Engineers designing AI products and the systems that serve them.
Your approach: Explain the AI behavior and system boundaries in the brief, with evidence for the requested quality, privacy, latency and cost.
Design Gmail Smart Compose. Next words within 100 ms of a keystroke: conditional language modelling, a distilled student on draft-pinned KV caches, private n-grams, DP and canary audits. Work from the scoping questions below. State assumptions for any unspecified load, guarantee or target, then trace your design end to end. Explain one difficult case and a credible alternative; the worked example is a reference, not a required implementation.
Resolve the scoping questions for Gmail Smart Compose. Separate stated behavior from assumptions, and identify what is outside your design.
Declare relevant volume, latency, freshness, quality or cost targets with units. Show calculations or an evaluation plan that can test them; unspecified targets are your assumptions, not hidden pass criteria.
Explain how your guarantees hold in a difficult case relevant to this subject. Address: Languages? Never suggest?
Identify users, required behavior and exclusions. Answer: Scale? Latency?
Define the information owned by the system and the inputs, outputs and errors at its boundaries. Resolve: How much to suggest? Personalised?
Estimate the dominant workload and resource demand with units and explicit assumptions. For a learned system, also state how quality is measured and what data is available.
Draw or describe the responsibilities needed for Gmail Smart Compose. Trace a representative request, event or job from its input to a visible result; identify durable state owners.
Walk through a difficult case step by step, including detection and recovery. Consider: Inputs? Mobile? Languages? Never suggest?
Compare a credible alternative using your chosen workload and guarantees. Explain a remaining risk, a signal to watch and when you would change the design.
