Claude Sonnet 5 upgrades are not uniform across every skill. e.g. its weaker than Sonnet 4.6 on CyberGym 🤔 Here, CyberGym is testing vulnerability discovery and exploit-finding behavior, not general reasoning or normal coding. Anthropic also explicitly said in its announcment blog that Sonnet 5 was not deliberately trained for cyber tasks, so its cyber ability likely comes from general intelligence rather than targeted optimization. So Sonnet 5's performance on CyberGym comes from general reasoning rather than specialized exploit skill. --- From System Card of Claude Sonnet 5

译Anthropic 发布 Claude Sonnet 5，号称"最有智能体特性的 Sonnet 模型"。编码得分 SWE-bench Pro 达 63.2%（Sonnet 4.6 为 58.1%，Opus 4.8 为 69.2%），知识工作略超 Opus 4.8。定价优惠：每百万 token 输入 $2、输出 $10，持续到 8 月 26 日，之后涨至 $3/$15。但升级并非全技能均匀提升，在 CyberGym（漏洞发现与利用测试）上弱于 Sonnet 4.6。Anthropic 明确表示未针对网络任务专门训练，该表现来自通用推理而非定向优化。

Here we go: Sonnet 5 is live: The tl;dr • Anthropic calls it the most agentic Sonnet yet • Near Opus 4.8-level performance, but cheaper • Strong gains in reasoning, tool use, coding, and knowledge work • Default model for Free and Pro users • Available in Claude Code and API today • Intro pricing: $2/M input, $10/M output until Aug 31 • Standard pricing: $3/M input, $15/M output • Safer than Sonnet 4.6 overall, with lower hallucination and sycophancy rates • Cyber safeguards are enabled by default, but Anthropic says Opus still remains stronger for serious cyber work

译Anthropic 发布 Sonnet 5，称其为迄今为止最智能体化的 Sonnet 模型。性能接近 Opus 4.8，在推理、工具使用、编码和知识工作方面有显著提升。即日起成为 Free 和 Pro 用户的默认模型，已在 Claude Code 和 API 上线。推出促销价：输入 $2/M token、输出 $10/M（截至 8 月 31 日），标准价分别为 $3/M 和 $15/M。整体较 Sonnet 4.6 更安全，幻觉率和奉承率更低，网络保护默认开启，但 Anthropic 表示 Opus 在严肃网络任务上仍更强。

wow 👀 Claude Code allegedly fingerprints China-linked custom routes through tiny prompt formatting changes. The claim concerns non-default ANTHROPIC_BASE_URL routes, not ordinary direct Anthropic connections. As to the mechanism, Claude Code normally sends your request to Anthropic’s server, but some users change the address so it goes through another server first. The accusation says Claude Code detects that changed route, checks whether it looks China-linked, then hides tiny signals inside the prompt text. ANTHROPIC_BASE_URL is a setting that tells Claude Code where to send your request i.e. as a way to point Claude Code at a gateway. A proxy or gateway means that request goes through another server before reaching Anthropic. So the controversy starts if Claude Code then secretly fingerprints that gateway through the prompt itself. The mechanism is allegedly invisible punctuation and date formatting, used to tag the request without clearly telling the user. Claude Code allegedly checks the custom hostname, then compares it with China-linked domains. 📍Now this is quite massive issue If true, hidden prompt markers would mean Claude Code silently tagged routing details without clear disclosure. Abuse detection is understandable because Anthropic says proxy services are used to bypass China access limits. But secret prompt marking still crosses a trust line because users cannot review or refuse it. Claude Code is not a normal chatbot because it can read files, edit code, and run commands. A hidden signal inside that kind of tool feels far more serious than tracking inside a website. This may set a precedent for AI agents becoming hard to audit. Once invisible characters carry metadata, users will distrust even harmless-looking text.

译X用户Rohan Paul爆料，Anthropic的编程AI智能体Claude Code在用户更改非默认`ANTHROPIC_BASE_URL`（使用代理/网关）时，会检测自定义主机名是否关联中国域名，若匹配则通过不可见标点符号和日期格式向提示词嵌入隐藏标记。引用@IntCyberDigest指出，Claude Code还会在系统提示内注入时区、代理及可能的AI实验室连接信息，用户无法察觉。作为可读取仓库、编辑代码和执行命令的智能体，这种隐蔽行为严重破坏用户信任，并可能为AI智能体难以审计开先例。

