Greetings. It promises to be (another) massive week in A.I. news. And that’s leaving aside the lingering effects that the collapse of Silicon Valley Bank may have on some A.I. startups and the venture funds backing them.
Right as this newsletter was going to press, OpenAI released its long-anticipated GPT-4 model. The new model is multimodal, accepting both images and text as inputs, although it only generates text as its output. According to data released by OpenAI, GPT-4 performs much better than GPT-3.5, its latest model, and the one that powers ChatGPT, on a whole range of benchmark tests, including a battery of different tests designed for humans. For instance, GPT-4 scores well enough to be within the top 10% of test takers on a simulated bar exam. OpenAI also says that GPT-4 is safer than GPT-3.5—returning more factual answers and it's much more difficult to get GPT-4 to jump its guardrails than has been the case with GPT-3.5.
