I noticed that most of my friends, incuding myself, just use regular ChatGPT because it is simple and works well. We tried custom version and plugins for a while, but no one really sticks to them. Custom versions can be useful for specific tasks like research or work, and plugin can help with things like gathering informations or making charts but for daily use, the regular ChatGPT is enough for us.
I use one that I created all the time, mostly because of a custom integration.
I think I could probably re-write the integration another way, but since it works, there hasn’t been a big reason for me to do so. At the same time, I’ve noticed recently that the model is limited to 4o, which is starting to be a bit outdated. It still does the work I need it to do fine, but I wonder how much more dynamic a newer model might be.
I use a private custom gpt nearly every day and mine is running on gpt 5.2 which i don’t really need as my usage case is very basic. I am surprised that yours is locked in to 4o.
I use custom GPT’s and find them very useful, in some cases are night and day comparing to generic chats.
I have 4 public GPT’s for everyone to use, 5 private - it’s the whole systems thinking chain.
I wrote an article about my journey to custom GPT’s: https://medium.com/@viktor.jevdokimov/making-thought-durable-d5851acc12bf
