DECODE captured 53,600+ in-IDE modifications to AI-generated code from 1,000+ developers across Python, TypeScript, and JavaScript. Most edits land within 15 minutes of accepting a completion, and roughly 31% of editing sequences end with the completion removed. Acceptance-rate telemetry substantially overstates real value, which anyone who has watched their own accept-then-delete pattern already suspected. Fine-tuning a 3B open model on DECODE beat much larger frontier models at predicting these edits.
