You can see the full list of available commands when you enter / into the message box.
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.
Install MemGPT:
pip install pymemgptAdd 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 runThe run command supports the following optional flags (if set, will override config defaults):
--agent: (str) Name of agent to create or to resume chatting with.--human: (str) Name of the human to run the agent with.--persona: (str) Name of agent persona to use.--model: (str) LLM model to run [gpt-4, gpt-3.5].--preset: (str) MemGPT preset to run agent with.--data_source: (str) Name of data source (loaded withmemgpt load) to connect to agent.--first: (str) Allow user to sent the first message.--debug: (bool) Show debug logs (default=False)--no_verify: (bool) Bypass message verification (default=False)--yes/-y: (bool) Skip confirmation prompt and use defaults (default=False)
You can run the following commands in the MemGPT CLI prompt:
/exit: Exit the CLI/save: Save a checkpoint of the current agent/conversation state/dump: View the current message log (see the contents of main context)/memory: Print the current contents of agent memory/pop: Undo the last message in the conversation/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>.
You can add new human or persona definitions either by providing a file (using the -f flag) or text (using the --text flag).
# add a human
memgpt add human [-f <FILENAME>] [--text <TEXT>]
# add a persona
memgpt add persona [-f <FILENAME>] [--text <TEXT>]
You can view available persona and human files with the following command:
memgpt list [human/persona]
MemGPT supports pre-loading data into archival memory, so your agent can reference loaded data in your conversations with an agent by specifying the data source with the flag memgpt run --data-source <NAME>.
We currently support loading from a directory and database dumps. We highly encourage contributions for new data sources, which can be added as a new CLI data load command.
Loading from a directory:
# loading a directory
memgpt load directory --name <NAME> \
[--input-dir <DIRECTORY>] [--input-files <FILE1> <FILE2>...] [--recursive]
Loading from a database dump:
memgpt load database --name <NAME> \
--query <QUERY> \ # Query to run on database to get data
--dump-path <PATH> \ # Path to dump file
--scheme <SCHEME> \ # Database scheme
--host <HOST> \ # Database host
--port <PORT> \ # Database port
--user <USER> \ # Database user
--password <PASSWORD> \ # Database password
--dbname <DB_NAME> # Database nameTo encourage your agent to reference its archival memory, we recommend adding phrases like "search your archival memory..." for the best results.
You can view loaded data source with:
memgpt list sources
To use MemGPT with Azure, expore the following variables and then re-run memgpt configure:
# see https://github.com/openai/openai-python#microsoft-azure-endpoints
export AZURE_OPENAI_KEY = ...
export AZURE_OPENAI_ENDPOINT = ...
export AZURE_OPENAI_VERSION = ...
# set the below if you are using deployment ids
export AZURE_OPENAI_DEPLOYMENT = ...
export AZURE_OPENAI_EMBEDDINGS_DEPLOYMENT = ...Note: your Azure endpoint must support functions or you will get an error. See cpacker#91 for more information.
To use custom endpoints, run export OPENAI_API_BASE=<MY_CUSTOM_URL> and then re-run memgpt configure to set the custom endpoint as the default endpoint.
Debugging command not found
If you get command not found (Linux/MacOS), or a CommandNotFoundException (Windows), the directory where pip installs scripts is not in your PATH. You can either add that directory to your path (pip show pip | grep Scripts) or instead just run:
python -m memgptBuilding from source
Clone this repo: git clone https://github.com/cpacker/MemGPT.git
Using poetry:
- Install poetry:
pip install poetry - Run
poetry install - Run
poetry run memgpt
Using pip:
- Run
pip install -e . - Run
python3 main.py
If you're using Azure OpenAI, set these variables instead:
# see https://github.com/openai/openai-python#microsoft-azure-endpoints
export AZURE_OPENAI_KEY = ...
export AZURE_OPENAI_ENDPOINT = ...
export AZURE_OPENAI_VERSION = ...
# set the below if you are using deployment ids
export AZURE_OPENAI_DEPLOYMENT = ...
export AZURE_OPENAI_EMBEDDINGS_DEPLOYMENT = ...
# then use the --use_azure_openai flag
memgpt --use_azure_openaiTo create a new starter user or starter persona (that MemGPT gets initialized with), create a new .txt file in ~/.memgpt/humans or ~/.memgpt/personas, then use the --persona or --human flag when running main.py. For example:
# assuming you created a new file ~/.memgpt/humans/me.txt
memgpt
# Select me.txt during configuration process-- OR --
# assuming you created a new file ~/.memgpt/humans/me.txt
memgpt --human me.txtYou can also specify any of the starter users in /memgpt/humans/examples or any of the starter personas in /memgpt/personas/examples.
