Your AI coding spend bought 25% more output. Duplication rose 81%.
The New Stack published a piece stating that AI coding spend bought 25% more output, while duplication rose 81%. The two figures are presented together in the headline, pairing a gain in output with a larger relative increase in duplicated code. The article's framing treats the duplication number as the notable counterweight to the output gain, rather than reporting the output improvement alone. The available source text consists largely of page styling and layout CSS, so no further specifics are present: there is no named vendor, model, tool, sample size, measurement window, or definition of how output or duplication were counted. The published timestamp is 2026-09-14. Because the excerpt does not describe methodology or scope, the figures should be read as the article's stated headline result rather than as a benchmark with disclosed conditions. No recommendations, remediation steps, or affected-project details appear in the source.
The source indicates that AI coding spend produced more output alongside a larger rise in duplicated code, a tradeoff developers evaluating these tools would need to weigh.
