LlamaIndex is a framework for building context-augmented large language model (LLM) applications. It enables you to augment the model with domain-specific data to customize it and improve its responses to your use case. You can use this framework to build a question-answering chat bot, a document understanding and extraction application, or an autonomous agent. The framework provides tools to ingest data, process it, and implement query workflows that combine data access with LLM prompts.

As codebases mature, they grow in complexity. As time goes on, higher complexity increases the cost of changing and scaling a system. Scalability is an essential feature of enterprise software. End-to-end integration testing is not a very scalable process, especially when you are dealing with multiple systems.
