Thanks — you're asking whether LiveKit Agents only keep the last 5 messages in memory. No — LiveKit Agents do not automatically limit memory to the last five messages. Each AgentSession starts with an empty chat context, but the full conversation history for that session is preserved and available through

session.history

. Messages added during a user turn via

on_user_turn_completed

are not persisted automatically beyond that turn unless you explicitly save them with

update_chat_ctx

. For long-term or cross-session memory you can integrate external stores (e.g., Letta, LlamaIndex, Mem0). Would you like instructions for reading/writing

session.history

or for integrating an external memory store? Sources: Agents and handoffs | LiveKit docs | Pipeline nodes and hooks | LiveKit docs | External data and RAG | LiveKit docs
