Passage 2: Questions 26-30 In June 2020, a new and powerful artificial intelligence (AI) began __(26)__ technologists in Silicon Valley. Called GPT-3 and created by the research firm OpenAI in San Francisco, California, it was the latest and most powerful in a series of 'large language models': AIs that generate fluent streams of text after __(27)__ billions of words from books, articles and websites. GPT-3 had been trained on around 200 billion words, at an estimated cost of tens of millions of dollars. The developers who were invited to try out GPT-3 were astonished. "I have to say I'm blown away," wrote Arram Sabeti, founder of a technology __(28)__ who is based in Silicon Valley. "It's far more coherent than any AI language system I've ever tried. All you have to do is write a prompt and it'll add text it thinks would plausibly follow. I've gotten it to write songs, stories, press releases, guitar tabs, interviews, essays, technical manuals. It's hilarious and frightening. I feel like I've seen the future." OpenAI's team reported that GPT-3 was so good that people found it hard to distinguish its news stories from prose written by humans. It could also answer trivia questions, correct grammar, solve mathematics problems and even generate computer code if users told it to perform a __(29)__ task. Other AIs could do these things, too, but only after being __(30)__ trained for each job. 26.
