GPT-4 was launched by OpenAI on March 14, 2023. “GPT-4 is a large multimodal model (accepting image and text inputs, emitting text outputs) that, while less capable than humans in many real-world scenarios, exhibits human-level performance on various professional and academic benchmarks.” (Website OpenAI) On its website, the company explains the multimodal options in more detail: “GPT-4 can accept a prompt of text and images, which – parallel to the text-only setting – lets the user specify any vision or language task. Specifically, it generates text outputs (natural language, code, etc.) given inputs consisting of interspersed text and images.” (Website OpenAI) The example that OpenAI gives is impressive. An image with multiple panels was uploaded. The prompt is: “What is funny about this image? Describe it panel by panel”. This is exactly what GPT-4 does and then comes to the conclusion: “The humor in this image comes from the absurdity of plugging a large, outdated VGA connector into a small, modern smartphone charging port.” (Website OpenAI) The technical report is available via cdn.openai.com/papers/gpt-4.pdf.
