Storing Conversation State

State

Part of: Build a Chatbot

Your chatbot script works until you close the terminal. Reopen it, say "hi" again, and the bot has forgotten your name, your persona, everything. The Python list that held the history lived in memory, and memory died with the process. The model never had the memory; your program did, and you just let it evaporate. What conversation state is From lesson 1 you know the model is stateless : it keeps nothing between calls. That means the conversation history has to live somewhere outside the model, and the obvious place (a list in a running script) is the most fragile one. Conversation state is the durable copy of that history: where you persist the messages so you can rebuild the exact same list on the next call, even after a restart, a crash, or a switch to a different server. The rule never changes: the app holds the history, not the model. What changes as your chatbot grows up is how durably the app holds it: from a list, to a per-user session store, to a database. How it works Statelessness has a direct consequence: there is no "continue where we left off" button. Every call, you resend the full message list, so every call you must first load that list from wherever you stored it.
