OpenAI GPT-5 launch live – all the latest news as new models leak, plus how to watch the livestream

It's the one we've all been waiting for – ChatGPT-5 is will be released in the next few hours! Earlier in the week OpenAI CEO Sam Altman teased that "something big" was coming on Friday, but then today the OpenAI account on X.com tweeted: "LIVE5TREAM THURSDAY 10AM PT".

Notice the use of a 5 instead of an "S" in the word "LIVE5TREAM"? That can mean only one thing: ChatGPT-5 is coming!

With a livestream kicking off at 10AM PT, 1PM ET, and 6PM BST, we'll embed the watch link as soon as it's live below, and TechRadar will bring you the news as it breaks.

So what can we expect? Well, the speculation is that ChatGPT-5 models (the names of a few of which have already been leaked) will be leaps and bounds ahead of the ChatGPT-4 models that we currently use in terms of performance.

What we don't know yet is which of the various OpenAI subscription offerings will get access to the new ChatGPT-5 models first, and will it be available to free users as well? We'll keep you up to date with the latest news as it breaks here.
