According to Greg Brockman, OpenAI's Codex is now being used for cooking assistance directly from mobile phones (source: Twitter/@gdb, June 5, 2025). This development allows users to input cooking-related questions or commands and receive step-by-step guidance, ingredient substitutions, and real-time support via Codex's natural language processing capabilities. The integration of Codex with mobile interfaces is poised to streamline kitchen workflows, reduce user error, and enhance the at-home cooking experience, presenting new business opportunities for app developers and smart kitchen appliance manufacturers (source: Twitter/@gdb).
