With its uncanny ability to hold a conversation, answer questions, and write coherent prose, poetry, and code, the chatbot ChatGPT has forced many people to rethink the potential of artificial intelligence.
The new algorithm, called GPT-4, follows GPT-3, a groundbreaking text-generation model that OpenAI announced in 2020, which was later adapted to create ChatGPT last year. The new model scores more highly on a range of tests designed to measure intelligence and knowledge in humans and machines, OpenAI says. It also makes fewer blunders and can respond to images as well as text.
However, GPT-4 suffers from the same problems that have bedeviled ChatGPT and cause some AI experts to be skeptical of its usefulness—including tendencies to “hallucinate” incorrect information, exhibit problematic social biases, and misbehave or assume disturbing personas when given an “adversarial” prompt.
“While they’ve made a lot of progress, it’s clearly not trustworthy,” says Oren Etzioni, a professor emeritus at the University of Washington and the founding CEO of the Allen Institute for AI. “It’s going to be a long time before you want any GPT to run your nuclear power plant.”
