Telegram Bot with Local AI: No API Costs

Description and use

Build a Telegram bot that uses a locally hosted Llama3.2 model via Ollama to avoid API costs and keep data private.

Problem

Cloud AI APIs cost money per token and expose data to third‑party servers.

Outcome

A Telegram bot that answers questions using a locally hosted Llama3.2 model, eliminating API costs and ensuring data privacy.

Workflow

• Install Ollama and pull the desired model: brew install ollama && ollama pull llama3.2
• Start the local server: ollama serve
• Create a Python helper function to POST to http://localhost:11434/api/generate with the model and prompt
• Use the helper in the Telegram bot to answer user queries without any API key

Evidence

Now you have a GPT-4 level model running on your MacBook. Free. Private. Fast.
