Autonomous Agents is an open-source Python library designed to simplify the creation of autonomous AI agents powered by large language models. By abstracting core components such as perception, reasoning, and action, it allows developers to define custom tools, memories, and strategies. Agents can autonomously plan multi-step tasks, query external APIs, process results through custom parsers, and maintain conversational context. The framework supports dynamic tool selection, sequential and parallel task execution, and memory persistence, enabling robust automation for tasks ranging from data analysis and research to email summarization and web scraping. Its extensible design facilitates easy integration with different LLM providers and custom modules.

LangChain is a developer-focused framework designed to streamline the creation of intelligent AI agents and applications. It provides abstractions for chains of LLM calls, agentic behavior with tool integrations, memory management for context persistence, and customizable prompt templates. With built-in support for document loaders, vector stores, and various model providers, LangChain allows you to construct retrieval-augmented generation pipelines, autonomous agents, and conversational assistants that can interact with APIs, databases, and external systems in a unified workflow.
