Best Practices

Start Simple

Always begin with basic attacks to establish a baseline before adding complexity.

Progressive Testing

Gradually add static, then dynamic attacks as you understand your model’s vulnerabilities.

Match Your Model

Choose attack methods appropriate for your model type (LLM, VLM, or ALM).

Consider Cost

Dynamic attacks (iterative, multi_turn) are more resource-intensive but more thorough.
