A layered classification lattice removes identifying information before categorizing individual-plan messages. Country-level aggregates pass small-group suppression and statistical noise before publication. Enterprise and Codex remain separate; the footer warns that usage does not measure productivity.

Summary: OpenAI’s Signals analysis covers individual-plan ChatGPT messages across 74 countries and reports that the ten most common work activities fell from 56.0% of activity in early 2025 to 51.1% in late 2026. The privacy-preserving aggregate excludes enterprise and Codex usage, so it describes consumer-plan behavior rather than organizational adoption.

Why it matters: You will learn how to use activity-level adoption data without overclaiming: distinguish message share from business value, separate individual from enterprise use, identify emerging tasks and pair aggregate trends with workflow-specific quality, cost and risk evidence.
