PyRIT provides automated red-teaming and adversarial testing capabilities through a modular architecture supporting multiple LLM endpoints, prompt injection techniques, and attack orchestration patterns. The framework enables systematic vulnerability discovery by chaining attacks across different AI models and services, with built-in scoring mechanisms to assess harm and risk severity. It integrates with major LLM providers and supports custom connectors for diverse AI systems, enabling security teams to conduct reproducible, large-scale adversarial campaigns.
