OpenAI GPT Models

OpenAI’s GPT family provides general-purpose foundation models for text, vision, coding, tool use, structured outputs, and agentic workflows. The current GPT‑5.6 generation includes Sol for the hardest professional and scientific work, Terra for balanced everyday use, and Luna for efficient high-volume tasks. Developers can access the models through OpenAI’s APIs, while the same family powers experiences across ChatGPT and Codex. The lineup supports configurable reasoning effort, computer use, multimodal inputs, and long-running workflows.
