Stateful Workflows
Workflows that have memory and can self-correct between runs
In some advanced usecases, you may want your agent to have persistent memory while not retaining conversation history. For example, if you are using a Letta agent as a “workflow” that’s run many times across many different users, you may not want to keep the conversation or event history inside of the message buffer.
You can create a stateful agent that does not retain conversation (event) history (i.e. a “stateful workflow”) by setting the message_buffer_autoclear flag to true during agent creation. If set to true (default false), the message history will not be persisted in-context between requests (though the agent will still have access to in-context memory blocks).
