OpenAI is having a big week. Yesterday, the leading AI firm dropped not one, but two open-weight models, including one that can run well on Apple silicon Macs. Next? GPT-5 is coming to ChatGPT.
OpenAI’s teaser comes in the form of an X post that simply reads “LIVE5TREAM THURSDAY 10AM PT.”
You’ll notice that the ‘S’ in LIVESTREAM has been replaced with a 5, removing all doubt about what the next OpenAI livestream will be about.

ChatGPT took the world by storm in November 2022 when it launched with GPT-3.5. A few months later, OpenAI replaced it with GPT-4 in March 2023.
Since then, OpenAI has released a lot of new models, including GPT-4o, GPT-4.5, GPT-4.1 (which came after 4.5), and o4-mini. However, nothing has been worthy of the GPT-5 upgrade title.
It looks like that will change tomorrow when OpenAI shares details about what exactly GPT-5 can do. Stay tuned for news on Thursday at 10 am PT/1 pm ET.
Earlier this year, OpenAI’s Sam Altman previewed some details about how ChatGPT will work once GPT-5 arrives. A few things include showing chain-of-thought to reveal what ChatGPT is doing when it’s “thinking”, unifying the o-series model family within the GPT-model family, and generally integrating a lot of features from different models into a single model.
More recently, Altman teased his recent use of ChatGPT running GPT-5 in a casual reply to a social media post about TV show recommendations.
Separately, OpenAI updated how ChatGPT works on Monday in an effort to encourage healthier use (and avoid problematic headlines).
