Build Your Own ChatGPT Clone in 30 Minutes (Flask + Ollama + Llama 3)

In this tutorial, we build a ChatGPT Clone in just 30 minutes using Flask, Ollama, and the Llama 3 AI model. Blog Links - https://selftuts.in/build-chatgpt-clone-in-30-minutes/ - https://selftuts.in/how-to-run-llama-3-locally-using-ollama/ - https://selftuts.in/install-python-virtualenv-windows-mac-linux/ Instead of using the OpenAI API, we will run everything locally on our machine using Ollama. By the end of this video, you will have a fully working AI chat interface with: ✔ ChatGPT-style UI ✔ Streaming AI responses ✔ Markdown rendering ✔ Code syntax highlighting ✔ Local AI model integration This project is perfect for developers who want to understand how modern AI chat interfaces work and how to connect a frontend UI with a local LLM backend. We will build the backend using Flask and connect it to the Ollama server running the Llama 3 model. If you are learning AI development, LLM applications, or building your own AI tools, this tutorial will help you understand the complete architecture. 00:00 Hook – ChatGPT Clone Running Locally 00:20 What We Are Building 00:50 Blog Tutorial Overview 01:20 Prerequisites (Python + Ollama) 02:05 Architecture Overview 04:20 Project Setup & Virtual Environment 09:10 Building Flask Backend API 13:30 Building the Frontend Chat UI 18:40 Running the ChatGPT Clone 23:00 Adding Streaming Responses 30:40 Markdown Rendering & Code Highlighting 36:40 Final Demo 36:50 Next Improvements (Memory + Multi Chat) Subscribe for more AI engineering tutorials, coding projects, and developer tools. 🔥 Next Video: Adding conversation memory and multi-chat support. #AI #ChatGPTClone #Ollama #Llama3 #PythonAI
