LangChain and OpenAI Open the AI Path: Python also plays a major role in building modern AI applications. Developers can use OpenAI tools and APIs to add AI capabilities to applications, while frameworks such as LangChain help connect language models with data, tools and application workflows. These technologies can support chatbots, AI assistants, retrieval systems and other applications. The broader Python ecosystem means developers can combine AI libraries with data processing, web development and automation tools in a single project.
