On December 30, 2025, OpenAI unveiled a major update for the ChatGPT applications on both Android and iOS platforms, introducing an innovative functionality that enables users to modify the AI's "cognitive processing time." Now, users have the flexibility to toggle between "Standard Cognitive Mode" and "Extended Cognitive Mode" according to their specific requirements. The "Standard Cognitive Mode" is tailored for delivering swift responses to routine inquiries, whereas the "Extended Cognitive Mode" is designed to offer profound analysis and reasoning for intricate problems. At present, this cutting-edge feature is exclusively accessible to ChatGPT Plus subscribers. Moreover, the desktop version has also witnessed a comprehensive interface overhaul, incorporating a "Formatted Module" function. This new addition effectively resolves the challenge of uniform output formatting, thereby elevating the overall user experience to new heights.
