What is AutoGPT?

AutoGPT is the open-source project that popularised autonomous agents in 2023 and has since grown into a platform with a low-code builder, a block-based workflow model and a marketplace of prebuilt agents. You assemble blocks that perform actions - call a model, browse, read files, send a message - and connect them into an agent that runs on a trigger. It can be used through the hosted platform or self-hosted, and the codebase remains the reference many developers read when learning how agent loops are actually implemented.

FAQ

How is today's AutoGPT different?

The original was a command-line experiment. Current versions offer a visual block builder, hosting and a marketplace, so building an agent no longer requires editing a Python script.

Is it reliable enough to leave running?

Treat it as a supervised tool. Scheduled agents can work well on narrow tasks, but unbounded goals still tend to drift, so limits and checkpoints are worth setting.

Should I use the hosted version or self-host?

The hosted platform removes setup and maintenance. Self-hosting gives control and no usage fees, which suits teams with data constraints or spare engineering time.
