txtai is an all-in-one AI framework designed for semantic search, LLM orchestration, and language model workflows. It targets developers and researchers building applications like autonomous agents, retrieval augmented generation (RAG) systems, and complex multi-model pipelines. The framework's core benefit is its unified approach to integrating various AI capabilities, simplifying the development of sophisticated AI-powered applications.

How It Works

txtai's foundation is an embeddings database that combines vector indexes (sparse and dense), graph networks, and relational databases. This architecture enables powerful vector search and acts as a knowledge source for LLM applications. It supports creating embeddings for diverse data types (text, audio, images, video) and orchestrating complex tasks through pipelines and workflows, which can be chained together and aggregated with business logic. Agents built on this framework can autonomously solve problems by connecting these components.
