This 2023 paper, GPT-4 Technical Report from OpenAI introduces GPT-4, a multimodal AI model capable of processing both image and text inputs to produce text outputs, demonstrating human-level performance on various professional and academic benchmarks, such as the bar exam. The report highlights the predictable scaling of the model's performance and its improved factual accuracy and adherence to desired behaviors achieved through post-training alignment processes like Reinforcement Learning from Human Feedback (RLHF). It also addresses the model's limitations, including "hallucinations" and potential for misuse, detailing the safety evaluations and mitigation strategies implemented to reduce harmful outputs.
