GPT4 meaning

GPT4 meaning refers to Generative Pre-trained Transformer 4, OpenAI’s fourth-generation large language model that demonstrates advanced reasoning, multimodal capabilities, and enhanced safety compared to predecessors. This transformer-based architecture processes both text and images, enabling complex problem-solving across mathematics, coding, creative writing, and visual analysis. GPT-4 employs constitutional AI training and reinforcement learning from human feedback (RLHF) to improve alignment and reduce harmful outputs. Key improvements include expanded context windows, better factual accuracy, reduced hallucinations, and enhanced instruction-following capabilities. The model 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.
