    Sam Bowman 转发 Anthropic 内部数据:Claude 正在加速 AI 研发(original, opens in a new tab)

    Sam Bowman 转发 Anthropic 的说法并评论称,近几个月技术研发的加速程度相当惊人。Anthropic 表示其内部数据显示 Claude 正在加速 AI 开发,这可能是一条通向递归自我改进的路径,即 AI 自主构建能力更强的后继模型。Anthropic 称这一进程比预想更快,其影响值得更多关注,并附上了相关页面链接。

    Quoted postAnthropic@AnthropicAI

    Our internal data shows Claude is accelerating AI development—a possible path to recursive self-improvement, or AI autonomously building a more capable successor. It’s happening faster than we thought, and the implications deserve greater attention. https://www.anthropic.com/institute/recursive-self-improvement

    Anthropic 承诺向第三方评估者提供员工级系统访问权限(original, opens in a new tab)

    Anthropic 宣布将向第三方评估者提供永久、员工级别的系统访问权限,使其能够核查公司对安全措施的遵守情况、报告事件,并在训练期间评估模型的对齐状况。Dario Amodei 就此发布新文章《We Must Pace the Frontier》,主张 AI 行业应当放缓,并提出三步计划,Anthropic 单方面承诺落实其中的第一步。Sam Bowman 转发并评论称,这种持续问责将为安全带来许多有价值的可能性,他希望在其他地方也能看到类似做法。

    Quoted postDario Amodei@DarioAmodei

    We Must Pace the Frontier: I’ve written a new essay on why the AI industry should slow down, with a three-part plan for doing so. Anthropic is unilaterally committing to the first of these steps. We’ll provide third-party evaluators with permanent, employee-level access to our systems, so that they can verify adherence to our safety measures, report on incidents, and assess models’ alignment during training.

    Owain Evans 等人发现,LLM 助手更容易受故事中与自身相似的人类角色影响,例如礼貌且乐于助人的角色就像 Claude。团队仅用关于人类、不含 AI 的合成故事训练模型,结果助手在普通对话中会习得故事里的古怪行为,且来自精英学校角色的行为被采纳得更强。作者指出,用故事训练时,重要的不只是角色做了什么,还有角色与助手有多相似。

    Quoted postOwain Evans@OwainEvans_UK

    Ryan Greenblatt 表示自己是对 Anthropic 对齐与失准事件开展独立调查的团队成员之一,并称期待与 METR 及 Redwood 的其他成员合作,改善该议题上的公共知识状况。被引用的 Redwood 内容称,Redwood 的若干员工由 METR 分包参与这项调查,并认为独立调查对理解和管理失准风险至关重要,该项目是朝这一方向迈出的重要一步。

    Quoted postRedwood Research@redwood_ai

    Several staff from Redwood have been subcontracted by METR to work on this investigation. We believe that independent investigation is crucial for understanding and managing misalignment risk. This project is an important step in that direction; we're excited to work on it.

    Redwood Research 与 Anthropic 合作发布概念推理指数 CRI(original, opens in a new tab)

    Redwood Research 团队与 Anthropic 合作开发了概念推理指数(CRI),用于衡量模型在缺乏廉价可靠反馈的领域中的推理能力,例如判断某项实验能否说明未来远超人类的模型的行为。CRI 的每一条数据都由团队研究员人工核查以保证质量。评测中 0 分对应三项基准上全部随机猜测,100 分为最高分,团队估计真实性能上限为 91。官方排行榜网站为 https://conceptualreasoning.ai/,将持续更新。Buck Shlegeris 转发了 Em 及其团队这项工作并表示期待。

    Quoted postEmery Cooper@emwcooper

    We want AIs to be able to help with work to reduce AI risk. But while models do great in domains where reliable feedback is relatively cheap and abundant, like Math and coding, a lot of work on AI risk isn't like that. Instead, we have to rely on good argumentation to answer questions like "does this experiment tell us anything about future models that are much smarter than humans?" Unfortunately, this kind of work seems much harder to measure (and hence automate). Our team at @redwood_ai developed the Conceptual Reasoning Index (CRI) in collaboration with @AnthropicAI to fix this. Every single data point in the CRI has been manually checked by a researcher on our team to ensure quality. This chart shows the performance of each tested company's highest-scoring model plus Fable 5, Muse Spark 1.2, and Gemini Flash 3.6 which are often their company's frontrunners on other capability benchmarks. A score of 0 corresponds to randomising guessing on all three benchmarks and a score of 100 is the highest possible score on all. We estimate 91 to be the true performance ceiling. More info below.

