AutoGPT is a pioneering open-source autonomous AI agent that chains together GPT-4 capabilities to complete complex, multi-step tasks with minimal human intervention. It can browse the internet, write and execute code, manage files, and interact with external services — all in pursuit of a user-defined goal. AutoGPT spawned the modern AI agent movement and remains the most-forked AI project on GitHub, enabling developers to build self-directed AI workflows.
