HITL Episode 3 - Multi-Agent Systems & Model Councils Explained

How Teams of AI Agents + Model Councils Deliver Better Results with Human Oversight (Part 1 & Part 2).

Episode 3 breaks down the two biggest leaps in AI architecture happening right now: multi-agent systems and model councils. We explain LangGraph and CrewAI — the frameworks powering real-world agent teams — and show how specialized agents divide labor, cross-check each other, and solve complex problems no single model can handle alone.

Then we dive into model councils: why running multiple frontier models in parallel (as seen in Perplexity AI’s 2026 feature) dramatically reduces hallucinations and increases accuracy. You’ll learn how to combine both approaches so your AI teams stay trustworthy and aligned.

We keep the Human First focus front and center: multi-agent systems are powerful only when a human stays firmly in the loop for final decisions and ethical guardrails.