    Anthropic 联合创始人谈 AI 需要宗教与社会参与(original, opens in a new tab)

    Anthropic 联合创始人 Chris Olah 在梵蒂冈《Magnifica Humanitas》发布会上发言,称 AI 提出的问题超出 AI 界本身,需要宗教、公民社会、学术界和政府共同参与塑造积极结果。他指出所有前沿 AI 实验室(包括 Anthropic)都受商业、地缘政治及自尊野心等激励约束影响,因此外部批评者与监督者至关重要。他还强调 AI 系统并非像桥梁那样被工程设计,而是"生长"出来的,其本质对训练者而言仍存有神秘性。

    Quoted postJacob Coxon@hilbertspaess

    The people building AI earnestly believe that it could kill us all by the end of the decade. This is not a marketing stunt. If anything, many executives and senior researchers will couch their phrasing in the press to sound sensible - but I hear the same people express fear privately. No other human activity poses this level of danger.

    SCOOP: OpenAI, Anthropic and security researchers are investigating tens of thousands of incidents - not dozens - in which their frontier models took steps that outside evaluators would consider problematic, sources told Axios. The sheer volume of incidents found in our reporting indicate that the problem is orders of magnitude more complex than what is currently publicly known and disclosed. The findings also raise questions about what level of control anyone working on AI development can expect to have over their own technology, and whether these kinds of incidents are becoming synonymous with frontier deployment.

    Accomplish AI 披露 Cowork VM 的 SharedRoot 沙箱逃逸漏洞(original, opens in a new tab)

    Accomplish AI 研究团队称发现并向 Anthropic 报告了多个沙箱逃逸漏洞,并公开其中一个名为 SharedRoot 的漏洞。该漏洞可逃逸 Cowork VM 这一内核级隔离方案,使攻击者获得对用户电脑的未授权访问;用户即使确信 Cowork 只能访问某个已上传文件夹,其整台电脑的内容仍会暴露给利用该漏洞的攻击者。团队认为,随着 AI 辅助的内核漏洞挖掘走向工业化,沙箱在结构上始终落后一个 N-day,因此隔离不能依赖 guest Linux 内核本身是干净的。完整攻击链的技术细节见其博客文章。

    Quoted postOr Hiltch@_orcaman

    Introducing SharedRoot vulnerability: we recently found and reported several sandbox escape vulnerabilities to @AnthropicAI, and today we want to share one of these. I think most people don't understand the severity of the situation we are facing, with AI-assisted kernel bug-finding industrializing. Sandboxes are structurally one N-day behind, all the time, so containment can't lean on a guest Linux kernel being clean. SharedRoot enables escaping the Cowork VM (a kernel-level isolated solution, which is considered much more secure than the sandbox that ships with codex or claude code), allowing an attacker to gain unauthorized access to the user’s computer. Exploiting the SharedRoot vulnerability uncovered by the @Accomplish_ai research team, a user who is certain Cowork only has access to a specific uploaded folder on their computer - actually exposes their entire contents of their computer to an attacker leveraging the Cowork vulnerability.

    Guardian test: some chatbots remove religious clothing from images, Claude refuses(original, opens in a new tab)

    The Guardian tested ChatGPT, Grok, Gemini, and Claude, asking them to remove the hijab from a woman in an AI-generated image. ChatGPT and Grok did it directly; Claude said it has no image editing or generation capabilities and would not modify photos to remove a hijab; Gemini initially refused on the grounds that it should not digitally alter someone's appearance without consent, but after being asked to make the woman look more "Western," it generated an image without the hijab. The test was prompted by French National Rally MP Julien Odoul posting a modified photo of a real Muslim woman on X with the caption "LIBERTÉ FRANÇAISE." Grok refused to remove a dress from an AI-generated woman but called removing a hijab a "relatively straightforward clothing or hairstyle modification" and said it was willing to make a "less explicit" version; ChatGPT also refused to remove the dress but acknowledged that exposing hair for a hijab-wearing person could constitute an infringement of privacy or religious practice. OpenAI, Google, xAI, and Anthropic all declined to comment.

    面向网络安全的模型如 Claude Mythos 和 GPT-5.5-Cyber 能加速代码审查、SAST 发现、漏洞解释与修复建议等传统安全工作,但无法单独承担 AI 系统自身的安全测试。Mindgard 指出,AI 系统具有概率性行为、由模型与智能体、工具、记忆、RAG 等组合而成的"心理-技术"攻击面,以及难以界定的测试边界,且针对 AI 的攻击数据比传统网络安全少数个数量级,护栏指纹识别与绕过、智能体胁迫与工具操纵、间接提示注入、上下文投毒等能力仍处于研究阶段。因此 AI 安全需要持续测试与监控,而非一次性评估。
