Anthropic发布新一代大模型Claude Sonnet5，定位日常高频工作流主力，主打卓越编码、工具调用与逻辑规划能力，性能指标逼近旗舰Opus4，再次刷新AI模型迭代速度。
Anthropic发布新一代AI模型Claude Fable5，作为最强大众版，在生物学、网络安全等领域潜力巨大。但实际使用中，它表现出“选择性失忆”：面对高中基础生物学问题也拒绝回答，并转接给前代Claude Opus4.8。这并非能力不足，而是Anthropic出于极高安全标准所致。
Notion 官方宣布已全面恢复对Anthropic旗下Claude系列AI模型的访问权限。此前因Opus4.7和4.8模型性能下降，导致用户请求失败率攀升，Notion曾紧急禁用所有Anthropic模型。经过约12小时修复底层基础设施故障，集成服务现已恢复正常。
AI初创公司MiniMax发布旗舰大模型M3，性能惊艳：在接近真实软件工程场景的测试中取得59%成绩，超越GPT-5.5，逼近Opus4.7，具备百万级上下文处理能力和原生多模态特性，但发布后引发争议。
