Please allow users to choose their own models.

Many people seem to be dissatisfied with the new AI model. However, some people like new changed models, and they have their own advantages.

However, there are many people who want the previous model, so this place, like other AI chatbot sites, should have allowed users to choose their own AI models. AI models may change again someday, and if the new model is not very good, many users may be dissatisfied, so I think we should do so for the future.

Please start developing and add the model selection function so that users can choose the previous AI model and the current AI model as they want.
