Terra is one of the GPT-5.6 model variants released as part of OpenAI’s broader launch alongside Luna and Sol. Recent coverage describes it as a lower-cost option within GPT-5.6 for enterprise and developer use, and notes that OpenAI cut Terra’s API pricing by 20% to $2 per million input tokens and $12 per million output tokens after launch. Coverage also links the pricing changes to infrastructure-related improvements and a wider move toward more cost-efficient deployment.
