Can I reverse engineer ChatGPT?
An original rebuild of a ChatGPT-style MVP is rated 5/5 (very complex) and would take an estimated 12–18 months. Hardest engineering problem: Replicating the underlying large language model training pipeline and inference optimization that powers context-aware, real-time conversational responses. Open-source projects such as LangChain, LlamaIndex, RAG are a practical starting point.
◈ How you might build it
Start with the smallest useful workflow: authentication, a focused ai experience, and persistent user data. Layer on collaboration, integrations, background processing, and production reliability as the product grows. The stack below is a suggested approach, not a verified description of ChatGPT's internals.
