Anthropic宣布7月20日起调整Fable5订阅策略：Max/Team Premium用户保留访问但限额大减，奖励期后常规额度再减33%，实际可用额度仅为调整后限额的50%；Pro/Team Standard失去权限，获一次性100美元额度后按API付费。因高频调用。
埃隆·马斯克的AI公司xAI被曝利用Anthropic的Claude模型数据训练Grok编码模型，尽管Anthropic于2026年1月撤销其API访问权限，xAI工程师仍通过个人账户和第三方服务Blackbox AI秘密提取数据。马斯克此前在法庭上承认xAI“部分”使用了该数据。
OpenAI通知API客户，将于2026年2月16日终止chatgpt-4o-latest模型访问权限。开发者有约三个月过渡期。该调整仅影响API服务，GPT-4o仍继续供ChatGPT免费及付费用户使用，暂无消费者端移除计划。
Anthropic宣布终止OpenAI对其Claude模型的访问权限，理由是OpenAI在GPT-5开发过程中违规使用Claude进行性能对比，违反服务条款。OpenAI回应称其行为符合行业标准，对决定表示失望。值得注意的是，Anthropic仍保留部分API权限用于基准测试，显示出两家AI巨头既竞争又合作的微妙关系。该事件凸显了AI行业日益激烈的技术竞争态势。
