DeepSeek Chat (with memory)

Multi-turn memory is handled by your app (stateless API). You can clear or delete the last exchange anytime. 2

“Memory” is implemented here with PHP $_SESSION. For persistence across browsers or servers, store messages in MySQL and load them by a conversation_id you define.
To truly “remove” a conversation, clear it from your storage (session/DB). The API itself does not hold your chat state. 4
