GPT-6.1 Terra 发布：API 价格减半，性能仍逼近更大模型
原标题：GPT-6.1 Terra halves OpenAI's API prices and still gains ground on its larger models
AI 摘要
OpenAI 发布中端模型 GPT-6.1 Terra，API 价格仅为前代 GPT-5.6 Terra 的一半，输入每百万 token 1 美元、输出 5 美元，主打办公任务与自动化软件控制。Artificial Analysis 称其刷新了「每美元智能」基准，在智能指数上比前代高 6 分而单任务成本不到三分之一，并显著降低幻觉率。该模型达到 OpenAI 预备框架的「关键」网络安全阈值，已向 ChatGPT 付费用户和 API 开放。
