AutoGPT is an open-source platform for building, deploying, and running AI agents that carry out complete workflows. Users can describe an outcome in plain English, or use its visual builder to drag, connect, branch, and inspect workflow blocks. Agents can run on demand, on schedules, or from event triggers, and the marketplace provides ready-made agents that can be added and customized. The hosted platform is a paid, usage-based service that manages infrastructure, model access, credentials, and updates; the self-hosted path is free of license fees but requires users to provide infrastructure and model API keys and maintain the deployment.
