Just stumbled across something interesting: OWASP quietly released a new guide focused entirely on AI system testing. It's called the AI Testing Guide (AITG). Some of the stuff it digs into: Prompt injection and adversarial attacks, Privacy leaks from model outputs, Fairness, bias, and explainability testing, Data drift and real-world robustness and Model reproducibility.

What I liked is it actually gives a practical structure for testing models in production, especially for teams shipping LLMs or recommendation engines.
