ChatGPT Changed Everything. Now Its Follow-Up Is Here.

Less than four months after releasing ChatGPT, the text-generating AI that seems to have pushed us into a science-fictional age of technology, OpenAI has unveiled a new product called GPT-4. Rumors and hype about this program have circulated for more than a year: Pundits have said that it would be unfathomably powerful, writing 60,000-word books from single prompts and producing videos out of whole cloth. Today's announcement suggests that GPT-4's abilities, while impressive, are more modest: It performs better than the previous model on standardized tests and other benchmarks, works across dozens of languages, and can take images as input--meaning that it's able, for instance, to describe the contents of a photo or a chart. Unlike ChatGPT, this new model is not currently available for public testing (although you can apply or pay for access), so the obtainable information comes from OpenAI's blog post, and from a New York Times story based on a demonstration. From what we know, relative to other programs, GPT-4 appears to have added 150 points to its SAT score, now a 1410 out of 1600, and jumped from the bottom to the top 10 percent of performers on a simulated bar exam.
