OpenAI rolls out budget-priced mid-tier GPT-6.1 Terra

OpenAI has added a mid-range model to its GPT-6.1 family, offering strong performance at a lower price.

The AI business' general-purpose models span four tiers. Products named "Sol" or "Astra" are its high-end offerings and come with price tags to match. "Luna" models are its cheapest offerings. This new model gets the "Terra" treatment the company reserves for mid-range models.

"Terra continues to advance the cost-intelligence frontier across our model families, providing a new balance of speed, capability, and cost," OpenAI said. "Its standard API prices are 50 percent lower than those of GPT-5.6 Terra and GPT-6.1 Sol, making it practical for developers to automate high-volume work, like reading incoming invoices and entering their details into accounting software."

Artificial Analysis, a site that tracks model performance and cost, notes that GPT-6.1 Terra pushes the cost efficiency frontier. "It is the first Terra-class model since GPT-5.6, and is more intelligent for less than a third of the cost," the site says. …
