Hot on the heels of Google's Workspace AI announcement Tuesday, and ahead of Thursday's Microsoft Future of Work event, OpenAI has released the latest iteration of its generative pre-trained transformer system, GPT-4. Whereas the current generation GPT-3.5, which powers OpenAI's wildly popular ChatGPT conversational bot, can only read and respond with text, the new and improved GPT-4 will be able to generate text on input images as well. "While less capable than humans in many real-world scenarios," the OpenAI team wrote Tuesday, it "exhibits human-level performance on various professional and academic benchmarks."
