Foundational AI literacy
Can they navigate the AI stack?
A commercial hire does not need to be a machine learning engineer. They do need to orient themselves technically: where the company's product sits, what sits above and below it, and why the current wave of AI became possible at all.
That means some grasp of the role of compute, how models, infrastructure and applications interact, and why implementation considerations — data handling, latency, accuracy, integration — are the things a buyer actually worries about.
The competency is technical orientation and curiosity, not engineering expertise.
Agents
Systems that act, not just answer
Applications
AI applied to a specific workflow
Models / training
Capability and how it is produced
Compute / infrastructure
What makes any of it possible
Layers, not a complete technical taxonomy. The competency is orientation: knowing where the product sits and what it depends on.
Layered view of the ecosystem: agents, applications, models and training, compute and AI infrastructure. Indicative layers rather than a complete technical taxonomy.
