What is GPT-4

GPT-4 is a large multimodal language model developed by OpenAI that represents a significant advancement in artificial intelligence capabilities, featuring enhanced reasoning, creativity, and reliability compared to its predecessors. This fourth-generation Generative Pre-trained Transformer processes both text and image inputs while generating human-like text responses, making it capable of understanding visual content, analyzing documents, and performing complex reasoning tasks across multiple modalities. GPT-4 demonstrates improved performance on professional and academic benchmarks, including bar exams, SATs, and advanced placement tests, while exhibiting better factual accuracy and reduced hallucinations. The model features a larger context window allowing it to process longer documents and maintain coherent conversations over extended interactions. Enterprise applications leverage GPT-4 for content creation, code generation, data analysis, customer support automation, and decision support systems where advanced reasoning and nuanced understanding are required. GPT-4’s architecture incorporates reinforcement learning from human feedback (RLHF) and constitutional AI techniques to improve alignment with human values and reduce harmful outputs, making it more suitable for production deployments in business-critical applications requiring reliable, safe AI assistance.
