vidai

Telegram summary bot that runs on Vercel. It listens for /summary (or /activity for latest activity highlights) in a group chat and uses the Hugging Face inference API to summarize recent messages. It also supports /quote to generate and send a random Greek, Chinese, or Stoic quote via the Hugging Face model directly in chat.

Setup

1. Create a Telegram bot with @BotFather and grab the bot token.
2. Create a Hugging Face account and generate an access token with access to the Hugging Face router.
3. Deploy to Vercel and set the environment variables:

• TELEGRAM_BOT_TOKEN
• HF_TOKEN
• TELEGRAM_BOT_USERNAME (optional, without the leading @, to match /summary@YourBot)

Webhook

After deployment, set the webhook to your Vercel URL:

curl -X POST \
  "https://api.telegram.org/bot<TELEGRAM_BOT_TOKEN>/setWebhook" \
  -d "url=https://<your-vercel-domain>/api/telegram"

Notes

• The bot stores the last 50 text messages per chat in memory. Vercel serverless functions are stateless, so the cache resets when the function instance is recycled.
• The summary uses the mistralai/Mistral-7B-Instruct-v0.2:featherless-ai model through the Hugging Face router. You can change it in api/telegram.js.
