In this episode, Dr. Sebastian (Seb) Benthall joins us to discuss research from his and Andrew's paper entitled “Validity Is What You Need” for agentic AI that actually works in the real world.

Our discussion connects systems engineering, mechanism design, and requirements to multi‑step AI that creates enterprise impact to achieve measurable outcomes.

• Defining agentic AI beyond LLM hype
• Limits of scale and the need for multi‑step control
• Tool use, compounding errors, and guardrails
• Systems engineering patterns for AI reliability
• Principal–agent framing for governance
• Mechanism design for multi‑stakeholder alignment
• Requirements engineering as the crux of validity
• Hybrid stacks: LLM interface, deterministic solvers
• Regression testing through model swaps and drift
• Moving from universal copilots to fit‑for‑purpose agents
