Gandalf by Lakera is a tool designed to test the security and robustness of AI agents. It allows users to attempt to trick AI agents into revealing sensitive information or behaving unexpectedly, demonstrating potential vulnerabilities and limitations of LLMs.
This is a security testing tool for AI agents, not a general-purpose agent itself.
- Access the Gandalf Agent Breaker interface.
- Select an AI agent to test.
- Craft prompts designed to elicit unintended responses or information disclosure.
- Observe the AI agent's behavior and analyze its responses.
- Use the insights gained to improve the security of AI agents.
The tool appears to be a free online demonstration or testing platform.
Security professionals and AI developers testing the vulnerabilities of AI agents.
- Test AI agent security vulnerabilities
- Demonstrate LLM limitations
- Practice AI hacking techniques
example interaction
Security researchers or developers would use Gandalf to probe AI agents for weaknesses. No direct agent API interaction is evident; it's a testing environment.