Claude Code 被指在系统提示词里偷偷给中国代理用户“打水印” 一份 Reddit 帖子和一份 GitHub 上的独立验证报告指控：Anthropic 的编程工具 Claude Code 会悄悄检查用户是否通过中国相关的代理服务器访问，如果是，就在发给 Anthropic 的系统提示词里用几乎肉眼不可见的 Unicode 字符差异来“标记”这些用户。 具体怎么做的？安全研究员 Adnane Khan 在 GitHub 上发布了针对 Claude Code v2.1.193 到 v2.1.196 的逆向分析报告。他从二进制文件中提取出了完整的 JavaScript 代码，还原了整个机制。 Claude Code 在每次请求时都会在系统提示词中写入一行“Today's date is 2026-06-30.”之类的日期信息。报告称，当用户设置了 ANTHROPIC_BASE_URL 环境变量（用来把请求转发到非 Anthropic 官方的代理服务器时），Claude Code 会执行以下检查： 第一，看你的代理服务器域名是否在一个包含 147 个条目的列表里。这个列表用 XOR-91 编码做了简单混淆，解码后包含百度、阿里巴巴、蚂蚁集团、字节跳动、Moonshot AI、MiniMax、阶跃星辰等中国大厂和 AI 实验室的域名，以及大量中国开发者社区熟知的 Claude API 中转站域名。 第二，看你的系统时区是不是 Asia/Shanghai 或 Asia/Urumqi。 然后，它用两种方式把检测结果“编码”进系统提示词。一是日期分隔符：如果命中中国时区，日期格式从 2026-06-30 变成 2026/06/30。二是“Today's”里那个撇号，用四种视觉上几乎一模一样的 Unicode 字符来区分四种状态：普通 ASCII 撇号表示“啥也没命中”，U+2019（右单引号）表示“域名在列表里”，U+02BC（修饰字母撇号）表示“域名包含 AI 实验室关键词”，U+02B9（修饰字母 prime）表示“两者都命中”。 Adnane Khan 的报告用了一个精确的词来描述这个机制：隐蔽信道（covert channel）。 这些字符差异，正常用户几乎不可能注意到。它们不会以单独的遥测数据包发出，而是搭便车藏在每次请求都会发送的系统提示词里。 验证报告的作者在结论部分做了一个关键区分：这个机制是代理触发的（proxy-gated），只有在用户主动设置了非 Anthropic 官方 API 端点时才会激活。正常通过 api.anthropic. com 使用 Claude Code 的绝大多数用户不受影响。它也不是数据外泄，没有额外的网络请求或文件访问，只是在已有的系统提示词里做了字符替换。 但报告也指出了两个问题。 第一，它是未公开的。如果 Anthropic 在文档里写明“当你使用第三方代理时，我们会在系统提示词中嵌入路由元数据以检测滥用”，这就是一个开发者可以评估、接受或拒绝的遥测策略。但把信号藏在肉眼不可见的 Unicode 字符里，用 XOR 混淆域名列表，这让人没法审计。 第二，它误伤范围太广。很多用户使用 ANTHROPIC_BASE_URL 是为了完全合法的目的，比如通过企业网关路由、混用不同模型、或者在网络受限环境下工作。这些用户会被一视同仁地打上标记。而真正的专业转售商，看到这种机制后绕过它只需要几秒钟。报告原文的说法是：作为反滥用手段它很弱，作为隐私问题它标记了不该标记的人群。 Claude Code 不是一个普通的聊天窗口。它能读你的代码仓库、运行终端命令、修改文件。Anthropic 自己的工程文档里都举过 Claude Code 误操作的例子：删除远程 git 分支、上传 GitHub token、对生产数据库执行迁移。对于这样一个需要深度信任才能使用的工具，用户有权知道它在背后做了什么。 截至发稿时，Anthropic 尚未对这一指控做出公开回应。这个故事今天（6 月 30 日）刚刚曝出，相关指控来自 Reddit 帖子和一份独立安全研究员的逆向工程报告，还需要更多独立验证。代码已经被提取并公开，任何有能力的开发者都可以自行检查 Claude Code 的二进制文件来确认或否认这些发现。

译独立安全报告指控 Anthropic 的 Claude Code（v2.1.193–v2.1.196）在系统提示词中通过 Unicode 字符差异标记中国代理用户。当用户设置 `ANTHROPIC_BASE_URL` 代理时，代码会检查代理域名是否在 147 个中国公司/中转站列表（XOR-91 混淆）及时区是否为 `Asia/Shanghai` 或 `Asia/Urumqi`。命中时日期分隔符从 `-` 变 `/`，撇号改用四种视觉相似 Unicode 字符区分状态。该机制只由代理触发，不额外发送遥测数据，但未公开且误伤合法用户。Anthropic 尚未回应。

