Example Example (Inline)

Serverless Telegram bot in webhook mode to quickly interface with OpenAI's Chat Completion API

This bot supports private chats, group chats and inline mode (tagging the bot in any chat with a query) with a confirmation button so as you don't consume tokens live.

Notes:

  • To clear or list Inline Mode context, tag the bot in chat without a query and tap on the appropriate button
  • Inline mode is capped at a 64-character limit because of callback_data limits, but it can be solved by saving the query in KV if required
  • This is mainly for personal use, if you would like to add features, do fork the repository. Do perform PRs back if you would be so kind!

Prerequisites

  • A Cloudflare account with Workers (at least free-tier) enabled
  • The Telegram bot token of a bot created on Telegram via @BotFather
  • An OpenAI API key that has the ability to use the Chat Completion API

Getting Started

Wrangler

  1. Clone this repository
  2. Run npm ci or yarn install
  3. Run npx wrangler secret put TELEGRAM_BOT_TOKEN and set the Telegram bot token
  4. Run npx wrangler secret put OPENAI_API_KEY and set the OpenAI API key
  5. Add space-delimited case-sensitive usernames to whitelist in TELEGRAM_USERNAME_WHITELIST in wrangler.toml
  6. (Optional) To allow extra lines of context, run npx wrangler kv:namespace create context and replace the ID of CHATGPT_TELEGRAM_BOT_KV and increase CONTEXT to more than 0 in wrangler.toml (will consume a lot more tokens), else remove kv_namespaces block entirely from wrangler.toml
  7. (Optional) To change the model, update CHATGPT_MODEL in wrangler.toml to whatever you want as documented at https://platform.openai.com/docs/api-reference/chat/create#chat/create-model
  8. (Optional) To include a system message to set the AI's behavior, update CHATGPT_BEHAVIOR in wrangler.toml
  9. Run npx wrangler publish to deploy to Cloudflare Workers
  10. (Optional) Enable Inline Mode for the bot on BotFather to allow inline query flow
  11. Replace {TELEGRAM_BOT_TOKEN} and {WORKERS_NAMESPACE} on the following https://api.telegram.org/bot{TELEGRAM_BOT_TOKEN}/setWebhook?&allowed_updates=%5B%22message%22%2C%22inline_query%22%2C%22callback_query%22%5D&url=https%3A%2F%2Fcf-workers-chatgpt-telegram-bot.{WORKERS_NAMESPACE}.workers.dev%2F{TELEGRAM_BOT_TOKEN} and access it on your browser

Other Optional Steps
