AI 导读
OpenAI 发布 GPT-6.1 Sol，以 GPT-6 Astra 五分之一的价格提供接近后者的智能水平，在所有推理设置下错误率与 GPT-6 Astra 相差不超过 1.9%。该模型在困难提示下提升了事实准确率，相比 GPT-6 Sol 提升最明显的是低推理强度场景，含事实错误的回答占比从 11.4% 降至 7.7%。原本预计今日发布的 GPT-6.1 Astra 并未推出。
推荐理由
原文给出 GPT-6.1 Sol 与 GPT-6 Astra 的价格与错误率对比，读者可据此判断其性价比定位。
正文
OpenAI launched GPT-6.1 Sol.
> near GPT-6 Astra level intelligence at a fifth of the price.
> across all reasoning settings, it's error rate stays within 1.9% of GPT-6 Astra.
> It improves factual accuracy when given difficult prompts. Its largest gain over GPT-6 Sol on this front appears at low reasoning effort, where the share of responses containing a factual error drops from 11.4% to 7.7%.
Also not launching GPT-6.1 Astra, as was originally expected for today.
GPT-6.1 Sol: near-Astra intelligence for a fifth of the price. It’s the most cost-efficient model for its performance available today. https://t.co/hH8PnE2Oxk在 X 查看被引用的帖子
