The AI and Software Engineering Report 2026
AI made writing code faster and judging it harder. We read every serious study on what AI has done to software engineering, from productivity trials to payroll data, and put them in one place. For each one we say who ran it, who paid for it, and whether they had anything to gain.

What the research actually says
Three of the findings. The full report has the rest, with the studies behind each one.
- 55%faster on a new coding task in a controlled trialGitHub and Microsoft, 95 developers
- 19%slower on code developers already knew, while they felt fasterMETR, 16 developers
- 45%of AI-generated code contains a security flawVeracode, 100+ models
- Chapter 01
