OpenAI releases powerful AI known as GPT-4

The startup OpenAI yesterday said it is beginning to release a powerful artificial intelligence model known as GPT-4, setting the stage for human-like technology to proliferate and more competition between its backer Microsoft Corp and Alphabet Inc’s Google.OpenAI, which created the chatbot sensation ChatGPT, said that its latest technology is "multimodal,” meaning images as well as text prompts can spur it to generate content. The text-input feature will be available to ChatGPT Plus subscribers and to software developers, with a waitlist, while the image-input ability remains a preview of its research.The highly-anticipated launch signals how office workers may turn to ever-improving AI for still more tasks, as well as how technology companies are locked in competition to win business from such advances.Alphabet Inc’s Google yesterday announced a "magic wand” for its collaboration software that can draft virtually any document, days before Microsoft is expected to showcase AI for its competing Word processor, likely powered by OpenAI.The startup’s latest technology in some cases represented a vast improvement on its prior version known as GPT-3.5, it said. In a simulation of the bar exam required of US law school graduates before professional practice, the new model scored around the top 10% of test takers, versus the older model ranking around the bottom 10%, OpenAI said.While the two versions can appear similar in casual conversation, "the difference comes out when the complexity of the task reaches a sufficient threshold,” OpenAI said, noting "GPT-4 is more reliable, creative, and able to handle much more nuanced instructions.”
