ChatGPT maker's AI model GPT-4 is capable of ‘human-level performance’. What can it do?

The company behind the ChatGPT chatbot has rolled out its latest artificial intelligence model, GPT-4, in the next step for a technology that’s caught the world's attention. OpenAI says GPT-4 “exhibits human-level performance.” It's much more reliable, creative and can handle “more nuanced instructions" than its predecessor system, GPT-3.5, which ChatGPT was built on, OpenAI said in its announcement. “With GPT-4, we are one step closer to life imitating art,” said Mirella Lapata, professor of natural language processing at the University of Edinburgh. In one example posted on OpenAI's website, GPT-4 is asked, “What is unusual about this image?” It's answer: “The unusual thing about this image is that a man is ironing clothes on an ironing board attached to the roof of a moving taxi.” GPT-4 is also “steerable,” which means that instead of getting an answer in ChatGPT's “classic” fixed tone and verbosity, users can customize it by asking for responses in the style of a Shakespearean pirate, for instance. OpenAI says GPT-4's improved capabilities “lead to new risk surfaces" so it has improved safety by training it to refuse requests for sensitive or “disallowed” information.
