The release of ChatGPT's new version, GPT-4o, has sparked active promotions from the official side, but user reactions have been lukewarm. Many users are confused about the differences between the new and old versions, with some even questioning whether its performance surpasses that of competitors. The official clarification states that GPT-4o is different from previous versions and is available for free users to experience, although challenges remain with answering questions in Chinese. The new model's style is similar to Claude, enhancing protective measures that are not insurmountable. Entrepreneurs have noticed that its response style resembles certain AI writing platforms, raising questions about OpenAI's direction.
