ChatGPT vs Perplexity: Sam Altman applauds Aravind Srinivas’ deep research AI, says ‘proud of you’

OpenAI CEO Sam Altman recently praised Perplexity AI CEO Aravind Srinivas for creating a rival Deep Research tool based on China’s DeepSeek AI, following OpenAI’s release of its own Deep Research feature for ChatGPT. While OpenAI’s Deep Research aims to offer more accuracy, Srinivas’s version is positioned as faster and cheaper, though slightly less precise.
