ChatGPT EnterpriseEmployee deployment
Apr 20, 2026

OpenAI's case study says Hyatt made ChatGPT Enterprise available across its global corporate and hotel workforce, with onboarding and training.

Access does not establish active use by every employee; included Codex access is not a separate coding adoption measure.

Comments are paraphrased. Employee deployment, product integrations, pilots, and hiring statements have different scopes. A headquarters location does not locate every employee or prove state-wide tool popularity. Unnamed providers remain undisclosed. This is a selected evidence sample, not an exhaustive company census.

Behind the figures

Current-use question: “In the last two weeks, did this business use Artificial Intelligence (AI) in any of its business functions?”

The recent average is the arithmetic mean of available current-use estimates for the last six periods, Jun 29, 2026–Sep 20, 2026. It is calculated from the source workbook and is not an official Census aggregate. Standard errors are published Census values. The AI question broadened in November 2025, so the chart starts with the revised series.
