Code shipped 53% faster, 53% more likely to pass tests
GitHub’s controlled 2024 RCT (202 developers, ≥5 years experience): Copilot users were 53% more likely to pass all unit tests, with small-but-significant gains in readability, maintainability, and conciseness. This is the most rigorous AI productivity study published.
10,000 lines migrated in 4 days
Stripe pointed Claude Code at a Scala-to-Java migration estimated at 10 engineer-weeks. It shipped in four days. Bounded, well-specified, mechanical work is where AI consistently delivers right now.
16,000 research hours / year reclaimed
A top-five pharma replaced internal document search with Claude on Bedrock and reclaimed an estimated 16,000 research hours annually. AI didn’t have to be brilliant — it just had to beat SharePoint search.
87% faster customer support resolution
A major rideshare platform put a frontier model in front of its support pipeline as a triage + draft layer (humans still own complex resolution). Average resolution time dropped by roughly seven-eighths.
