Don't Use LangChain or LlamaIndex For GenAI Applications

Описание: I explain why you should not use LangChain or LlamaIndex when developing GenAI applications. Both langchain and llamaindex make your codebase much more complex than necessary and you spend more time learning the framework itself instead of learning how ai assistants and RAG actually work. Instead of LangChain I would recommend you to just use the ChatGPT api as this is much simpler and you can actually debug your assistant when something goes wrong.
