The saved threads list for The Assistant doesn't list the models that were used in every thread. Having the information would prove useful.
This could be done by adding a line below each thread in the list with the list of models used in it, separated by commas, in small font. There could very well be a better way of implementing this in the UI as well; not my specialty!
I often like to compare the output of different models to my initial question, and so I create a new thread for every model tested. If I were to simply switch the model in the same thread, the new model used will have access to the history of outputs from the other models, hence making the comparison unfair. Then, when I open the threads list to compare the outputs, all the threads have the same name, so I can't know which model corresponds to which thread unless I open every thread to check.
