Under the hood of generative AI
Under the hoodEmbedding SpaceInteractive demoEmbedding SpaceVisualize word embeddings in 2D — explore clusters, nearest neighbors, and vector arithmetic like king − man + woman = queen.Under the hoodSingle NeuronInteractive demoSingle NeuronInteractive single-neuron visualization — adjust inputs, weights, and bias, then see how activation functions shape the output.Under the hoodAttention MechanismInteractive demoAttention MechanismExplore how the attention mechanism works through an intuitive cocktail-party analogy.Under the hoodBase Model vs Instruct ModelInteractive demoBase Model vs Instruct ModelCompare how a raw base model and an instruction-tuned model respond differently to the same prompts.Under the hoodIllusion of ChatInteractive demoIllusion of ChatToggle between a polished chat UI and the raw token stream underneath — see how special tokens create the "conversation."Under the hoodThe Context Window X-RayInteractive demoThe Context Window X-RaySplit-screen X-ray of a chat app: the chat a user sees vs. the payload the model receives — memories, skills, documents, search results, and silent compaction.Under the hoodInterpreting LLMsInteractive demoInterpreting LLMsExplore how researchers peer inside language models — from polysemantic neurons to interpretable features and attribution graphs.

The Human-in-the-Loop Lab
"Don't worry, we'll just put a human in the loop." These simulations let you feel why that sentence hides so much work: automation bias, alert fatigue, anchoring, and the moral crumple zone, played out across the sectors the EU AI Act calls high-risk. Companion suite to the booklet LLM-Human Interaction Design Patterns for Operations.
Human in the loopThe Operator's DilemmaInteractive demoFlagshipThe Operator's DilemmaFive acts of being the person on night duty for an online shop: a rubber-stamp shift with a shrinking timer and a phone that keeps buzzing, an anchoring trap, confidence theater, a 3 AM kill-switch scenario, and designing the seam yourself. No IT expertise needed; every wrong AI call can be caught from the screen. Lecture mode for projectors. Includes a personal debrief.Human in the loopThe Credit DeskInteractive demoThe Credit DeskBanking: six loan applications, an AI credit score, and an ordering experiment. Does seeing the model's number first change your judgment? Two of the scores are deliberately wrong.Human in the loopThe Triage WardInteractive demoThe Triage WardMedical: work a night-shift alarm queue where one alarm out of eighteen matters, then work the same night after an evidence-based alarm redesign.Human in the loopThe WatchlistInteractive demoThe WatchlistLaw enforcement: verify facial-recognition watchlist matches against the record under a countdown. Some of the AI's matches are wrong, and one of its rejections is too.Human in the loopThe ShortlistInteractive demoThe ShortlistHiring: an AI-ranked candidate shortlist with two seeded injustices. Measures your Weight-of-Advice score: how much of the final ranking was actually yours?Human in the loopThe Border QueueInteractive demoThe Border QueueBorder control: the same risk assessments packaged three ways (raw decimals, calibrated categories, bare verdicts) and what each framing does to your referrals.Human in the loopThe DocketInteractive demoThe DocketJustice: a pre-trial docket with an "advisory only" AI risk score. One case goes wrong three months later, and the inquiry knows exactly whose signature is on the order.
The EU AI Act Lab
Tools for reasoning about the AI Act the way an engineer should: grounded in the actual text, honest about what is settled and what is still pending. Educational, not legal advice.
EU AI Act labThe NavigatorInteractive demoThe NavigatorWhere does your AI system land under the EU AI Act? Walk the real classification method — the Article 3(1) test, both Article 6 routes, the derogation filter, the profiling override — and get your risk tier, obligations with article citations, and post-Omnibus dates.EU AI Act labThe Paper TrailInteractive demoThe Paper TrailYou classified your system high-risk — now survive conformity. A five-act provider simulation: the runway decision, the Annex IV evidence pack, the assessment route, a white-label trap, and a post-market incident on a real reporting clock. Scored, with citations.
