Study: AI Coding Assistants Boost Developer Productivity by 55%Study: AI Coding Assistants Boost Developer Productivity by 55%

A comprehensive study across 5,000 developers at 50 companies found that AI coding assistants improve productivity by 55% on average, measured by task completion time. The biggest gains were in boilerplate code generation (78%), debugging (62%), and test writing (58%). However, code review time increased by 15% as developers need to verify AI-generated code. The study recommends treating AI assistants as junior pair programmers - helpful but requiring oversight.
