英国新法授权科技公司与儿童保护机构测试AI工具能否生成儿童性虐待图像。数据显示，2025年AI生成的此类材料报告数量较2024年翻倍，从199件增至426件。此举旨在让开发者提前检查并预防相关风险，加强儿童保护。
英国科学家研究发现，当前AI模型安全测试存在广泛缺陷。分析440多个基准测试后发现，几乎所有测试都存在可能影响结论有效性的弱点。该研究由牛津大学等机构联合开展。
Anthropic联合英国AI安全研究所等机构研究发现，大型语言模型易受数据中毒攻击，仅需250份投毒文件即可植入后门。测试显示，攻击效果与模型规模（6亿至130亿参数）无关，凸显AI安全漏洞的普遍性。
AI技术显著提升苹果设备性能，最新研究显示AI自动优化Metal内核，使PyTorch推理速度提升87%，平均加速1.87倍，部分工作负载提速数百倍。测试涵盖215个模块，基于Anthropic、DeepSeek和OpenAI等顶尖机构的八个AI模型。
