OpenAI bets on AI economics with lower-cost GPT-6.1 Terra

OpenAI has introduced GPT-6.1 Terra, a new reasoning model that offers near-frontier performance on visual reasoning, professional task execution, and computer-use benchmarks at a lower cost compared to its predecessors. This mid-tier model is designed to cater to organizations seeking better accuracy and automation capabilities for large-scale operational workloads, promising a 50% lower price compared to GPT-5.6 Terra.

Aimed at developers and enterprises, GPT-6.1 Terra is positioned between GPT-6 Luna and higher-capability models GPT-6.1 Sol and GPT-6 Astra. Delivering impressive results, GPT-6.1 Terra scored 60.0% on Agents' Last Exam, a benchmark of professional tasks, while costing only $1.01 per task. This outperforms GPT-5.6 Terra at $3.58 per task, GPT-6.1 Sol at $2.00 per task, and GPT-6 Astra at $7.24 per task.

In visual reasoning, GPT-6.1 Terra surpassed its predecessor GPT-5.6 Terra while nearly matching top-tier frontier models such as GPT-6 Astra and GPT-6.1 Sol, all at a fraction of the cost.
