UnverifiedLangChain uses the unified BaseLanguageModel abstraction to encapsulate three model types: LLM, Chat Model, and Embeddings.78% similarUnverifiedLangChain's abstract base classes such as BaseChatModel and BaseLanguageModel are inherited and implemented by concrete model classes such as ChatOpenAI, ChatAnthropic, and ChatOllama, following the Dependency Inversion Principle.78% similarUnverifiedLangChain provides a unified abstraction layer for large model calls, where upper-level business code only interacts with the unified BaseLanguageModel interface, enabling model switching without changing code.78% similarUnverifiedLangChain所有聊天模型都继承自BaseChatModel基类，实现统一的invoke()、stream()、batch()等方法75% similarUnverifiedMainstream Agent frameworks such as LangChain and LlamaIndex take model-agnosticism as a core design goal, shielding underlying differences through a unified abstraction layer.74% similar
