The new feature 'Model Arena' of 360AI Assistant allows users to choose from multiple large models, input the same prompt, and intuitively compare the outputs of different models. By evaluating model performance through a rich question bank, it enhances objectivity and comprehensiveness. This feature is combined with the new AI Assistant floating button in the 360 Browser, integrating products from 15 top large model companies, providing a platform for free selection and comparison, thereby enriching the user experience.
