OpenAI is engaged on one more AI mannequin reportedly known as GPT-4.1, a successor to GPT-4o, which is predicted to come earlier than GPT 5.0
The Verge lately reported that OpenAI plans to launch GPT-4.1, which is an improve to the prevailing GPT-4o. And now, we now have extra causes to imagine the mannequin is certainly coming.
As noticed by AI researcher Tibor Blaho, OpenAI is already testing mannequin artwork for o3, o4-mini, and GPT-4.1 (together with nano and mini variants) on the OpenAI API platform.

This confirms that GPT-4.1 does exist, however it would not seem like a successor to GPT-4.5.
My understanding is that GPT-4.1 is a successor to GPT-4o, which is multimodal. Alternatively, GPT-4.5 focuses extra on creativity and delivering higher solutions.
In a “Pre-Coaching GPT-4.5” video from OpenAI, founder and CEO Sam Altman dropped hints that OpenAI has a group that desires to redo GPT-4 from scratch utilizing new coaching information and techniques.
“In case you guys may go decide whoever you needed, what’s the smallest group from OpenAI that would go retrain GPT-4 from scratch as we speak with the whole lot we all know and have and all of the techniques work?” Sam stated.
It is unclear if Altman is referring to the brand new GPT-4.1 mannequin, but when I have been to guess, I would guess on GPT-4.1.
Additionally, GPT-5 is not occurring anytime quickly, as OpenAI plans to concentrate on o3, o4-mini, o4-mini-high, and GPT-4.1 (together with nano and mini variants).
