According to references on OpenAI’s website, the Microsoft-backed AI startup plans to launch five new models this week, including GPT-4.1, 4.1 nano, and 4.1 mini.
BleepingComputer previously reported that OpenAI is working on three new AI models called o4-mini, o4-mini-high and o3.
While it’s unclear when the reasoning model o4-mini-high is coming or if the plans have changed, OpenAI is now working on GPT-4.1, 4.1 nano, and 4.1 mini.
This is according to the updated model art and icons for the model pages on OpenAI’s website.
As shown in the above screenshot, in the last few hours, OpenAI has added icons for the o3, o4-mini, GPT-4.1, 4.1 nano, and 4.1 mini. models ahead of the launch.
These five models might arrive as soon as this week, but this naming convention will be a tad confusing for users.
o4-mini and 4.1-mini sound too similar, but they serve different purposes. While o4 is a reasoning model, 4.1 is expected to be a successor to the multimodal GPT-4.
At this point, one thing is clear: OpenAI has no plans to launch GPT 5 anytime soon.
In addition to new models, my sources tell me that OpenAI is planning to release 4o imagegen model API in some limited form, but it’s unclear if the API will be rolled out this week or next week.
