Measure AI coding by cost-per-merged-PR, not tokens; hybrid on‑prem routing cuts token costs
The article argues that per-token pricing poorly reflects the value of agentic coding workflows and recommends measuring cost per merged pull request (and cost per active developer) instead. It advocates hybrid architectures—routing complex planning to frontier models and routine generation to owned open-weight models (HPE reports routing routine workloads to HPE Private Cloud AI cut token costs 30–50%)—to lower marginal inference costs and keep sensitive code on-premises.
