LangChain Integration

As a provider of large language models (LLMs), Generative AI service has an integration with LangChain. LangChain is an open source modular framework for building applications that are powered by large language models (LLMs). LangChain integrations are LangChain adapters to 3rd party services. LangChain acts as a bridge, connecting the LLMs with other data sources and tools, streamlining the development of applications.
