Custom LLM Client¶

"""Use a custom LLM client for red teaming.

By default, the red team pipeline creates an OpenAI-compatible client
from environment variables. You can override this with a custom client
to route through a local proxy, use a self-hosted model, or connect to
any OpenAI-compatible endpoint.

When `llm_client` is provided, ALL LLM calls in the pipeline use it:
    - Attack strategy generation
    - Adversarial prompt generation
    - Evaluation scoring
    - Model-under-test calls (static mode)

Prerequisites:
    - OPENAI_API_KEY or ORQ_API_KEY set in environment

Usage:
    OPENAI_API_KEY=sk-... python 05_custom_llm_client.py
    # or
    ORQ_API_KEY=orq-... python 05_custom_llm_client.py
