GPTbot

GPTbot is a simple bot that uses different APIs to generate responses to messages in a Matrix room.

It is called GPTbot because it was originally intended to only use GPT-3 to generate responses. However, it supports other services/APIs, and I will probably add more in the future, so the name is a bit misleading.

Features

• AI-generated responses to messages in a Matrix room (chatbot)
  • Currently supports OpenAI (tested with gpt-3.5-turbo and gpt-4)
• AI-generated pictures via the !gptbot imagine command
  • Currently supports OpenAI (DALL-E-2/DALL-E-3)
• Mathematical calculations via the !gptbot calculate command
  • Currently supports WolframAlpha
• Voice input and output
  • Currently supports OpenAI (TTS and Whisper)
  • Beta feature, see dedicated section for details
• Automatic classification of messages (for imagine, calculate, etc.)
  • Beta feature, see Usage section for details
• Really useful commands like !gptbot help and !gptbot coin
• sqlite3 database to store room settings

Planned features

• End-to-end encryption support (partly implemented, but not yet working)

Installation

To run the bot, you will need Python 3.10 or newer.

The bot has been tested with Python 3.11 on Arch, but should work with any current version, and should not require any special dependencies or operating system features.

Production

The easiest way to install the bot is to use pip to install it directly from its Git repository:

# If desired, activate a venv first

python -m venv venv
. venv/bin/activate

# Install the bot

pip install git+https://kumig.it/kumitterer/matrix-gptbot.git

This will install the bot from the main branch and all required dependencies. A release to PyPI is planned, but not yet available.

Development

Clone the repository and install the requirements to a virtual environment.

# Clone the repository

git clone https://kumig.it/kumitterer/matrix-gptbot.git
cd matrix-gptbot

# If desired, activate a venv first

python -m venv venv
. venv/bin/activate

# Install the bot in editable mode

pip install -e .[dev]

# Go to the bot directory and start working

cd src/gptbot

Of course, you can also fork the repository on GitHub and work on your own copy.

Configuration

The bot requires a configuration file to be present in the working directory. Copy the provided config.dist.ini to config.ini and edit it to your needs.

Running

The bot can be run with python -m gptbot. If required, activate a venv first.

You may want to run the bot in a screen or tmux session, or use a process manager like systemd. The repository contains a sample systemd service file (gptbot.service) that you can use as a starting point. You will need to adjust the paths in the file to match your setup, then copy it to /etc/systemd/system/gptbot.service. You can then start the bot with systemctl start gptbot and enable it to start automatically on boot with systemctl enable gptbot.

Usage

Once it is running, just invite the bot to a room and it will start responding to messages. If you want to create a new room, you can use the !gptbot newroom command at any time, which will cause the bot to create a new room and invite you to it. You may also specify a room name, e.g. !gptbot newroom My new room.

Reply generation

Note that the bot will respond to all messages in the room by default. If you don't want this, for example because you want to use the bot in a room with other people, you can use the !gptbot roomsettings command to change the settings for the current room. For example, you can disable response generation with !gptbot roomsettings always_reply false.

With this setting, the bot will only be triggered if a message begins with !gptbot chat. For example, !gptbot chat Hello, how are you? will cause the bot to generate a response to the message Hello, how are you?. The bot will still get previous messages in the room as context for generating the response.

Commands

There are a few commands that you can use to interact with the bot. For example, if you want to generate an image from a text prompt, you can use the !gptbot imagine command. For example, !gptbot imagine a cat will cause the bot to generate an image of a cat.

To learn more about the available commands, !gptbot help will print a list of available commands.

Automatic classification

As a beta feature, the bot can automatically classify messages and use the appropriate API to generate a response. For example, if you send a message like "Draw me a picture of a cat", the bot will automatically use the imagine command to generate an image of a cat.

This feature is disabled by default. To enable it, use the !gptbot roomsettings command to change the settings for the current room. !gptbot roomsettings classification true will enable automatic classification, and !gptbot roomsettings classification false will disable it again.

Note that this feature is still in beta and may not work as expected. You can always use the commands manually if the automatic classification doesn't work for you (including !gptbot chat for a regular chat message).

Also note that this feature conflicts with the always_reply false setting - or rather, it doesn't make sense then because you already have to explicitly specify the command to use.

Voice input and output

The bot supports voice input and output, but it is disabled by default. To enable it, use the !gptbot roomsettings command to change the settings for the current room. !gptbot roomsettings stt true will enable voice input, and !gptbot roomsettings tts true will enable voice output. Note that this may be a little unreliable at the moment, especially voice input.

Troubleshooting

Help, the bot is not responding!

First of all, make sure that the bot is actually running. (Okay, that's not really troubleshooting, but it's a good start.)

If the bot is running, check the logs. The first few lines should contain "Starting bot...", "Syncing..." and "Bot started". If you don't see these lines, something went wrong during startup. Fortunately, the logs should contain more information about what went wrong.

If you need help figuring out what went wrong, feel free to open an issue.

Help, the bot is flooding the room with responses!

The bot will respond to all messages in the room, with two exceptions:

• If you turn off response generation for the room, the bot will only respond to messages that begin with !gptbot <command>.
• Messages sent by the bot itself will not trigger a response.

There is a good chance that you are seeing the bot responding to its own messages. First, stop the bot, or it will keep responding to its own messages, consuming tokens.

Check that the UserID provided in the config file matches the UserID of the bot. If it doesn't, change the config file and restart the bot. Note that the UserID is optional, so you can also remove it from the config file altogether and the bot will try to figure out its own User ID.

If the User ID is correct or not set, something else is going on. In this case, please check the logs and open an issue if you can't figure out what's going on.
