OpenAI 发布 GPT-6 Sol 与 Luna：价格减半，性能提升有限
原标题：OpenAI's GPT-6 Sol and Luna cut prices in half but barely move the needle on performance
AI 摘要
OpenAI 发布 GPT-6 Sol 和 Luna 两款模型，token 价格较 GPT-5.6 同系列减半，Sol 为每百万输入 2 美元、输出 10 美元，Luna 为输入 0.10 美元、输出 0.50 美元，同时将缓存输入 token 折扣提升至 90%。OpenAI 称降价源于缓存与推理优化，并将新模型定位为对标 Anthropic Claude 系列的性价比选择。但 Artificial Analysis 的独立分析显示，两款模型的智能分数仍停留在 GPT-5.6 水平，部分知识工作基准甚至出现回退。

OpenAI's GPT-6 Sol and Luna cut prices in half but barely move the needle on performance With GPT-6 Sol and Luna, OpenAI adds two cheaper models to its lineup that match their predecessors' performance at half the token price and aim to rival some of Anthropic's more expensive models. The biggest change is a 50 percent price cut compared with GPT-5.6 Sol and Luna. GPT-6 Sol now costs $2 per million input tokens and $10 per million output tokens, while Luna comes in at $0.10 for input and $0.50 f
