Welcome to LlamaIndex 🦙 !
LlamaIndex (GPT Index) is a data framework for your LLM application.
LLMs are a phenomenonal piece of technology for knowledge generation and reasoning. They are pre-trained on large amounts of publicly available data.
How do we best augment LLMs with our own private data?
We need a comprehensive toolkit to help perform this data augmentation for LLMs.
That’s where LlamaIndex comes in. LlamaIndex is a “data framework” to help you build LLM apps. It provides the following tools:
Offers data connectors to ingest your existing data sources and data formats (APIs, PDFs, docs, SQL, etc.)
Provides ways to structure your data (indices, graphs) so that this data can be easily used with LLMs.
Provides an advanced retrieval/query interface over your data: Feed in any LLM input prompt, get back retrieved context and knowledge-augmented output.
Allows easy integrations with your outer application framework (e.g. with LangChain, Flask, Docker, ChatGPT, anything else).
LlamaIndex provides tools for both beginner users and advanced users. Our high-level API allows beginner users to use LlamaIndex to ingest and query their data in 5 lines of code. Our lower-level APIs allow advanced users to customize and extend any module (data connectors, indices, retrievers, query engines, reranking modules), to fit their needs.
