This could just be a terrible misunderstanding that can be sorted out quickly.

AGENTIC CODE REVIEW

Coding agents moved the hard part of engineering from writing code to deciding whether to trust it, making review the most leveraged skill in software now that the old happy accident no longer holds. The 2026 data converges: Faros AI's 22,000-developer study found code churn up 861%, per-developer defect rate up from 9% to 54%, review duration up 441%, and zero-review merges up 31%, while GitClear shows 4x raw output for ~12% delivered-value gain, the gap being the review problem in one line.

A GUIDE TO AI INFERENCE ENGINEERING

Inference engineering is the discipline of running trained AI models in production efficiently. It involves working with low-level GPU code, model serving frameworks, and the cloud infrastructure that ties them together. Engineers need to optimize for a combination of latency, throughput, cost, and quality, depending on the product they're supporting. Inference engineering is now a broad speciality that any company running serious AI workloads invests in.
