Terra also performs similarly to GPT-6.1 Sol while operating at roughly half the price, according to Android Authority. That places Terra as a lower-cost option in OpenAI's 6.1 lineup rather than the top-performance model.

The release comes nearly a month after OpenAI introduced GPT-6.1 Sol, the report said. Terra is the next model to cross the 6.1 threshold, following GPT-5.6 Terra, which launched this past summer. Android Authority reported that the new model promises large performance and efficiency gains.

Astra remains OpenAI's performance king, according to the report. Terra's appeal rests on nearing the output quality of more expensive models while costing less, the report said.

OpenAI has released GPT-6.1 Terra, which Android Authority reports offers output quality close to GPT-6.1 Sol at roughly half the cost, while Astra remains the performance leader. Terra follows GPT-5.6 Terra and marks OpenAI's next 6.1-series model.
