Usage limit for custom GPT?

GPT builders
1

I’m creating a custom GPT for students in my class. I have a plus account, they don’t. A student told me that they were cut off from using the custom GPT after only 10 messages. I don’t see any way of changing which model the custom GPT is using, or of extending the number of messages that users can use. Is there any way to allow them to have more than 10 interactions?

I prefer the idea of a custom GPT, where I’ve provided instructions and reference material, to having the each student do that in at the beginning of their conversation with ChatGPT. But if there is another option I’m missing please let me know.

Thanks!

Welcome to the dev forum!

I don’t believe you can set it, but if you have some features like DALL·E Image Generation or Code Interpreter & Data Analysis, it might be only available on the newer models, so it can’t downgrade.

You might try making just a basic one and see if you can get more than 10 messages from it…

Please let us know…

ETA: It looks like 3.5 isn’t available in ChatGPT anymore …

  • GPT-4o mini

  • Our lightest-weight intelligence model.

  • 128k context length (i.e. an average to longer novel).

  • Text and image input / text and image output.*

  • Audio input / output.**

  • Limitation: This model does not have access to the advanced tools that GPT-4o has.

@ehudson Did you find a solution?
I have the exact same issue, I also want to send a lot more traffic to my custom gpt but there isn’t much point because of the message cap.
I looked at using the API path but I’m certain it would increase latency which would be the death of my app.

Hi,

Unfortunately, no really good one. I ended up pasting the text that I had in the custom GPT definition onto a Canvas page for my students to copy. There were parts of it that I really would rather the students didn’t see, so I made that text hidden:

Text here is hidden

Then I surrounded it with non hidden text so that students copying and pasting without actually reading what they pasted (given that its a lot of text I imagine that is all students) wouldn’t see the “hidden instructions.”

Definitely not as elegant as having a custom GPT but it does work in that they can use it as many times as they like without paying. I encourage the students to open chatGPT in incognito mode in which case they have infinite messages (they are asked to log in occasionally, but can just ignore those requests).,

Take care,
Eric
