OpenAI shipped GPT-4 yesterday, the much-anticipated text-generating AI model, and it’s a curious piece of work.

GPT-4 improves upon its predecessor, GPT-3, in key ways, for example giving more factually true statements and allowing developers to prescribe its style and behavior more easily. It’s also multimodal in the sense that it can understand images, allowing it to caption and even explain in detail the contents of a photo.
