Leak confirms OpenAI’s GPT 4.1 is coming before GPT 5.0
OpenAI is working on yet another AI model, reportedly called GPT-4.1, a successor to GPT-4o.
The Verge recently reported that OpenAI plans to launch GPT-4.1, which is an upgrade to the existing GPT-4o. And now, we have more reasons to believe the model is indeed coming.
As spotted by AI researcher Tibor Blaho, OpenAI is already testing model art for o3, o4-mini, and GPT-4.1 (including nano and mini variants) on the OpenAI API platform.
This confirms that GPT-4.1 does exist, but it doesn’t appear to be a successor to GPT-4.5.
My understanding is that GPT-4.1 is a successor to GPT-4o, which is multimodal. On the other hand, GPT-4.5 focuses more on creativity and delivering better answers.
In a “Pre-Training GPT-4.5” video from OpenAI, founder and CEO Sam Altman dropped hints that OpenAI has a team that wants to redo GPT-4 from scratch using new training data and systems.
“If you guys could go pick whoever you wanted, what is the smallest team from OpenAI that could go retrain GPT-4 from scratch today with everything we know and have and all the systems work?” Sam said.
It’s unclear if Altman is referring to the new GPT-4.1 model, but if I were to bet, I’d bet on GPT-4.1.
Also, GPT-5 isn’t happening anytime soon, as OpenAI plans to focus on o3, o4-mini, o4-mini-high, and GPT-4.1 (including nano and mini variants).