You can run MemGPT with GPT-3.5 as the LLM instead of GPT-4:
memgpt
# Select gpt-3.5 during configuration process-- OR --
memgpt --model gpt-3.5-turboNote that this is experimental gpt-3.5-turbo support. It's quite buggy compared to gpt-4, but it should be runnable.
Please report any bugs you encounter regarding MemGPT running on GPT-3.5 to cpacker#59.
You can run MemGPT with local LLMs too. See instructions here and report any bugs/improvements here cpacker#67.
--first
allows you to send the first message in the chat (by default, MemGPT will send the first message)
--debug
enables debugging output
Configure via legacy flags
--model

These are the commands for the CLI, not the Discord bot! The Discord bot has separate commands you can see in Discord by typing /.
While using MemGPT via the CLI (not Discord!) you can run various commands:
//
toggle multiline input mode
/exit
exit the CLI
/save
save a checkpoint of the current agent/conversation state
/load
load a saved checkpoint
/dump
view the current message log (see the contents of main context)
/memory
print the current contents of agent memory
/pop
undo the last message in the conversation
/heartbeat
send a heartbeat system message to the agent
/memorywarning
send a memory warning system message to the agent
MemGPT's archival memory let's you load your database and talk to it! To motivate this use-case, we have included a toy example.
Consider the test.db already included in the repository.
| id | name | age |
|---|---|---|
| 1 | Alice | 30 |
| 2 | Bob | 25 |
| 3 | Charlie | 35 |
To talk to this database, run:
memgpt --archival_storage_sqldb=memgpt/personas/examples/sqldb/test.dbAnd then you can input the path to your database, and your query.
Please enter the path to the database. test.db
...
Enter your message: How old is Bob?
...
🤖 Bob is 25 years old.MemGPT enables you to chat with your data locally -- this example gives the workflow for loading documents into MemGPT's archival memory.
To run our example where you can search over the SEC 10-K filings of Uber, Lyft, and Airbnb,
-
Download the .txt files from Hugging Face and place them in
memgpt/personas/examples/preload_archival. -
In the root
MemGPTdirectory, runmemgpt --archival_storage_files="memgpt/personas/examples/preload_archival/*.txt" --persona=memgpt_doc --human=basic
If you would like to load your own local files into MemGPT's archival memory, run the command above but replace --archival_storage_files="memgpt/personas/examples/preload_archival/*.txt" with your own file glob expression (enclosed in quotes).
In the root MemGPT directory, run
memgpt main.py --archival_storage_files_compute_embeddings="<GLOB_PATTERN>" --persona=memgpt_doc --human=basicThis will generate embeddings, stick them into a FAISS index, and write the index to a directory, and then output:
To avoid computing embeddings next time, replace --archival_storage_files_compute_embeddings=<GLOB_PATTERN> with
--archival_storage_faiss_path=<DIRECTORY_WITH_EMBEDDINGS> (if your files haven't changed).
If you want to reuse these embeddings, run
memgpt --archival_storage_faiss_path="<DIRECTORY_WITH_EMBEDDINGS>" --persona=memgpt_doc --human=basicMemGPT also enables you to chat with docs -- try running this example to talk to the LlamaIndex API docs!
-
a. Download LlamaIndex API docs and FAISS index from Hugging Face.
# Make sure you have git-lfs installed (https://git-lfs.com) git lfs install git clone https://huggingface.co/datasets/MemGPT/llamaindex-api-docs mv llamaindex-api-docs-- OR --
b. Build the index:
- Build
llama_indexAPI docs withmake text. Instructions here. Copy over the generated_build/textfolder tomemgpt/personas/docqa. - Generate embeddings and FAISS index.
cd memgpt/personas/docqa python3 scrape_docs.py python3 generate_embeddings_for_docs.py all_docs.jsonl python3 build_index.py --embedding_files all_docs.embeddings.jsonl --output_index_file all_docs.index
- Build
-
In the root
MemGPTdirectory, runmemgpt --archival_storage_faiss_path=<ARCHIVAL_STORAGE_FAISS_PATH> --persona=memgpt_doc --human=basic
where
ARCHIVAL_STORAGE_FAISS_PATHis the directory whereall_docs.jsonlandall_docs.indexare located. If you downloaded from Hugging Face, it will bememgpt/personas/docqa/llamaindex-api-docs. If you built the index yourself, it will bememgpt/personas/docqa.
