LLMCheckerChain verifies statements to reduce inaccurate responses using a technique called self-reflection. The LLMCheckerChain can prevent hallucinations and reduce inaccurate responses by verifying the assumptions

simply accessing LLMs via APIs has limitations. Instead, combining them with other data sources and tools can enable more powerful applications. In this chapter, we will introduce LangChain as a way to overcome LLM limitations and build innovative language-based applications.
