🚀 AI Tutorial – P9: Create a Local AI Telegram Bot with Ollama in Minutes

Building a Local AI Telegram Bot is one of the fastest ways to bring AI into real-world usage. By combining Ollama with a simple Python script, you can create a powerful chatbot that runs entirely on your local machine.

In this guide, you’ll learn how to deploy a Telegram bot, connect it to a local AI model, and run it as a background service for continuous operation.

🎯 Why Use a Local AI Telegram Bot?

Running a local AI bot offers several advantages:

🔒 Full privacy (no external API calls)
⚡ Instant response from local models
💰 Zero API cost
🔧 Fully customizable behavior

🔗 Part 1: Connecting the Telegram Bot

🤖 Step 1: Create the Telegram Bot

Create your bot via Telegram (BotFather) and obtain your API token:

Use this token to access the HTTP API: 8384724024:AAG7YL0LG_G70VccMYTkFMyEeyofOcArH6o

📁 Step 2: Create Bot Directory

On your Ubuntu server:

mkdir telegram-ai-bot
cd telegram-ai-bot

📦 Step 3: Install Python and Libraries

Install pip (if not available):

sudo apt install python3-pip -y

Install required libraries:

pip install python-telegram-bot requests

Upgrade if needed:

pip install python-telegram-bot –upgrade

💻 Step 4: Create the Bot Script

Create the Python file:

nano bot.py

Paste the following code:

💻

filename.bash

import requests
from telegram import Update
from telegram.ext import ApplicationBuilder, MessageHandler, filters, ContextTypes

TOKEN = ""
OLLAMA_URL = "http://localhost:11434/api/generate"
MODEL = "qwen2.5:7b-instruct"

async def handle_message(update: Update, context: ContextTypes.DEFAULT_TYPE):
    user_text = update.message.text

    data = {
        "model": MODEL,
        "prompt": user_text,
        "stream": False
    }

    response = requests.post(OLLAMA_URL, json=data)

    ai_reply = response.json()["response"]

    await update.message.reply_text(ai_reply)

app = ApplicationBuilder().token(TOKEN).build()

app.add_handler(MessageHandler(filters.TEXT & ~filters.COMMAND, handle_message))

print("Bot is running...")

app.run_polling()

▶️ Step 5: Run the Bot

Start the bot:

python3 bot.py

If successful, you will see:

Bot is running…

🧪 Step 6: Test the Bot

Open Telegram
Search for your bot
Send a message

👉 The AI will respond using your local Ollama model.

⚙️ Part 2: Run Bot as a Background Service

📍 Step 1: Determine Bot Path

Example path:

/home/bao/telegram-ai-bot/bot.py

Check current path:

pwd

🛠️ Step 2: Create systemd Service

Create service file:

sudo nano /etc/systemd/system/telegram-ai-bot.service

Add the following content:

[Unit]
Description=Telegram AI Bot
After=network.target

[Service]
User=bao
WorkingDirectory=/home/bao/telegram-ai-bot
ExecStart=/usr/bin/python3 /home/bao/telegram-ai-bot/bot.py
Restart=always

[Install]
WantedBy=multi-user.target

Save the file.

🔄 Step 3: Enable and Start Service

Reload systemd:

sudo systemctl daemon-reload

Enable service:

sudo systemctl enable telegram-ai-bot

Start bot:

sudo systemctl start telegram-ai-bot

Check status:

sudo systemctl status telegram-ai-bot

If everything is working:

active (running)
