周二，Anthropic发布新一代模型Claude Opus 5.5，使用成本较前代降低约40%；OpenAI同日推出ChatGPT-6的两款低价版本Sol和Luna，定价较ChatGPT-5.6系列降低50%。两家公司几乎同步出手，时间节点的高度重合，清晰勾勒出当前AI市场的竞争烈度。
此次降价攻势背后，是来自中国"开放权重"模型的持续施压——这类模型允许用户自行定制并在本地硬件上运行。与此同时，Anthropic正积极备战今秋计划中的IPO，外界预计此次上市规模将创历史之最；OpenAI则在年初增长乏力后，寄望于降价策略重燃增长动能。
定价细节：Anthropic与OpenAI的价格坐标
在具体定价上，Anthropic的Opus 5.5每百万输入token收费4美元，每百万输出token收费20美元，而其现有最强模型Fable 5.1的对应价格分别为10美元和50美元——与OpenAI旗舰模型Astra的定价持平。Anthropic表示，Opus 5.5在大多数任务上的表现可与Fable 5.1媲美。
OpenAI方面，Sol定价为每百万输入token 2美元、输出token 10美元；轻量版Luna则低至每百万输入token 0.10美元、输出token 0.50美元。 OpenAI本月初已率先发布其最强模型Astra，Sol和Luna作为该系列的低价补充版本随后跟进。