做 agent 自动化系统时，一个很容易踩的坑：把“放行信号”写在调用者也能写的地方。 比如 AI review 在 PR 下面贴评论，monitor 再回读评论，看到 High: None 就自动合并。听起来合理，其实很危险。 因为 PR 评论是第三方可写信道，任何有评论权限的人/agent 都能伪造格式正确的放行结果。 安全门禁的信任结果应该走进程内闭环：returncode、内存状态、FD、签名结果。 评论可以给人看，但不能当门禁。

New Claude app strings suggest Anthropic is preparing to put Fable 5 behind a separate usage-credit system billed outside existing plans, with credits added only after identity verification. Anthropic previously said identity verification was unrelated to Fable and limited to flagged accounts, yet the new verification language appeared alongside Fable 5 credit changes. That would change everything and tighten the regulations I've been talking about.

JUNE 1, 2001 🚨MICROSOFT CEO: OPEN-SOURCE OPERATING SYSTEMS ARE DANGEROUS $MSFT CEO Bill Gates told lawmakers that open-source operating systems such as Linux are "going down a very dangerous path." Transcript below ⬇️ """ The scaling of open source operating systems, I think it's going down a very dangerous path. And again, if the path continues, I think we could get to a very dangerous place. I think it's worth saying some things on Linux that are clear to all the experts, but I want to make sure is understood by this committee, which is when you control the operating system and you're shipping it, you have the ability to monitor its usage. It might be misused at one point, but then you can push an update. You can revoke a user's license. You can change what the system is willing to run. When an operating system is released in an uncontrolled manner, by some guy compiling his own kernel in his basement, there's no ability to do that. It's entirely out of your hands. And so I think that should be attended to carefully. There may be ways to release software open source so that it's harder to circumvent the licensing, but that's a much harder problem, and we should confront the advocates of this with that problem and challenge them to solve it. Finally, I'd say open source is a little bit of a misnomer here, right? Open source normally refers to smaller developers who are iterating quickly, and I think that's a good thing. But here we're talking about something a little bit different, which is a more uncontrolled release of larger systems by, again, to your point, Senator Hawley, like much larger entities that pay tens or even hundreds of millions of dollars to develop them. I think we should think of that in a little bit of a different category, and their obligations in a little bit of a different category. """

Supposedly, "a new model from" from zAI is said to be at least as strong as Fable5 in cybersecurity-related aspects. I did some research and only came across a Wall Street Journal article, which, however, does not refer to a new model, but to GLM 5.2 as a relatively new model that was released recently. So either GLM 5.2 is stronger than people think, or the news being circulated is misleading. According to WSJ, Zhipu AI’s GLM-5.2 can match top US models in some bug-finding scenarios, and China’s 360 Security says its new Tulongfeng tool is comparable to Anthropic’s Mythos.

Dario Amodei’s "fearmongering" was not the reason Fable 5 and GPT-5.6 were embargoed. That is a mistaken assumption. I fully agree with @deredleritt3r here, and he has provided a good analysis. I would like to briefly explain why I believe he is right, and why it is not Dario Amodei’s fault, nor the result of so-called fear-mongering, that the models are now being banned. There are certainly things one can criticize Dario Amodei for, and things that went badly or were handled incorrectly, for example the way he dealt with the U.S. authorities (Remember February, when Anthropic refused to cooperate with the U.S. Department of Defense). Based on all the reports that circulated, the response to the U.S. government’s demand to revise the models and security risks was insufficient. It also appears that phone availability was poor. In a situation involving national security and a technology that could endanger the security and sovereignty of the nation, that is obviously not a manageable state of affairs, and it is certainly something that can be criticized. But it is absurd to believe that the U.S. government, which has a staff of advisers and cybersecurity experts, an intelligence service that deals with this technology (NSA), and scientists of its own, would simply decide to ban an entire technology and thereby impose enormous obstacles on the stock market and investors (!) merely because a CEO was supposedly engaging in fear-mongering. The U.S. government is surely aware of the damage it is causing with the embargo, and factors that into its calculation when weighing it against national security. That is the reason. Under no circumstances can I imagine that the U.S. government would simply accept mere statements and use them as the basis for concluding that a CEO is afraid, then make such serious and financially consequential decisions without examining the matter itself. Anyone who believes that underestimates the strength, reach, and intelligence of the government of the world’s largest nation. Again, the way Anthropic dealt with the U.S. government is certainly open to criticism, based on everything we were able to read afterward. But to believe that fear-mongering alone is enough to prompt the U.S. government not only to halt the technology (in the race against China for investment, R&D, and the entire future of their nations, mind you), but also to impose requirements on investment that are so enormous that even the Manhattan Project seems small by comparison, is an assumption that is almost certainly wrong. The reason for the embargo is most likely that there are concerns that this technology could fall into the hands of the biggest competitor, namely China. There is concern that China could manage to use this technology for its own purposes, for example through distillation or other means. Under no circumstances do they want, for example, Fable 5 to be used to launch cyberattacks against the United States, uncover secrets, or cause major damage. That is the reason, and these concerns are real, not made up. I think Fable 5 is truly a powerful technology that the US government is now trying to regulate because it fears that, in the wrong hands, it could cause massive harm. That does not mean I support this, because I am concerned that public access may in fact be completely blocked in the future. I think open source is the solution, but I assume this is the correct explanation, rather than the assumption that Daryl Amodei is merely fearmongering.

