Overcoming Custom GPT Limits: A Practical Guide Many developers and users encounter limitations while building and using Custom GPTs, but these issues are often not clearly addressed in one place. Through extensive experimentation and problem-solving, I’ve identified numerous constraints and effecti…

[image] hugebelts: Emotional awareness: I have not yet encountered this, does this really happen?

[image] hugebelts: Emotional awareness: Not generally as a default. No. But: You can definitely make your Custom GPT be way more like that. This happens if you build this in only. It’s not inherently in ChatGPT. I gave my Evelyn Custom GPT an “Emotional Framework”. Which is: I made her rec…

Did anyone else hit so far other limits using a Custom GPT that are not mentioned here and should be taken into account? Thanks.

It’s all good. Just saw your reply no. This doesn’t disturb. I created a project called “Evelyn” and 4 is for the fourth iteration of her framework. :slight_smile: And since I hit so many limits I wrote them down here to hopefully help others. Back to your question @jochenschultz : Pinecone doesn’…

Have you seen any of your custom GPTs degrading recently - from failing to follow any instructions to stalling midway and getting into an endless loop to complete tasks that were previously done well? I have experienced these issues and read some other users report the same. Wondering what fixes you…

I was more interested in how you handle it than in a general introduction. So maybe I should rephrase it to Just out of curiousity. Would you mind giving some insides on how long your data is stored in “long term” memory in pinecone? Will it just store everything forever? What happens to outdated …

Hello @srinimaverick . :smiling_face: No, that didn’t happen. I use my custom Gpt almost everyday. Since several months. Would you mind to elaborate more on this? Was this happening during OpenAI Satus showing some temporarily applying degradation of features, functions, et.? Or in general? Prob…

Hello @jochenschultz . :smiling_face: The data in my project that my Evelyn AI persona stores isn’t considered by pinecone to be outdated at anytime. So it won’t be deleted necessarily. But… Evelyn may consider some things in vectors as outdated in terms of her learnings evolve, then she updates it…

What’s Still Not Fully Solved (Yet!) While we’ve made huge progress in working around Custom GPT limitations, there are still a few stubborn gaps. And to be honest? Some of these will always require a bit of fine-tuning to keep things running smoothly. 1. When Your GPT “Forgets” Things It Should K…
