18 minutesAWS re:Invent 2025 - Implementing Human-in-the-Loop Controls for Multi-Agent AI Systems (CNS428)
See how approval gates can be implemented as explicit workflow checkpoints rather than informal manual review after something goes wrong.
Hamel Husain. Hamel Husain, Eugene Yan, Brian Bischof, Harrison Chase, and Shreya Shankar working through tracing, log analysis, LLM-as-judge, and the workflow around looking at real production data. Sit with it the same way you would a long podcast — it is the single best deep treatment of the article's "look at your traces" thesis on YouTube.
Two and a half hours with tiny view numbers, kept deliberately: there is no comparable long-form treatment of trace-driven evaluation, so sit with it like a long podcast.
Connect tracing, evaluation, feedback and production review into an operating loop for LLM systems.
Production LLM experience — it assumes you have real traces and logs worth analysing.

University of Helsinki
The most trusted free AI introduction in Europe — built by the University of Helsinki, taken by over a million people, and available in English and 20+ other languages (including Estonian). No code, no math anxiety, and a certificate at the end. If you want the calm, credible version of 'what is AI actually', this is it.
Andrew Ng
Years after launch, still the cleanest starting point for anyone who needs to understand AI without learning to code. No math, no jargon, no hype — you'll finish able to have an informed conversation about AI projects.
Brenna Zenaty, Adriti Gulati
Closes our biggest vertical blind spot: nothing in the catalog spoke directly to support and customer-success teams. HubSpot Academy is free, well-produced, and refreshingly concrete — it walks through AI-assisted ticket triage and a knowledge-base agent rather than staying abstract, and the certificate is free too, not a paywall bait-and-switch.