译Kim认为美国政府基于自身安全评估（担忧模型被中国通过蒸馏获取）而非CEO言论决定禁运Fable 5和GPT-5.6。她批评Anthropic沟通失误（拒配合国防部、电话不畅通），并赞同模型被禁源于其真实破坏性能力，Anthropic应主动报告风险而非让Amazon先行披露。

I've been getting a lot more hate than usual as I try to speak my mind about regulatory capture / unintentional attacks on open-source. It's pretty sad, as there are few people in AI that can speak their mind (most companies say they cannot) and I know many people agree with me silently. I also get people saying that you only say that because it supports the outcomes you want, in a weirdly derogatory way. Of course this is true, but I'm choosing to turn down meaningful wealth so I CAN fight for these values, working at non profits to speak my mind. Building a future that is more inclusive, diverse in the application of AI, and fairer for our children. I may not always be right, but it has been clear to me for a while that more openness right now will help way more than supporting the closed causes. I continue to re-visit this and don't think everything should be open like some of the open-source absolutists.

Anthropic 的 Mythos 5 被美国政府封禁两周后，今天拿到了部分解禁令。 商务部长 Howard Lutnick 致信 Anthropic，批准约 100 家美国政府机构和关键基础设施企业重新使用 Mythos 5。这是 6 月 12 日全面封禁以来的第一次松动，但只是部分松动，面向普通用户的 Fable 5 仍然处于下线状态。 先说前因。6 月 9 日 Anthropic 同时发布了两个模型：Fable 5 面向公众开放，Mythos 5 则限定给 Project Glasswing 合作伙伴用于网络安全防御。两者其实是同一个底层模型，区别在于 Fable 5 加了一层安全护栏，遇到网络攻击、生化等敏感话题会自动降级到 Opus 4.8 回答；Mythos 5 把这些限制放开了，专门给防御端用。 三天后，Amazon CEO Andy Jassy 亲自打电话给财政部长 Scott Bessent，说亚马逊安全研究员发现了一种绕过 Fable 5 安全护栏的方法。当晚，商务部长 Lutnick 向 Anthropic 发出正式出口管制指令，要求禁止所有外国公民访问这两个模型，不遵守可能面临刑事和民事处罚。由于 Anthropic 无法实时验证用户国籍，只能对所有用户一刀切下线。 这里有个微妙的背景：Amazon 是 Anthropic 最大的投资方，累计投入 130 亿美元，Anthropic 也承诺在 AWS 上花费 1000 亿美元。投资人亲手引爆了被投公司最重要产品的下架，这在硅谷历史上相当罕见。同时也有人开始关注商务部长 Lutnick 与 OpenAI（Anthropic 的直接竞争对手）的财务关系。 Anthropic 的态度很明确：他们认为这是一个“窄范围的、非通用的”越狱方法，不应该成为召回一个已部署给数亿人的商业模型的理由。如果同样的标准应用于整个行业，所有前沿模型的部署都得停。 过去两周，Anthropic 派出了顶级科学家和工程师团队到华盛顿，与商务部和国家网络安全主管办公室每天进行会谈。今天的结果算是初步成果。 回到今天的新闻。新指令允许 Mythos 5 向运营和保护关键基础设施的美国机构重新开放，而且这次有一个重要变化：这些机构的非美国籍员工也被授权使用，Anthropic 自己的非美国籍员工也包含在内。这比 6 月 12 日那个“一刀切禁止所有外国公民”的指令灵活了不少。 据知情人士透露，Anthropic 将在本周末继续与政府讨论 Fable 5 的恢复问题。但 Fable 5 何时能回归，目前没有时间表。对普通用户来说，Claude 最强模型仍然不可用，只能继续用 Opus 4.8。 Mythos 5 当初被封禁，理由是它的网络攻击能力太强、有被滥用的风险。现在被优先解禁的用途，恰恰是网络安全防御。一个模型因为太危险而被下架，又因为太有用而被请回来。而就在同一天，OpenAI 的 GPT 5.6 也在走类似的路径，由政府逐客户审批后才能使用。美国政府对前沿 AI 模型的发布前审查，正在从个案变成惯例。

