OpenAI GPT models

OpenAI's Generative Pre-trained Transformer models: the industry standard for advanced AI reasoning, code generation, and multimodal task execution.

The GPT model series (Generative Pre-trained Transformer) represents a family of large, powerful AI models, fundamentally changing natural language processing. Flagship versions, like GPT-5.2, excel at complex problem-solving, offering sophisticated reasoning efforts for technical and scientific tasks. These models are multimodal, processing and generating text, image, and audio content. Developers leverage the API to integrate capabilities—from high-accuracy coding assistance to large-scale content generation—with specific versions optimized for speed (e.g., GPT-5 nano) or deep reasoning (e.g., GPT-5.2 pro).
