     The `agent_id` retains memories exclusively based on messages generated by the assistant or those explicitly provided as input to the assistant. Messages outside these criteria are not stored as memory.
 </Note>
 
+#### Long-term memory for both users and agents
+When you provide both `user_id` and `agent_id`, Mem0 will store memories separately for each:
+- User messages are stored under the specified `user_id`
+- Assistant messages are stored under the specified `agent_id`
+
+This allows both the user and agent to maintain their own consistent memory across sessions.
