Starting this afternoon, all existing OpenAI API developers “with a history of successful payments” can access GPT-4. GPT-4 can generate text (including code) and accept image and text inputs – an improvement over GPT-3.5, its predecessor, which only accepted text – and performs at “human level” on various professional and academic benchmarks. Like previous GPT models from OpenAI, GPT-4 was trained using publicly available data, including from public web pages, as well as data that OpenAI licensed.
If only OpenAI was actually open and released the model in its entirety.
