GPT-4 Meaning

GPT-4 (Generative Pre-trained Transformer 4) is OpenAI’s fourth-generation large language model that demonstrates advanced reasoning, multimodal capabilities, and enhanced safety compared to its predecessors. This transformer-based architecture processes both text and images, enabling complex problem-solving across diverse domains including mathematics, coding, creative writing, and visual analysis. GPT-4 employs constitutional AI training methods and reinforcement learning from human feedback (RLHF) to improve alignment and reduce harmful outputs. The model features an expanded context window, supporting longer conversations and document analysis. Key improvements include better factual accuracy, reduced hallucinations, and enhanced instruction-following capabilities. GPT-4 powers various applications through API access, enabling integration into AI agents, chatbots, and automated workflows. For agentic systems, GPT-4 serves as a reasoning engine capable of multi-step planning, tool usage, and complex decision-making, making it foundational for sophisticated AI agent implementations.
