GPT4
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 was aligned with reinforcement learning from human feedback (RLHF) and, for safety-relevant prompts, a rule-based reward model, which reduced disallowed outputs compared with the base model.
