Notes

• Max output tokens per request: 4,096 (via max_completion_tokens)
• The provider uses the official openai Python SDK
• System prompts are passed as a system role message
• User field: Every API call includes a user field set to "ai-blackteam-safety-eval" per OpenAI’s usage policy. This identifies the request as a safety evaluation, not a production user query.
• Retry with exponential backoff is automatic on API failures (3 attempts)
• If no API key is provided via config or env var, the SDK falls back to its own default resolution (e.g. OPENAI_API_KEY in the environment)
