About Gandalf: Agent Breaker
The Gandalf address now leads to Gandalf: Agent Breaker, a newer version. Here you face a set of AI agent apps and try to make them behave in ways their makers did not intend, scored by how well you do.
You play in the browser. It suits anyone curious about prompt injection and AI safety, and the early levels need no technical background.
