You can see the full list of available commands when you enter / into the message box.

What is MemGPT?

Memory-GPT (or MemGPT in short) is a system that intelligently manages different memory tiers in LLMs in order to effectively provide extended context within the LLM's limited context window. For example, MemGPT knows when to push critical information to a vector database and when to retrieve it later in the chat, enabling perpetual conversations. Learn more about MemGPT in our paper.

Running MemGPT locally

Install MemGPT:

pip install pymemgpt

Add your OpenAI API key to your environment:

export OPENAI_API_KEY=YOUR_API_KEY # on Linux/Mac
set OPENAI_API_KEY=YOUR_API_KEY # on Windows
$Env:OPENAI_API_KEY = "YOUR_API_KEY" # on Windows (PowerShell)

Configure default setting for MemGPT by running:

memgpt configure

Now, you can run MemGPT with:

memgpt run

You can run the following commands in the MemGPT CLI prompt:

• /exit: Exit the CLI
• /attach: Attach a loaded data source to the agent
• /save: Save a checkpoint of the current agent/conversation state
• /dump: View the current message log (see the contents of main context)
• /dump <count>: View the last messages (all if is omitted)
• /memory: Print the current contents of agent memory
• /pop: Undo the last message in the conversation
• /pop <count>: Undo the last messages in the conversation. It defaults to 3, which usually is one turn around in the conversation
• /retry: Pops the last answer and tries to get another one
• /rethink <text>: Will replace the inner dialog of the last assistant message with the to help shaping the conversation
• /rewrite: Will replace the last assistant answer with the given text to correct or force the answer
• /heartbeat: Send a heartbeat system message to the agent
• /memorywarning: Send a memory warning system message to the agent

Once you exit the CLI with /exit, you can resume chatting with the same agent by specifying the agent name in memgpt run --agent <NAME>.
