Custom GPTs - usage for free tier

Hi, I would like to ask what model users on the free tier would get access to if I set a specific model for use in my custom GPT. For instance, if I set 5.4 Thinking currently, it won’t work on the free tier, and even with 5.3, there would be restrictions after some usage. There are options to set older models like 5.2 Thinking or 5 Mini Thinking, but are these thinking models available for use on the free trial? I want to collect some data about the GPT, and I’m afraid that if every user is getting a different model to use, it will result in contradictory feedback. Would appreciate your input, thanks!

Hi Kavya — thanks for raising this question around Custom GPT model availability for Free users.

Model availability and usage limits can change over time, so if you’re still testing your GPT, please refer to the current ChatGPT plan/model availability and test with the model configuration you intend to support. If you’re seeing inconsistent behavior for Free users today, please start a new topic with the current model selected and what those users are experiencing.

Since this topic has been inactive for some time, we’re closing it now. Thanks for being part of the community.