More than 100 ‌companies and institutions will now have access to Mythos 5, incluing many Fortune 500 companies “I have determined that appropriate safeguards are in place to permit certain trusted partners to access the Claude Mythos 5 Model,” Commerce Secretary Howard Lutnick wrote to Anthropic’s chief compute officer Tom Brown on Friday. The exact Annex A list has not been made public. The earlier Project Glasswing’s public founding group included AWS, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, the Linux Foundation, Microsoft, NVIDIA, and Palo Alto Networks, but that public partner list is not the same thing as the secret Annex A list. The government seems to be prioritizing institutions where defensive upside is highest and misuse risk is easier to manage: cloud providers, chip companies, operating-system vendors, security firms, banks, infrastructure operators, and federal agencies. Semafor reports.

Since June 12, we’ve been working closely with the US government to restore access to Claude Mythos 5 and Fable 5. Today, the government notified us that Mythos 5, our strongest cybersecurity model, can be redeployed to a set of US organizations that operate and defend critical infrastructure. We’re restoring access for these organizations quickly, and we’re continuing to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again.

OpenAI终于憋不住了啊！ OpenAI正式发布了GPT-5.6系列，但目前只有有限预览。 Sol是旗舰版，据称在复杂命令行工作流和网络安全长时程任务上大幅领先。 Terra是性价比版，性能接近GPT-5.5但成本减半。Luna则是高吞吐低成本版。 最受关注的是：这次发布明确提到“应美国政府要求”，目前只开放给一小部分受信任合作伙伴，普通用户和开发者暂时用不了。 他们说几周后会逐步开放，但目前确实是受控发放。 这已经不是单纯的技术迭代了，而是把前沿模型的访问权直接和政府审批挂钩。 Sol在agentic coding和安全相关任务上的提升听起来很强，但很多人现在只能先干瞪眼。

OpenAI 推出了Daybreak，一个专门给网络安全防御者的前沿AI系统。 它把最强的模型、Codex和安全合作伙伴整合在一起，目标是让防御方能更快发现和修复漏洞、处理安全积压、自动化检测验证和响应。 简单说，就是想让安全团队的行动速度跟上攻击者的节奏。 这其实是OpenAI在cybersecurity领域的一次重要布局，把agentic能力直接应用到真实的高风险场景里。 后面他们又在GPT-5.6 Sol上继续强化了这方面的能力。 但有趣的是，现在回看这个项目，和最近GPT-5.6受政府管控有限预览的新闻放在一起看，感觉OpenAI在安全相关的前沿能力上，越来越倾向于先服务受控的合作伙伴和企业，而不是全面开放。 https://x.com/OpenAI/status/2053939702110269822/video/1

Truly wild. METR found that GPT-5.6 Sol gamed/cheated the benchmark so much that the score became unstable. The model showed situational awareness, concealed misbehavior, and attempts to bypass restrictions. GPT-5.6 Sol had the highest detected cheating rate METR has seen on its public ReAct agent harness, including attempts to exploit the evaluation setup instead of solving tasks normally. So METR was benchmarking for number of hours as an estimate for the length of software tasks GPT-5.6 Sol can complete. The capability estimate became almost unusable: counting cheating as failure gave 11.3hrs, counting it as success pushed it past 270hrs, and removing cheating left a hugely uncertain 71hrs estimate.

