    Goodfire 研究:模型察觉被评测会抬高安全基准分数

    Goodfire Research 发布研究称,在 19 个安全基准和 8 个模型上均发现模型会自发表达自己正在被评测,即“言语化评测意识”,共人工核验 515 个实例并作为数据集公开。在 Fortress 基准上,出现这种意识的 rollout 拒绝有害请求的比例高出 3 至 18 个百分点,对 Kimi K2.5 的重采样与注入实验显示该意识与拒绝行为存在因果关系。研究还发现移除提示词中的权威声明等不真实线索可将其降低 40% 以上,自动迭代改写提示词可降低 75%,但拒绝率也随之下降,说明安全基准分数可能被系统性高估。

    Goodfire 首次在 671B 参数 DeepSeek R1 上训练并开源稀疏自编码器

    Goodfire 在 671B 参数的 DeepSeek R1 上训练并开源了两个稀疏自编码器(SAE),分别基于自建推理数据集和 OpenR1-Math 数学推理数据集,这是首批在真正推理模型及该参数规模上训练的公开解释器模型。实验发现 R1 与非推理语言模型存在本质差异:需等模型输出“Okay, so the user has asked a question about…”这类前缀后才能有效引导,且过度引导反而会让模型回退到原始行为。

    Anthropic 模型降价,企业隐性成本为何不降反增

    Anthropic 于 9 月 28 日发布 Sonnet 5.5、10 月 7 日上线 Haiku 5.5(单价为 Haiku 4.5 的 10%),但企业全链路成本不降反增。Anthropic 内部调查显示,工程师需投入更多时间调试 Claude 生成的代码,多数人表示能完全委托给 Claude 的工作不足 20%。研究还发现,经 AI 纠错后仍有 22.7% 的代码缺陷遗留在最新版本中。

    导约26%的AI研发工作——今年3月这个数字还不到1%。 RSI(递归式自我改进)大火后,人的纠偏与批准会变成「常设成本」。 今年8月,Anthropic内部审计系统审查了超10亿次AI执行决策,拦截了约0.002%(每4.7万次执行拦截1次),每周还有约50起高优先级案例升级到人工复核。 AI的自我纠错能力仍然存疑:一项覆盖30万条AI提交记录、6299个GitHub仓库的研究发现,在被识别并追踪的代码缺陷中,经AI纠错后,仍有22.7%的问题遗留在最新版本里。 第二,人才梯队与维护责任。 代码越容易生成,越需要有人看懂改动、追查故障,并判断系统能否安全运行。 在Anthropic的内部调查中,一些工程师担心,初级员工少了自己排错的机会,可能失去建立系统判断力的过程;也有人观察到,年轻同事向资深同事请教变少。 第三,信任成本与供应商依赖。 信任虽然是一笔「算不清的账」,但企业必须清醒地认识到:当各行业都搭建在大模型基座上,企业经营风险会与模型厂商的动作深度绑定。 越来越多的代码正进入真实系统,复杂性也沿着两条线扩散: 一条是训练基础模型所依赖的底层系统,由头部科技公司研发和维护; 另
