OpenAI released GPT-6.1 Terra as a mid-tier AI model balancing speed, capability, and cost

Systems trained on data to learn patterns and make predictions or generate outputs, such as text, images, or decisions, by approximating relationships between inputs and outputs without being explicitly programmed for each task.

OpenAI's fast, efficient GPT-6 series model for visual reasoning and computer use, released on October 26, 2026 at $1 per million input tokens and $5 per million output tokens, half the price of GPT-5.6 Terra and GPT-6.1 Sol.
