Interactive learning
See how AI systems work, one step at a time.
Learn It Fast turns the abstract — attention, retrieval, tool-use loops, prompt caching, multi-agent coordination — into interactive, inspectable simulations. Pause, step, and read the cost at every stage.
Simulators
Step through how LLM internals, RAG, agents, prompting, and cost actually work — with live metrics at every step.
Explore simulators→Agent Designer
Compose an agent from tools, memory, and a control loop, and see the token + cost implications as you build.
Open the designer→Architectures
Reference diagrams for common AI system patterns — retrieval, multi-agent, routing, and more.
