Why each AI model gives different recommendations

Each AI model draws from different data pipelines, which is why their recommendations diverge. ChatGPT uses Bing's web index. Gemini taps Google's knowledge graph and Maps data. Perplexity runs real-time web searches for every query. Claude uses Brave search results combined with training data. A business well-represented in Google's ecosystem may rank high in Gemini but be invisible to Perplexity.
