GitHub says Copilot improves code quality - but are AI coding tools actually producing results for developers?
Briefly

Uplevel's investigation found that the performance of developers using generative AI, specifically GitHub Copilot, has largely remained unchanged, contradicting claims of enhanced efficiency.
Uplevel's research with 800 developers showed no significant impact on efficiency metrics from Copilot, challenging industry narratives of increased coding speed and quality.
The study recorded only a 1.7 minute decrease in average cycle time, a change deemed inconsequential in the context of overall performance metrics.
Despite GitHub’s claims of a 55% increase in coding speed due to Copilot, the Uplevel study found no meaningful difference in coding performance.
