How to Make a ChatGPT Telegram Bot (No Code, 2026)

A ChatGPT-powered Telegram bot can answer questions, support customers, or just chat - 24/7, in any language. The best part: you can set one up without coding, using your own OpenAI (or compatible) API key. Here's how to make a ChatGPT Telegram bot in 2026.

How It Works

Your Telegram bot receives a message, sends it to an AI model (GPT-4o-mini, GPT-4o, or any OpenAI-compatible provider) along with a system prompt that defines its personality, and replies with the answer. You bring the API key; the bot handles the conversation.

Step 1 - Get a Telegram Token

Open @BotFather in Telegram, send /newbot, and copy the token. (New to this? See our guide to making a Telegram bot.)

Step 2 - Get an AI API Key

Create a key at OpenAI (or OpenRouter / Groq for cheaper or free-tier models). You only pay your provider for what the bot uses - SpawnBots never charges for AI calls.

Step 3 - Connect Them (No Code)

On SpawnBots, create a Telegram bot, paste the BotFather token, then enable the AI Chat module: paste your API key (stored encrypted), pick a model, and write a system prompt like "You are a friendly support assistant for my store." Save - and your bot now answers with AI.

Tips for a Great AI Bot

• Write a clear system prompt - it controls tone, scope and accuracy.
• Start with gpt-4o-mini - fast and cheap; upgrade if you need more.
• Add an auto-reply fallback for FAQs so common questions don't cost API calls.

FAQ

Who pays for the AI? You do, directly to your provider - your key, your usage. Hosting the bot is free to start.
Is my API key safe? Yes - it's stored encrypted and only used by your bot.
Can it work on Discord too? Yes - the same AI Chat module works on Discord.
