OpenAI API
The OpenAI API provides a simple interface to state-of-the-art AI models for text generation, natural language processing, computer vision, and more.
LangChain provides an engineering platform and open-source frameworks to build, test, and deploy reliable AI agents.
LangChain describes an “agent engineering stack,” combining open-source libraries (e.g., prebuilt agent architectures and integrations) with LangSmith for observability, evaluation, and deployment of LLM/agent applications.
