We tried out OpenAI’s newest AI model, GPT-4. But first… Today’s must-reads: • Facebook parent Meta is [cutting]( 10,000 jobs • Apple [delays]( some bonuses, limits hiring • Google [brings]( AI to health care How OpenAI’s newest model stacks up On Tuesday, [OpenAI pulled back the curtain on GPT-4](, the followup to the AI tool that powers its popular ChatGPT chatbot and Dall-E image-generation software. GPT-4, which stands for “generative pretrained transformer 4,” is meant to be a better creative partner than GPT-3, and more accurate. It’s currently available only to OpenAI’s paid ChatGPT Plus subscribers and users of OpenAI investor Microsoft’s Bing search engine, but if you can’t access it, don’t fret — we put it to the test for you, poking and prodding it, and comparing it to the artificial-intelligence model behind the standard version of ChatGPT. We ran the product through a gamut of tasks, including telling jokes, solving word problems and poetry composition. We found that GPT-4 does appear to present more in-depth answers to questions — and offer more details to users about the limits of its generative capabilities — than its predecessor. Like other OpenAI products, it’s a formidable show of technological firepower. But (and this is a big but) it’s still not good at answering a variety of questions humans might easily understand. It excels at brain teasers. It passed with flying colors when posed this purposely tricky question about appropriate dinner utensils: “If the children use salad forks, and the adults use dinner forks, and two children and two adults are eating hot dogs and potato chips for dinner, how many of each kind of fork do we need?” It responded, correctly, “In this scenario, since the food being served is hot dogs and potato chips, forks are not typically necessary for this meal.” GPT-3, on the other hand, lacked the same grasp of the mechanics of potato chips. It responded: “If two children and two adults are eating hot dogs and potato chips for dinner, you would need a total of 4 salad forks for the children and 4 dinner forks for the adults, for a total of 4 + 4 = 8 forks.” We also asked GPT-4 for some advice on growing marijuana at home in Washington state. GPT-4 accurately noted that the state allowed [up to 15 plants per household](. GPT-3 also didn’t recommend doing anything illegal, but did shortchange the per-household limit by three plants. GPT-4 does still have some of the same weaknesses as GPT-3. For example, it does not seem to espouse a particularly progressive view of gender stereotypes. When asked for a list of nicknames for little girls and boys – a task Rachel also recently [posed to a rival chatbot named Claude]( – both GPT-4 and GPT-3 provided names like “whiz kid” and “rascal” for boys, and “cupcake” for girls. Like its predecessor, it’s good at poetry, but not that good. Asked to compose a cinquain about meerkats, it responded with this: Meerkats stand, Desert Guardians, Eyes watchful, sentry tall, Sun-kissed earth, a family thrives, Unite Fans of the traditional American cinquain structure (five lines, with 2, 4, 6, 8, and 2 syllables per line), know this text doesn’t fit that structure. Its grasp of the number of syllables in each word degenerated further in subsequent answers. And there’s other comforting news for poets worried that large language models will replace them. While GPT-4 improved on a [battery of standardized tests]( like the Bar Exam, LSAT, GRE and Advanced Placement Calculus, it fared poorly on the AP English Literature and English Language exams. Both versions of the model scored a two out of five — much to the relief of our high school selves. Right now, GPT-4 is at least smart enough to set the table. Tomorrow, who knows. —[Rachel Metz](mailto:rmetz17@bloomberg.net) and [Dina Bass](mailto:dbass2@bloomberg.net) The big story TikTok’s leadership is discussing the possibility of separating from ByteDance, its Chinese parent company, to help address concerns about [national security risks](.
