Cheap Per Token, Expensive Per Task: Why the Lowest-Priced AI Coding Model Can Cost More

Engineering teams pick AI coding models on price per token. The invoice does not arrive in tokens. It arrives in finished tasks. A model that looks 60% cheaper per token can cost more per merged PR once retries, context reloading, and correction time are counted. Here is how to measure the number that actually hits your budget.

When AI Coding ROI Goes Negative: How to Detect It Early and What to Do

Most AI coding ROI frameworks assume the result will be positive. Some pilots end at 90 days with flat or negative numbers. Here is how to detect the signal before it costs you a full quarter, and what to do when the number does not work.

What the EU AI Act Means for Engineering Teams Using AI Coding Tools

The EU AI Act's full provisions apply from August 2026. Most engineering teams using AI coding tools have no documentation of which code was AI-generated, no PR-level attribution, and no audit trail. Here is what is required and how to close the gap.

Why your AI coding pilot looked great at 30 days and failed by 90

The 30-day checkpoint is where most AI coding pilots get their budget renewed. It is also the point most likely to show you a number that will not survive contact with reality.

How to measure ROI on AI coding agents like Claude Code and Cursor

Most engineering teams cannot answer the CFO question: what value are we actually getting from Claude Code, Cursor, and GitHub Copilot? Here is a measurement framework that produces numbers finance can verify.
