Overview

Built two versions of an AI-powered Telegram bot — one using OpenAI GPT-3.5 and another using Google Gemini. Both handle real-time conversational AI in public Telegram groups, deployed as Netlify serverless functions for zero-cost hosting.

What I did

  • Integrated OpenAI and Gemini APIs with Telegram Bot API via TelegrafJS.
  • Implemented configurable group filtering so the bot only responds in specified Telegram groups.
  • Deployed as serverless functions on Netlify for lightweight, always-on hosting.

Highlights

  • Two separate implementations comparing OpenAI vs Gemini API workflows.
  • Serverless deployment keeping operational cost at zero.
  • Configurable per-group response behavior.
