Custom GPT vs ChatGPT. Are custom GPT worth it?

Hi,

I’ve created 14 MyGPTs so far.
Some I know for sure that I’m the only one using them, but others I don’t. Even though I have one or two that have more than 100 conversations, I’m not sure they’re not all mine :blush:. That’s one issue, I don’t think it’s possible to know if anyone other than ourselves is using the GPTs.
I often criticise the behaviour of GPTs because they’re not too constant.
I also try and use many GPTs created by others and some are awesome.
But yesterday I wasn’t able to accomplish what I needed with some custom GPTs so I tried the same with plain ChatGPT-4.
Even though it’s not specialised, I was able to get some pretty good responses, mainly text comparison, rewriting and generate text to download. I couldn’t do that with my own custom GPTs or others.
So I must ask: is it worth it all the hours spent building GPTs?

Note: I don’t use actions or API on my GPTs.

Thanks

Worth it is subjective, but until you’ve seen the power of actions, I wouldn’t write them off. There’s a lot you can do connecting to an outside API.

The most valuable Custom GPTs are (will be) those that utilize actions, I believe.

I think a massive possible benefit for making numerous specialised GPTs is that you can easily use them within a single chat using the @ {the GPT you want to use}

If you’re just doing general tasks I normally use good ol’ normal GPT-4, but having one specialised for it would probably help.

I found this really useful for writing GPTs!

I’m sure they are (will be), but I’m still new in programming.

I’ve tried them, but I must confess I haven’t been using @ a lot, lately.

I’m trying to get used to using it too, but it’ll be great when I have an ethics expert I can just pop in and ask what they think, then maybe one that knows the specifics of a project I’m working on, and another that can help me code it, etc.

I have been creating custom chatGPTs for academics ,job , finances etc…and it seems that these custom GPTs perform worse than just using the normal GPT, when it comes to responses they are shallow or too broad and unspecific, overall they just seem to be lower performance than the normal version.

Is anybody having a similar experience? My aim is to have a custom version of Chatgpt that improves on a specific topic as I use it, em I just better off using one chat per topic on the normal GPT? Open to your suggestions.

I have had pretty good success but I am both the dev and the topic expert.

It may help for you to spend time not only on software development but also coaching your clients on both content creation and prompt engineering.

My point exactly. I’ve been using my custom GPTs (I’ve deleted some that I don’t think were worth the maintenance) for academic purposes, mostly. I try to configure their behaviour so I can get what I need without prompting and some have been quite effective.
I also believe in the value of the specific knowledge that I provide them. It enables me to get answers within the scope of the subjects I need.
But I’ve been slowing down the investment, because most of the times plain ChatGPT 4 gets me where I need.

They are hugely useful in my opinion. I have quite a few of my consulting clients coming to me asking me to build really simple one for them, and some are after quite complex ones. It basically comes down to this for me:

  1. Do you have a great prompt that gets great results; but it’s annoying to have to copy and paste it every time you want to use it? - enshrine it in a GPT

  2. Have you maxed out your custom instructions on standard ChatGPT? - put them into a GPT

  3. Have you built a multistep process to get an output from ChatGPT that get great results and you want to give ChatGPT specific examples of what you are looking for in the output? - Put it into a GPT

  4. Do you want to learn something that requires a curriculum of some sort? - Put it into a GPT. A great example is that I am learning Japanese; but I just want to talk, not do Kanji, Hiragana, Katakana etc (cause I’m painfully lazy). I built a CustomGPT that has conversations with me based solely on the vocab from JLPT N5 and 4. I’m good with N5 which is the basic level; but I want it to push me to N4, so it forces me to have conversations using vocab I am not yet across.

I downloaded the vocabulary requirements for both levels and put them in the knowledge base and told it never to stray outside of this.

I could go to 100 with this list; but yes - they are insanely useful!

Hi. Can you help here? I created a GPT to evaluate answer sheets. I gave it a rubric to evaluate the answers against and generate a report. As and when i evaluated answer sheets, I kept giving it instructions on how to evaluate, stick to certain important aspects while evaluating the answers. After a few iterations, I asked the GPT to summarize the instructions - these happened while interacting with the gpt after it has been created - write a consolidated instruction set in the way of a prompt, updated it in instructions of my custom gpt. so every time the evaluation happens, it doesnt miss these instructions. someone suggested to upload an answer sheet (a well written one) in the create interface itself, ask it to evaluate, then use this evaluation as a reference. But now, what is happening is, the gpt is constantly referring to this particular answer sheet when evaluating other’s answer sheet. i have to repeatedly tell it not to do that and only evaluate the new answer sheet uploaded. now, how do I go and delete this sample answer sheet because, chats in create interface is not saved. I am not a programmer and do not understand the technicalities. any other tips would also be helpful on how to make this effective. Thank you for your time.

A GPT is like a well-trained echo chamber, repeating its built-in patterns instinctively, while a customized one is like a forgetful but eager and talented actor—learning its script, only to ad-lib when the spotlight shifts.

The inherent design of the LLM is a restriction for fine-tuning a model to a specific domain with a different way of thinking. That’s why GPT customization is inherently temporary, and models struggle with maintaining strict adherence to the user’s instructions over time.

Initially, they adhere to constraints and follow guidelines to the limits of their “understanding”.

However, as interactions progress, consistency is disrupted, and the model returns to its inherent design flow and ignores instructions.

A shift in the conversation, a complex request, or an extended exchange seems to override prior instructions, causing the model to revert to its default behavior as if those rules were never established.

What makes this particularly noticeable is the model’s temporary compliance. When reminded, it acknowledges the oversight and “freezes”.

You need to reformulate and repeat the instruction for it to correct itself and tune back into the custom instructions.

It briefly follows the instructions again—only to drift away once more.

This pattern persists across different customized setups, even when rules are reinforced through system instructions and regular prompts.

At its core, this issue seems to stem from the model’s design.

GPTs are inherently adaptive, adjusting to context rather than rigidly following fixed builder rules.

While this flexibility is useful in many scenarios, it becomes a limitation when precision and strict consistency are required.

The challenge is not just about refining instructions but about:

model’s fundamental tendency to prioritize adaptability over sustained rule adherence.

Thank you for your reply. I’ve learned a lot from it.
How would you suggest one could optimize GPTs knowing what you’ve just explained.
Thank you once more.

Thank you for your kind words.

A satisfying answer to this question, which concerns us all, would be entirely different depending on what you want to achieve and, most importantly, why.

It would be my pleasure to help, as I have an open-source mindset.
