GPT-4 is OpenAI’s most advanced system, producing safer and more useful responses  

Human decision-making shows systematic simplifications and deviations from the tenets of rationality (‘heuristics’) that may lead to suboptimal decisional outcomes (‘cognitive biases’).   There are currently three prevailing theoretical perspectives on the origin of heuristics and cognitive biases: a cognitive-psychological an ecological an evolutionary perspective However, these perspectives are mainly descriptive and none of them provides an overall explanatory framework for the underlying mechanisms of cognitive biases.   To enhance our understanding of cognitive heuristics and biases we propose a neural network framework for cognitive biases, which explains why our brain systematically tends to default to heuristic (‘Type 1’) decision...

In 1997, IBM’s Deep Blue defeated the reigning world champion chess player, Garry Kasparov. In 2016, Google’s AlphaGo defeated one of the worlds top Go players in a five-game match. Today, OpenAI released GPT-4, which it claims beats 90% of humans who take the bar to become a lawyer, and 99% of students who compete in the Biology Olympiad, an international competition that tests the knowledge and skills of high school students in the field of biology. In fact, it scores in the top ranks for at least 34 different tests of ability in fields as diverse as macroeconomics, writing,...

When Microsoft announced the new AI-enabled Bing, which it built on top of OpenAI’s GPT models, neither company would confirm which version of GPT was being used beyond saying it was a next-gen version of the model that powered ChatGPT. Today, OpenAI announced GPT-4, a significant update to GPT-3.5. As it turns out, Bing was using it all along. “We are happy to confirm that the new Bing is running on GPT-4, which we’ve customized for search,” Microsoft’s Yusuf Mehdi, the company’s corporate VP and consumer chief marketing officer, wrote in today’s announcement. “If you’ve used the new Bing preview at any time in...

OpenAI has released a powerful new image- and text-understanding AI model, GPT-4, that the company calls “the latest milestone in its effort in scaling up deep learning.” GPT-4 is available today to OpenAI’s paying users via ChatGPT Plus (with a usage cap), and developers can sign up on a waitlist to access the API. Pricing is $0.03 per 1,000 “prompt” tokens (about 750 words) and $0.06 per 1,000 “completion” tokens (again, about 750 words). Tokens represent raw text; for example, the word “fantastic” would be split into the tokens “fan,” “tas” and “tic.” Prompt tokens are the parts of words fed into GPT-4 while completion tokens...
