分析显示，GPT-5.6 的三个变体（Terra、Sol、Luna）中，Terra 在智能-成本曲线上全面落后。对于 Terra 的每个推理级别，买家都能找到 Luna 或 Sol 配置，以相同成本获得更高智能，或以更低成本获得相近智能。Luna 在成本敏感型工作负载中表现最突出，能以远低于高推理级别 Sol 和 Terra 的成本达到有竞争力的智能分数。当效率优先时，Luna 是最强的默认选择。
GPT 5.6 Terra is behind across the entire intelligence-cost curve.
i.e. Terra will never be justifiable on either price or performance.
Luna and Sol consistently dominate Terra. i.e. at every Terra reasoning level, buyers can choose a Luna or Sol configuration that delivers more intelligence for the same cost, or similar intelligence for less.
Luna stands out most for cost-sensitive workloads. It reaches competitive intelligence scores at a fraction of the cost of higher-effort Sol and Terra settings.
So looks like Luna is the strongest default choice when efficiency matters.
GPT-5.6 Sol and Luna are ahead of Terra at every point on the Intelligence vs Cost per Task chart. GPT-5.6 Luna stands out as a particularly cost efficient model Charting the Artificial Analysis Intelligence Index shows the trade-off between intelligence and Cost per Intelligence Index Task. Across reasoning efforts, each GPT-5.6 model pushes past GPT-5.5 on the Pareto frontier (excluding non-reasoning). However, Luna and Sol are always ahead of Terra. This means for any Terra effort level, there is a Luna or Sol effort level that is more intelligent at no extra cost, or as intelligent at lower cost.在 X 查看被引用的帖子
