March 14 was a significant day for the AI community, with OpenAI releasing GPT-4, a multi-modal language model that combines text and image capabilities. GPT-4 has a longer context length than its predecessor, allowing it to process hundreds of pages in a single prompt. The model demonstrates impressive behavior such as visual question answering and image captioning. Its training dataset is likely similar to that of KOSMOS-1, which also uses pre-trained image encoders and multimodal inputs. GPT-4 has been fine-tuned using Reinforcement Learning from Human Feedback (RLHF) to align its output with user intent. The model's capabilities include text-only and text-vision tasks, with the latter demonstrating impressive visual reasoning abilities. As future models are trained on additional modalities like audio and video, they may possess even more advanced capabilities, such as generating art or music from text prompts. However, this growth in capabilities also raises concerns about AI safety, particularly "intent alignment," which requires careful consideration to ensure that systems optimize for intended goals rather than unintended ones. Overall, GPT-4 represents a significant step forward in multi-modal language modeling and highlights the need for continued research into AI safety and ethics.
