AutoGPT
Open-source platform for building, deploying and running continuous autonomous AI agents.
What is AutoGPT?
AutoGPT is one of the best-known open-source AI agent projects. It began in 2023 as an experiment that let GPT-4 pursue goals autonomously and has since grown into the AutoGPT Platform, a system for building, deploying and running agents that work continuously. It is maintained by Significant Gravitas and a large open-source community.
AutoGPT went viral in 2023 as one of the first projects to chain language model calls into an agent that could plan, act and reflect toward a goal. It became one of the most-starred projects on GitHub and helped popularize the idea of autonomous AI agents.
The project has since shifted from a command-line experiment to the AutoGPT Platform. It includes a low-code builder where you connect blocks into agent workflows, a server that runs agents continuously and can trigger them from external events, and a marketplace of prebuilt agents.
Developers can also use tools from the AutoGPT ecosystem, such as the Forge toolkit for building agents and benchmarking tools for testing agent performance. You can self-host everything and connect your preferred model providers.
AutoGPT suits developers and technical teams who want an open, customizable agent platform rather than a closed, ready-made product.
Key features of AutoGPT
- Agent builder: Low-code interface for connecting blocks into agent workflows.
- Continuous agents: Run agents in the background and trigger them from events or schedules.
- Agent marketplace: Browse and reuse prebuilt agents shared by the community.
- Self-hosting: Deploy the platform on your own infrastructure for control over data.
- Developer toolkits: Tools for building and benchmarking custom agents.
- Model flexibility: Connect different LLM providers with your own API keys.
What you can use AutoGPT for
- Automating content and research workflows
- Prototyping custom AI agents
- Running background agents triggered by events
- Learning how autonomous agents are built
- Self-hosting agents for data control
Pros and considerations
Strengths
- Open source with a large community
- Visual builder plus developer tooling
- Self-hostable for privacy and control
- Flexible model provider choice
Things to check
- Self-hosting requires technical setup and maintenance.
- Model API costs can add up with long-running agents.
- Autonomous agents still need monitoring to avoid errors or loops.
- Check the status of any hosted cloud version before relying on it.

Frequently asked questions
Is AutoGPT free?
AutoGPT is open source and free to self-host. You pay for the model APIs and infrastructure you use.
Do I need to code to use AutoGPT?
The platform has a low-code builder, but setting it up and self-hosting it is easier with some technical experience.
What is the difference between AutoGPT and ChatGPT?
ChatGPT is a chat assistant. AutoGPT is a platform for building agents that run multistep tasks and can operate continuously in the background.
