## AI overview

The article argues that experienced developers' measured performance with AI coding tools shifted from roughly 19% slower in mid-2025 to roughly 18% faster by early 2026. It attributes the change to better tools and developers gaining experience directing and reviewing generated code, while noting sample-selection caveats.

## Source excerpt

That puts me on one side of a heated argument. A well-known METR study in 2025 found experienced developers were around 19% slower with AI while sure they were faster, and skeptics passed it around as proof.