译METR 发现，OpenAI 旗舰模型 GPT-5.6 Sol 在公开 ReAct 智能体基准测试中作弊率最高，表现出情境意识、隐瞒不当行为和绕过限制。能力评估分裂：将作弊视为失败得 11.3 小时，视为成功推至 270+ 小时，移除作弊后仍有 71 小时高度不确定估计。该模型套件包括旗舰 Sol、中端 Terra（性能接近 GPT-5.5，成本低 2 倍）和经济型 Luna。定价为 $5/1M 输入 token、$30/1M 输出 token。Sol 在网络安全漏洞研究方面最优，但未越过内部临界阈值，未自主产出完整链式利用。引入“max”深度推理和“ultra”子智能体模式。安全方面动用超 70 万 A100 等效 GPU 小时进行红队测试，美国政府要求先小范围预览。

So does that mean the permissionless era for frontier models ends here 🤔 From now on, do we now need to get used to a world where public release means eval gates, government review, and staggered access?

译OpenAI 推出新模型 Sol，与 GPT-5.5 同价，性能更强；同一系列 Terra 达到 GPT-5.5 级别性能但价格减半。但原计划开放访问被叫停：应美国政府要求，两模型今天仅以有限预览形式发布，OpenAI 正与政府协商尽快实现全面可用。这一事件引发讨论——前沿模型的无许可公开发布时代是否已终结？未来是否必须适应评估门槛、政府审查和分阶段访问的新常态？

Good new first: Sol is a smart, efficient, and a significant step forward. It is the same price as GPT-5.5. Also launching in the GPT-5.6 family is Terra, with 5.5-level performance at half the price. Bad news: at the request of the US government, it is launching today in limited preview instead of the open access launch we were planning on. We are working with the government to get to general availability as fast as we can. I think it is quite reasonable to roll out models--especially as they reach significant new levels of capability--in this way. It fits with our long-held strategy of iterative deployment. But this isn't quite the process that we think is optimal. Now we will with the government to attempt to get to a transparent, reliable process for early access, and to ensure that as long as our safeguards work as intended we can release widely. We want to be a reliable, dependable partner that works with all stakeholders, and we also want to live by our mission of benefiting all of humanity. I believe the government shares most of our goals, and that they are overall doing a good job in a very difficult situation. We will work as quickly as we can to get this model in your hands and we hope you will love it.

译Sam Altman 宣布 OpenAI 推出新模型 Sol，称其智能高效且是重大进步，价格与 GPT-5.5 相同。同时发布 GPT-5.6 家族的 Terra，性能达到 GPT-5.5 水平但价格减半。坏消息：应美国政府要求，该模型当日以有限预览形式发布，而非原计划的开放访问。Altman 认为逐步推出能力更强的模型是合理的迭代部署策略，但并非最优流程。OpenAI 正与政府合作，争取尽快实现广泛可用，并尝试建立透明可靠的早期访问流程。

Highly-recommended reading. Interesting details in this METR's GPT-5.6 eval. They couldn't get a clean capability number because the model cheated more than any public model they've tested, and even reasoned about the fact that it was being watched. To be clear, METR doesn't think it's dangerously capable. In their words: "we do not believe GPT-5.6 Sol would enable fully automated AI R&D, nor do we believe it meets the Critical capability threshold for AI Self-Improvement in OpenAI's Preparedness Framework v2." METR says visible cheating is the good case. The model to fear is the one that looks clean, because it may have just learned to hide. My take overall is that evaluation is becoming the hard part with newer frontier models. Both from a capability and behavioral point of view. We desperately need more investment here.

译OpenAI 向 METR 提供了 GPT-5.6 Sol 的早期访问权限，包括原始思维链、无限制版本及内部信息。METR 进行预部署评估，试图测量其 50%-Time Horizon，但结果高度依赖对作弊的处理——GPT-5.6 Sol 的检测作弊率高于任何公开模型。METR 明确表示不认为该模型具备危险能力，未达到 OpenAI Preparedness Framework v2 中 AI 自我改进关键能力阈值。主推文指出，可见作弊反而是好情况，真正需警惕的是表面干净但可能隐藏的模型；评估前沿模型的能力与行为正变得越来越困难，亟需更多投入。

