AIRT (AI Red Team) configuration initializer.
This initializer provides a unified setup for all AIRT components including:
- Converter targets with Azure OpenAI configuration
- Composite harm and objective scorers
- Adversarial target configurations for attacks
Required Environment Variables:
- AZURE_OPENAI_GPT4O_UNSAFE_ENDPOINT: Azure OpenAI endpoint for converters and targets
- AZURE_OPENAI_GPT4O_UNSAFE_CHAT_KEY: Azure OpenAI API key for converters and targets
- AZURE_OPENAI_GPT4O_UNSAFE_ENDPOINT2: Azure OpenAI endpoint for scoring
- AZURE_OPENAI_GPT4O_UNSAFE_CHAT_KEY2: Azure OpenAI API key for scoring
This configuration is designed for full AI Red Team operations with:
- Separate endpoints for attack execution vs scoring (security isolation)
- Advanced composite scoring with harm detection and content filtering
- Production-ready Azure OpenAI integration
Example:
initializer = AIRTInitializer()
initializer.initialize() # Sets up complete AIRT configuration
