Stuck? Show a way to structure it+

01Clarify objective, users, constraints, and failure tolerance.
02Cover fusion, memory bandwidth, occupancy, numerics in a causal structure.
03Compare at least two credible approaches.
04Specify evaluation, rollout, monitoring, and rollback.

Reference answer

strong answer

I would begin by defining the target outcome and acceptable failure boundary. For inference kernels: judgment, I would analyze fusion, memory bandwidth, occupancy, numerics, compare alternatives on quality, latency, cost, and risk, and validate on representative slices before a monitored rollout.

fusion
memory bandwidth
occupancy
numerics

Requires scenario-specific numbers
Should include relevant personal experience

alternative answer

I would start with the riskiest assumption in inference kernels: judgment, create the cheapest discriminating experiment, then use the evidence to choose an architecture and release threshold.

experimentation
risk-first sequencing
decision clarity

Needs deeper implementation detail
