Grok 3 and ChatGPT, both cutting-edge AI models, differ significantly in their training data. ChatGPT relies on publicly accessible internet data, including books, articles, and websites, to train its neural networks[2][5][8]. OpenAI uses a dataset called Common Crawl, which consists of billions of web pages[5]. In contrast, Grok 3 incorporates real-time data from X (formerly Twitter), providing it with access to current events and conversations[7]. The training of Grok 3 also involves synthetic data to ensure logical consistency in its outputs[4]. Additionally, Grok 3's training dataset reportedly includes legal case filings[9].
