But not all platforms are being used in the same way. While the OpenAI-NBER study (September 2025) has highlighted the worldwide use of ChatGPT by the general public, Anthropic is publishing, with its <em>Economic Index<\/em> a detailed analysis of the adoption of Claude, focusing on geography and companies (<a href=\"https:\/\/www.anthropic.com\/research\/anthropic-economic-index-september-2025-report\" target=\"_blank\" rel=\"noopener\">Anthropic, <em>Economic Index September 2025 Report<\/em><\/a>).