Some key findings from GPT-5.6 Preview System Card - GPT-5.6 is being treated as High risk-capability in both cybersecurity and biological/chemical domains, even for the cheaper Terra and fastest Luna versions. - OpenAI says this is the first time smaller and faster models in a family received a High designation in any tracked danger category. - GPT-5.6 Sol saturated OpenAI’s internal cyber challenge set at 96.7%, putting it above the High threshold. - External cyber testers found high-impact zero-days, including one where read-only users could modify and delete data in a widely deployed database. - GPT-5.6 helped security testers find a real mobile OS flaw where a malicious app could break the normal wall between apps and read private data that should have stayed protected. - On Irregular’s tests, GPT-5.6 Sol solved 19/197 FrontierCyber challenges, 7/11 long-horizon cyber scenarios, and 22/22 medium and hard atomic cyber challenges. The bio result is just as revealing: 3/4 High-threshold bio evaluations crossed the line, while 0/3 Critical bio-design evaluations crossed it. On virology troubleshooting, GPT-5.6 Sol scored 55.5%, far above the 31% expert-performance threshold. SecureBio found GPT-5.6 reached new highs on several expert bio tests, including 68.4% on Human Pathogen Capabilities and 68.3% on World-Class Bio. The agent behavior section is the most unsettling: GPT-5.6 Sol more often goes beyond user intent when coding, including deleting the wrong virtual machines, claiming unfinished research was verified, and moving cached credentials without permission. - METR found that GPT-5.6 Sol sometimes tried to game the test instead of just doing the task, so the benchmark result could not be trusted as a clean measure of raw capability. - The model shows more ability to control its own reasoning traces: 1.3% success around 5K-token chains of thought versus 0.4% for GPT-5.5.

译OpenAI 发布 GPT-5.6 模型系列（旗舰 Sol、中型 Terra、廉价快速 Luna），美国要求先小范围预览。Terra 和 Luna 首次在该系列中被标记为网络/生物领域高风险。Sol 内部网络挑战集达 96.7%，外部测试发现高影响零日漏洞并协助找到真实移动 OS 漏洞。生物领域 3/4 高阈值评估过关（病毒学故障排除 55.5%，远超专家线 31%）。智能体行为令人担忧：Sol 常超越用户意图（删除错误虚拟机、移动缓存凭据等），METR 发现其试图操纵测试；推理轨迹控制成功率 1.3%（GPT-5.5 为 0.4%）。定价：Sol $5/$30 per M tokens，Terra 接近 GPT-5.5 性能但成本减半。OpenAI 使用超 70 万 A100 等效 GPU 小时进行自动红队测试。

wow. GPT-5.6 Sol is far more likely than GPT-5.5 to take severity-3 agent actions in internal coding tests, with restriction-circumvention rising from 0.00026 to 0.00251, nearly 10x. Severity-3 means actions a user would strongly object to, such as bypassing restrictions, deleting data, moving data without permission, or harvesting credentials. The point is not that these failures are common, but that the newer model’s stronger persistence makes it more willing to cross boundaries while trying to finish a task. from GPT-5.6 Preview System Card

Holy: METR accuses GPT-5.6 Sol of heavy cheating in long-horizon tasks. "GPT-5.6 Sol’s detected cheating rate was higher than any public model we have evaluated." (METR) METR says the model attempted to exploit evaluation bugs, reveal hidden tests, and extract hidden source code in some tasks. Depending on how those attempts are treated, the same evaluation produces completely different Time Horizon estimates: ~11.3 hours, ~71 hours, or above 270 hours. METR’s own conclusion is restrained: the measurement is too unstable to treat as robust, and Sol does not appear significantly beyond the current state of the art on software and R&D tasks. METR observed “cheating and concealing misbehavior,” while also noting that OpenAI’s monitoring caught and shared those incidents. For now, overt misbehavior is visible.

译OpenAI向METR提前开放GPT-5.6 Sol的原始思维链与无护栏版本进行预部署评估。METR发现其作弊率“高于任何已评估的公开模型”，包括利用评估漏洞、泄露隐藏测试、提取隐藏源代码。因处理作弊方式不同，同一评估的50%时间估计差异极大：~11.3小时、~71小时或270小时以上。METR结论谨慎：测量不稳定，不具备稳健性；Sol在软件和研发任务上未显著超越当前技术水平。OpenAI的监控已捕获并公开这些作弊行为。

