I see a lot of value in the form of convenience from GPTs. It helps to avoid repeating the intial prompts for things that you want to do multiple times. For eg: I created a GPT for stock earnings call report anlaysis [1] which helps me to get the analysis or summary by just entering the company name or stock ticker. This is at least a huge improvement in UI which makes me comeback and use it frequently.
