Key Differences
ChatGPT is an AI chatbot developed by OpenAI that is primarily focused on conversational AI, generating responses to user queries in a chat format. On the other hand, LangChain is an open-source framework that helps developers build applications using large language models (LLMs). While ChatGPT is a ready-to-use AI chatbot, LangChain is a toolset for integrating and extending the capabilities of LLMs.
