Creating a free Telegram bot with AI on Groq API

If you’ve already made a simple bot on Telegram, now let’s make it *smart with answers from Groq (very fast and free AI).

What you need in advance:

• Installed Codex app (Cursor, VScode)
• Groq API key (free)
• Telegram

## Step 1. Install Codex app (you can use analogues)

1. Go to https://openai.com/codex
2. Press Download
3. Open the downloaded file → install
4. Launch the application
5. Sign in with ChatGPT – use your login/password from chatgpt.com
6. Done! Codex will open as a chat/agent window.

## Step 2. Get a Groq API key

1. Go to https://console.groq.com/keys
2. If there is no account – Sign Up (email + password + confirm mail)
3. Come in
4. On the main or on the left menu, find API Keys
5. Press Create API Key
6. Give me a name like TelegramBotGroq
7. Press Create
8. Copy the key (starts with gsk_...) - save it in notes. It only shows once!

## Step 3. Create a Telegram bot and take a token

1. On Telegram, find @BotFather
2. Write /newbot
3. The name of the bot is any, such as "Groq Smart Assistant."
4. Username – ends in bot, such as @GroqVibeBot or @SiauliaiAIBot
5. BotFather to give token: 1234567890:AAFxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
6. Copy the token

## Step 4. Give Codex the task - create and launch a bot!

1. In Codex app, open a new window / project (New Thread or just chat)
2. Enter ** this prompt in its entirety** (you can and should adjust):

Create and run a full Telegram bot in Python with Groq API integration for smart answers. Do it yourself inside Codex without me doing it.

Requirements:
Libraries: python-telegram-bot (async version), requests, python-dotenv
- Files: bot.py + .env
- In .env: BOT TOKEN=telegram token here and GROQ API KEY=groq key here (with placeholders)
- Bot:
- /start: Hello! I'm a Groq AI bot. Ask any question 🙂
- /help: "Just write - I will answer quickly through Groq"
- any message: first, "I think ..."  , then query to Groq, reply to the user
- Groq: endpoint https://api.groq.com/openai/v1/chat/completions
Headers: Authorization: Bearer
Body: {"messages": [{"role": "user", "content": text}], "model": model}
Choose 2-3 Groq models (llama3-8b-8192, llama-3.1-70b-versatile, mixtral-8x7b-32768, gemma2-9b-it, etc.)
- Before the final code, test each model on the query "Hi, tell a joke!" - show the results in the chat (which answered normally, which with an error)
Choose the fastest and most stable bot model
- Handle Groq errors: "Groq is busy now " Try later"
- Launch: polling (app.run polling())
At launch: print("Bot launched!") Write him on Telegram.
- Code with comments in Russian
Create a project yourself, install dependencies in a sandbox, test models, run a bot
- After launch, say "Bot working!" Check Telegram.

GROQ API KEY for model testing: insert your key here (replace in .env)

(In the prompt, insert your real Groq key for model testing only - Codex will test privately, in the final .env key will be a placeholder.)

3. Send a prompt (Enter or Run/Start Agent button)
4. Codex will start working:
   • Create a sandbox project
   • Install the packages
   • Tests Groq models (you will see in the chat which worked)
   • Write code
   • Launch the bot
   • The logs will say, "Bot's running!"

## Step 5. Final steps in .env and test

1. Codex will create .env something like this:

BOT TOKEN=your telegram token here
GROQ API KEY=your gsk key here

2. Open .env in Codex (or Finder) → insert your keys → save

3. If the bot stops - in Codex write: "Reset the bot"

4. In Telegram, find a bot → /start → ask a question

The bot must respond via Groq

## If there's a problem

• The model doesn’t work in Codex: “Groq model broke, here’s the mistake: [insert].” Choose another and restart
• Key Error: "Check .env and restart"
• Copy the log from Codex and paste it into a new prompt: "Fix this mistake"

Your bot with Groq AI launched fully automatically via Codex
