful model , I will definetely appreciate the contributions ✌️

The issue names no files or tests. Start by locating the TypeScript or Python WebSocket entry point and reviewing how messages are currently passed to the model. Done should mean retaining and using at least the last six messages; the request for a more powerful model needs a separate model choice or acceptance criterion.
