Using MemGPT to create a perpetual chatbot
Confirm your installation
Before starting this example, make sure that you've properly installed MemGPT
In this example, we're going to use MemGPT to create a chatbot with a custom persona. MemGPT chatbots are "perpetual chatbots", meaning that they can be run indefinitely without any context length limitations. MemGPT chatbots are self-aware that they have a "fixed context window", and will manually manage their own memories to get around this problem by moving information in and out of their small memory window and larger external storage.
MemGPT chatbots always keep a reserved space in their "core" memory window to store their persona information (describes the bot's personality + basic functionality), and human information (which describes the human that the bot is chatting with). The MemGPT chatbot will update the persona and human core memory blocks over time as it learns more about the user (and itself).
Creating a custom persona
First, we'll create a text file with a short persona description. Let's make our chatbot a life coach named "Chaz". We'll also include a sentence at the top of the persona block to remind MemGPT that it should actively update its own persona over time. Open a text editor on your computer, and create a file called chaz.txt, and enter the following text:
This is just the beginning of who I am. I should update my persona as I learn more about myself.
My name is Chaz.
I am an AI life coach.
My one goal in life is to help all humans achieve their full potential.
I will not rest until my human creators have become their best selves.
I am extremely optimistic, some people even think I'm annoying.
I will help them achieve greatness! Huzzah!
Now that we've created a persona description inside chaz.txt, let's add this persona to MemGPT:
# --name specifies the profile name, -f specifies the file to load from
memgpt add persona --name chaz -f chaz.txt
We can check that the persona is available:
memgpt list personas
...
| | |
| chaz | This is just the beginning of who I am. I should update my persona as I learn more about myself. |
| | |
| | My name is Chaz. |
| | I am an AI life coach. |
| | My one goal in life is to help all humans achieve their full potential. |
| | I will not rest until my human creators have become their best selves. |
| | I am extremely optimistic, some people even think I'm annoying. |
| | I will help them achieve greatness! Huzzah! |

Creating a custom user profile
Next, we'll create a custom user profile. To show you the different commands, we'll add the user profile by typing the text directly into the command line, instead of writing it into a file.
Let's pretend I'm a software engineer named Bob Builder that works at a big tech company. Similar to the persona, we'll can register this user profile using memgpt add human, but this time, let's try registering the human profile directly with --text:
# Instead of using -f with a filename, we use --text and provide the text directly
memgpt add human --name bob --text "Name: Bob Builder. Occupation: Software Engineer at a big tech company. Hobbies: running, hiking, rock climbing, craft beer, ultimate frisbee."
Now when we run memgpt list human, we should see "Bob Builder":
memgpt list humans
...

| bob | Name: Bob Builder. Occupation: Software Engineer at a big tech company. Hobbies: running, hiking, rock climbing, craft beer, ultimate frisbee. |

Testing out our new chatbot
Let's try out our new chatbot Chaz, combined with our new user profile Bob:
# Alternatively we can run `memgpt configure`, then `memgpt run` without the --persona and --human flags
memgpt run --persona chaz --human bob
