Openai is gradually addressing all the concerns around the GPT-5, including the rate limit and now its personality, which has been criticized for being less positive.
One in Assistant documentOpenai confirmed that it has restored old models for paid customers, so now you can use GPT4O, GPT O3, and more.
You simply need to use the model selector and choose one of the models under the heritage model.
In addition, GPT-5 automatically switchs between sharp and thinking, and you can also choose additional GPT-5 options directly from the top of the model picker. For example, we now have GPT-5 fast, which provides immediate answers.

Then, there is thinking, which provides deep argument. The GPT-5 thinking mini provides rapid argument, and there is also Pro, which Openai states that there is research-grade intelligence.
The GPT-5 thinking limit has been reduced to 3,000 per week for GPT Plus customers, but it is not all.
One in Post At X, Openai CEO Sam Altman confirmed that it was working on the update of GPT-5’s personality.
Once the update is rolled out, the GPT-5 will feel warm compared to the current version, but it does not expect that it will be ‘positive’ as GPT-4O.
Openai is also searching for the model personality-use optimization of personality.
