The launch of GPT-4.1 is expected as soon as next week, alongside smaller variants like the GPT-4.1 mini and nano.

Both the o3 and o4 mini models are also expected to launch next week, pending any changes to OpenAI's plans.

The GPT-4o model, first introduced last year, integrates capabilities across text, image, and audio in real time, setting a high bar for the new releases.

In a recent statement, Altman hinted at an exciting feature launch on X, although it remains uncertain whether this is related to the upcoming models.

OpenAI is gearing up to release a new suite of AI models, including the highly anticipated GPT-4.1, which is an upgraded version of the multimodal GPT-4o model.

AI engineer Tibor Blaho has discovered references to the o4 mini, o4 mini high, and o3 models in a new version of ChatGPT, suggesting that these releases are imminent.

In addition to GPT-4.1, OpenAI is preparing to unveil the full version of its o3 reasoning model and an o4 mini version, which may debut even sooner.

However, OpenAI has faced delays in introducing these new models due to capacity issues, which could impact the launch timeline for GPT-4.1.

CEO Sam Altman has advised customers to anticipate potential delays and service disruptions as the company works to address these capacity challenges.
