About GPT-4

GPT-4, developed by OpenAI and launched on March 14, 2023, is a multimodal large language model representing the fourth iteration of the GPT series. It significantly enhances its predecessors' capabilities by processing both text and image inputs, enabling it to describe visual content, summarize screenshots, and answer questions involving diagrams1. GPT-4 demonstrates improved reliability, creativity, and nuanced instruction handling compared to GPT-3.5, with context windows expanded to 8,192 and 32,768 tokens1. The model's transformer architecture leverages attention mechanisms for advanced language understanding and context retention5. GPT-4 also exhibits greater steerability, allowing users to influence its tone and style more precisely, and has improved safety measures to minimize harmful or biased outputs
