On August 13th, OpenAI's CEO, Sam Altman, announced the latest feature enhancement for ChatGPT via social media. GPT-5 now presents users with three distinctive response modes: "Automatic," "Quick," and "Deep Thinking." Altman emphasized that the "Automatic" mode caters to the needs of the majority of users, while the new control options are designed to offer added convenience for those with specific requirements. Furthermore, the forthcoming GPT-5 version will exhibit a more engaging personality compared to its predecessor, addressing the overenthusiasm issue observed in GPT-4—a refinement based on extensive user feedback. Altman also mentioned that the team is acutely aware of the growing need for more personalized AI personality customization and is committed to achieving this in the future.
