Summary
A short educational video on LLM safety for application builders. It walks through four things that can go wrong with LLM apps — off-topic use, hallucinations, jailbreaks, and data leaks — each illustrated with a real-world incident (Klarna, Air Canada, Chevrolet, DPD). It then presents a defense strategy: start with risk assessment, then apply three lines of defense — product design choices, real-time guardrails, and safety testing through red-teaming — treating safety as an ongoing process, not a one-time gate.

- Risk 4: Data leaks
- Risk assessment
- First line of defense: product design choices
- Second line of defense: guardrails
- Third line of defense: safety testing and red-teaming

Key takeaways
- LLM failures are a liability, not just a UX problem: a court ruled Air Canada had to compensate a customer after its chatbot gave refund advice contradicting company policy.
1:18 - Hallucination is inherent to LLMs — "not a bug but a feature" — so never rely on them for factual information without grounding (e.g., RAG with quoted sources).
1:01 - Jailbreaks have real business consequences: a Chevrolet chatbot was manipulated into "selling" a car for $1, and a DPD bot was prompted into swearing and mocking its own company.
1:48 - Defense is layered: risk assessment first, then product design (classifiers, constrained data access, human-in-the-loop), then guardrails on inputs and outputs — accepting that guardrails add latency and can't cover everything.
2:49,4:05 - Test the whole system, not the model alone: red-team with a dataset of adversarial prompts and verify the app consistently denies them.
4:21,4:38 - Safety is ongoing — new attack types keep emerging, so apps in production must be re-tested continuously.
