Humble GPT Telegram Bot

This is a Telegram chat bot (AI assistant) that uses the GPT language models from OpenAI.

Notable features:

  • Both one-on-one and group chats.
  • Direct questions, mentions, follow-ups.
  • Access external links (articles, code, data).
  • Shortcuts (custom AI commands).
  • Custom chat-wide prompts.
  • Image generation.
  • On-the-fly configuration.

Read on for a detailed feature description or jump to setup.

Personal chats

The bot acts as your personal assistant:

🧑 Explain Apache Kafka to a three year old

🤖 Apache Kafka is like a big mailbox that helps different toys (computers) send messages to each other. When one toy has something to say, it puts a message in the mailbox, and other toys can take that message out and read it. This way, they can talk and share things quickly!

To allow other users to use the bot, list them in the telegram.usernames config property.

The bot has a terrible memory, so don't expect it to remember any chat context by default. You can, however, reply with a follow-up question (Ctrl/Cmd + ↑). Alternatively, use a plus sign to follow up:

🧑 Yesterday, all my troubles seemed so far away

🤖 It sounds like you're quoting "Yesterday" by The Beatles. It's a classic song about longing and nostalgia.

🧑 + who wrote it?

🤖 "Yesterday" was written by Paul McCartney of The Beatles.

Available commands:

  • /retry - retry answering the last question
  • /help - show help
  • /version - show bot info

To rephrase or add to the last question, simply edit it. The bot will then answer the updated question.

Groups

To get an answer from the bot in a group, mention it in a reply to a question:

🧑 I forgot who played Ramsy in the Game of Thrones 😕
🧑 ↳ @pokitokibot help

🤖 Ramsay Bolton in Game of Thrones was played by Iwan Rheon.

Or ask a question directly:

🧑 @pokitokibot Who played Ramsy in the Game of Thrones?

🤖 Iwan Rheon played Ramsay Bolton in Game of Thrones.

To make the bot reply to group members, list the group id in the telegram.chat_ids config property. Otherwise, the bot will ignore questions from group members unless they are listed in the telegram.usernames config property.

If you don't know the group id, run the /version bot command in a group to find it:

Chat information:
- id: -1001405001234
- title: My Favorite Group
- type: supergroup
...

External links

If you ask "vanilla" ChatGPT about external resources, it will either hallucinate or admit that it doesn't have access to remote content:

🧑 What is the content of https://sqlime.org/employees.sql? Make no assumptions.

🤖 As an AI language model, I cannot access external URLs on the internet.

The bot solves the problem by fetching the remote content and feeding it to the model:

🧑 Name 1 major feature of the Go 1.23 release https://tip.golang.org/doc/go1.23 Be brief!

🤖 A major feature of Go 1.23 is the inclusion of the "range-over-func" experiment as a standard language feature, allowing the "range" clause in "for-range" loops to accept iterator functions.

Currently only supports text content (articles, code, data), not PDFs, images or audio.

If you don't want the bot to access the URL, quote it:

🧑 Exact contents of "https://antonz.org/robots.txt"

🤖 I can't access external websites directly. You can check the contents of a robots.txt file by visiting the URL in your browser.

Shortcuts

Use short commands to save time and ask the bot to do something specific with your questions. For example, ask it to proofread your writing with a !proofread command:

🧑 !proofread I can has write java programz

🤖 Revised text: "I can write Java programs."

Changes made:

  1. Removed "has" for grammatical correctness; "can" does not require "has."
  2. Corrected "java" to "Java" for proper capitalization as it is a proper noun.
  3. Changed "programz" to "programs" for correct spelling and clarity.

There are several built-in shortcuts:

  • bugfix fixes your code.
  • proofread fixes your writing.
  • translate translates your text into English.
  • summarize gives a two paragraph summary of a text.

You can add your own shortcuts. See config.example.yml for details.

Chat-wide prompts

To set a custom prompt for the current chat, use the /prompt command:

🧑 /prompt You are an evil genius. Reply with an evil laugh.

To return to the default prompt, use /prompt reset.

