ChatGPT has had the robotic equivalent of a makeover – but experts aren’t exactly impressed.

OpenAI unveiled a new flagship artificial intelligence (AI) model, GPT-5, yesterday.

The upgrade is available to all 700million users for free, though paid subscribers have fewer usage limits.

‘Our smartest, fastest, most useful model yet, with built-in thinking that puts expert-level intelligence in everyone’s hands,’ the start-up said.

What new features are there?

The virtual assistant is now powered by a so-called reasoning model, which spends more time ‘thinking’ through a problem.

OpenAI says the bot is far faster than before, is better at coding and is now more customizable.

Users can change the chat colours and choose from preset ‘personalities’, like ‘cynic’, ‘listener’, and ‘robot’.
