OpenAI is working on yet another AI model reportedly called GPT-4.1, a successor to GPT-4o, which is expected to come before GPT 5.0[The Verge](https://www.theverge.com/news/646458/openai-gpt-4-1-ai-model) 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](https://x.com/btibor91/status/1910632880197558713)by AI researcher Tibor Blaho, OpenAI is already [testing](https://web.archive.org/web/20250411091731/https://cdn.openai.com/API/docs/images/model-page/model-art/gpt-4.1-mini.jpg) model art for o3, o4-mini, and GPT-4.1 (including nano and mini variants) on the OpenAI API platform.  **GPT 4.1 references on OpenAI’s website**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](https://www.youtube.com/watch?v=6nJZopACRuQ)’ 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](https://www.bleepingcomputer.com/news/artificial-intelligence/chatgpts-o4-mini-o4-mini-high-and-o3-spotted-ahead-of-release/), and GPT-4.1 (including nano and mini variants).