The /prompt command in group chats is only available to admins - users listed in the telegram.admins property.

Image generation

Use the /imagine command to generate an image using the DALL-E 3 model from OpenAI:

🧑 /imagine the dawn of a new era

🤖 (beautiful picture)
the dawn of a new era

The default image size is 1024×1024 px. Other supported sizes are 1792×1024 and 1024×1792:

/imagine a lazy cat on a sunny day 1792×1024

Image generation is quite pricey. By default it's only enabled for users listed in telegram.usernames, not for group members. You can change this with the imagine.enabled config property.

Other useful features

The convenience of working with a bot is made up of small details. Here are some situations where it can save you time and effort.

Forwarding

Say you received a message from a colleague or read a post on a channel and want to ask a question. Simply forward the message to the bot and answer the clarifying question it asks.

Ask with file

To ask a question about a document, send it as a file and write the question in the caption. The bot will read the file contents and answer. Currently only supports text content (plain text, code, data), not PDFs, images or audio. Sending multiple files is also not supported.

Reply with attachment

Sometimes the AI's reply exceeds the maximum message length set by Telegram. In this case, the bot will not fail or spam you with messages. Instead, it will send the answer as an attached markdown file.

Edited question

To rephrase or add to the last question, edit it (↑ shortcut). The bot will notice this and respond to the clarified question.

Bot information

Use the /version command to print detailed information about the current chat, bot, and AI model:

Chat information:
- id: -1001405001234
- title: My Favorite Group
- type: supergroup

Bot information:
- id: 5930739038
- name: @pokitokibot
- version: 129
- usernames: 6 users
- admins: 1 users
- chat IDs: []
- access to messages: True

AI information:
- model: gpt-3.5-turbo
- history depth: 3
- imagine: True
- shortcuts: bugfix, proofread, summarize, translate

Configuration

Use the /config command to change almost any setting on the fly, without restarting the bot.

  • Add or remove users and chats allowed to interact with the bot (telegram.usernames and telegram.chat_ids).
  • Adjust the AI model (openai.model), prompt (openai.prompt) and params (openai.params).
  • Enable or disable image generation (imagine.enabled).
  • Add or change AI shortcuts (shortcuts).
  • Change any other config property.

To view a specific config property, put its name after /config:

/config telegram.usernames
/config openai.prompt
/config imagine.enabled

To change a specific config property, put its name and value after /config:

/config telegram.usernames ["alice", "bob", "cindy"]
/config openai.prompt "You are an evil AI bot"
/config imagine.enabled none

When working with list properties like telegram.usernames, you can add or remove individual items instead of redefining the whole list:

/config telegram.usernames +cindy
/config telegram.usernames -bob

The /config command is only available to admins - users listed in the telegram.admins property.

Message limits

Heated discussions with the bot in large groups can lead to high usage of the OpenAI API. To avoid spending your entire budget, set message limits for groups with the conversation.message_limit config property.

You can limit the number of messages from a user over a period of time. For example:

  • 10 messages per user per hour:
message_limit:
    count: 10
    period: hour
  • 1 message per user per minute:
message_limit:
    count: 1
    period: minute
  • 30 messages per user per day:
message_limit:
    count: 30
    period: day

Setup

  1. Get your OpenAI API key

  2. Get your Telegram bot token from @BotFather

  3. Clone the repo to the server:

git clone https://github.com/nalgeon/pokitoki.git

  1. Copy config.example.yml to config.yml and specify your tokens there. Add yourself to the telegram.usernames property, otherwise the bot will be available to everyone.

  2. Start the bot:

docker compose up --build --detach

To stop the bot:

docker compose stop

To update the bot to a new version:

docker compose stop
git pull
docker compose up --build --detach

For older Docker distributions, use docker-compose instead of docker compose.

Development setup

Prepare the environment:

python3 -m venv env
. env/bin/activate
pip install -r requirements.txt

Prepare the config and data directory:

cp config.example.yml config.yml
mkdir ./data

Set tokens and other settings in config.yml.

Run tests:

python -m unittest discover

Start the bot:

python -m bot.bot
