LangChain-OpenAI

LangChain-OpenAI is the official integration package that connects LangChain framework with OpenAI’s suite of models including GPT-4, GPT-3.5, and embedding models. This integration package provides access to OpenAI models through LangChain’s standardized interface, enabling developers to leverage ChatOpenAI class for conversational AI, text generation, and completion tasks. The package includes specialized classes for different OpenAI services such as OpenAIEmbeddings for vector representations, and supports streaming responses, function calling, and structured output generation. LangChain-OpenAI abstracts the complexity of OpenAI API interactions while providing consistent error handling, retry logic, and configuration management for production AI applications requiring OpenAI’s state-of-the-art language models.
