全球大模型市场现价格与生态调整。Anthropic推出低价轻量模型Claude Haiku5.5，单价降至上一代十分之一，短上下文API裸价低于部分国产小模型；OpenAI宣布GPT-6全量上线，同代小模型GPT-6Luna下放至ChatGPT免费层。两大海外巨头同期下调小模型价格，引发业界高度关注，深层商业逻辑待观察。
Anthropic在上市前夕发布新一代旗舰大模型Fable5.1，并同步向Mythos访问权限用户推出Mythos5.1。作为其产品体系最强核心，该模型多项基准测试全面超越上代Fable5及竞品，同时大幅削减使用成本，延续超强性能，凸显大模型军备竞赛正向极致性价比延伸。
智谱AI发布GLM-5.3-Flash，即开源社区神秘模型“Ox-Alpha”。作为GLM-5系列首个原生多模态模型，其性能对标全球顶级旗舰，并以颠覆性价格和全国产算力底座改写行业竞争规则。
OpenAI于7月31日公布GPT-5.6系列新定价，中端及轻量模型大幅降价，旗舰款不变。轻量级Luna模型成焦点，输入与输出费用同步削减80%，每百万输入Token降至0.2美元，输出亦相应大幅调低，掀起AI价格战新浪潮。
