Claim LD02-HQ-C14 (v1.0)

In a preregistered experiment with 758 BCG consultants, GPT-4 users completed 12.2% more inside-frontier tasks, worked 25.1% faster and produced roughly 30–34% higher human-graded quality, but were 19 percentage points less likely to be correct on a task outside the tested frontier.