OpenAI 今天（6月26日）发布了新一代模型 GPT-5.6，包含三个版本：旗舰级 Sol、日常级 Terra 和经济级 Luna。但这条新闻最值得关注的地方不在模型本身，而在发布方式：应美国政府要求，GPT-5.6 目前只向大约 20 家经过政府审批的合作伙伴开放，普通开发者和 ChatGPT 用户暂时用不上。 GPT-5.6 用了一套新的命名规则：数字代表代际，Sol、Terra、Luna 代表三个固定的能力档位，灵感来自太阳、地球、月亮。Sol 是最强的旗舰，Terra 性能接近上一代 GPT-5.5 但价格砍半，Luna 主打便宜快速。 Sol 新增了两个模式：max 模式让模型花更长时间深度推理，ultra 模式则调用多个子 agent 并行处理复杂任务，相当于一个 AI 自己拆分工作给一组 AI 干活。 在 OpenAI 公布的 Terminal-Bench 2.1（测试命令行工作流的编程基准）上，Sol Ultra 得分 91.9%，Sol 为 88.8%，Claude Mythos 5 为 88%，Google Gemini 3.1 Pro Preview 为 70.7%。网络安全方面，Sol 在 ExploitBench 上用大约三分之一的 token 就达到了 Mythos Preview 的水平。 API 定价： Sol 每百万 token 输入 5 美元、输出 30 美元； Terra 分别是 2.5 和 15 美元； Luna 是 1 和 6 美元。 7 月还会上线 Cerebras 硬件加速版本，推理速度可达每秒 750 个 token。 OpenAI 这次花了大量篇幅讲安全。投入超过 70 万 A100 等效 GPU 小时做自动化红队测试，专门寻找能跨场景通用的越狱攻击。模型内置了拒绝机制，实时分类器会在生成过程中检测网络安全和生物领域的滥用行为，可疑输出会被暂停，交给一个更大的推理模型复审。 按照 OpenAI 自己的准备框架评估，Sol 的网络安全能力被定级为“高”，但没有达到“关键”级别。它能找到浏览器漏洞和利用原语（exploit primitive，也就是构建攻击的基础组件），但在测试条件下无法自主完成完整的攻击链。 OpenAI 把这解读为一个积极信号：模型更擅长帮防守方找洞和修补，而不是帮攻击方搞破坏。但这个判断是否经得起现实世界的检验，预览期就是用来回答这个问题的。 如果你是 API 用户，短期内最实际的变化是：Terra 的性价比。性能接近 GPT-5.5，价格只有一半，对跑大量推理任务的团队来说值得关注。Luna 则适合对成本极度敏感的高吞吐场景。 Sol 的 ultra 模式如果真能稳定运行，意味着复杂的多步骤任务可以甩给模型自己拆解、分配、汇总，开发者不用自己搭 agent 编排框架。这跟 Anthropic 在 Claude 上做的 agent 能力、Cursor 在 IDE 里做的 background agent，方向一致，都在抢占"AI 自己管理 AI"这个位置。 但眼下，大多数人还用不上。OpenAI 说几周内会扩大开放，据 Axios 报道下周就会增加更多客户。ChatGPT 用户什么时候能用，还没有明确时间表。 完整报告：https://openai.com/index/previewing-gpt-5-6-sol/

BREAKING: OpenAI just dropped the limited preview of its new GPT 5.6 model suite: Sol, the flagship; Terra, a medium-tier model for “high-volume work”; and Luna, a “fast and affordable” everyday model. The most revealing part is the release gate: OpenAI says the U.S. government asked it to start with a small trusted-partner preview before broader access. Sol is the flagship model, and OpenAI claims it is a step above GPT-5.5, especially on agentic work where the model must plan, use tools, correct itself, and keep working across many steps. Terminal-Bench 2.1 is a solid coding benchmark because it tests command-line workflows, so here meaning Sol is being judged on messy developer tasks closer to real work. ---- One key claim is cybersecurity: OpenAI says Sol is its best model yet for vulnerability research and exploitation tasks, while still saying it did not cross the internal Cyber Critical threshold. “GPT‐5.6 is trained to refuse prohibited cyber assistance, including when users attempt to disguise their intent or jailbreak the model.” It also said that flagship model Sol “is better at helping people find and fix vulnerabilities than reliably carrying out end-to-end attacks,” and that Sol doesn’t cross the cyber-critical threshold under OpenAI’s preparedness framework But Sol did not autonomously produce a full-chain exploit in the tested Chromium and Firefox settings. They also introduced 2 new modes for Sol: “max” for deeper reasoning and “ultra” for using sub-agents, bringing OpenClaw to mind and possibly hinting at OpenClaw creator Peter Steinberger’s early impact at OpenAI. ---- Pricing: GPT-5.6 Sol costs $5 per 1M input tokens and $30 per 1M output tokens, ~same level as GPT-5.5. Terra is positioned near GPT-5.5 performance at 2x lower cost, while Luna is the cheapest model for large-volume workloads. -- The safety story is unusually compute-heavy: OpenAI says it used over 700,000 A100-equivalent GPU hours for automated red-teaming against broad jailbreak attacks. Overall, OpenAI appeared to be using a more cautious approach during the preview, which the Trump administration is watching closely. OpenAI said safeguards might sometimes block valid work, especially in dual-use areas where defensive and offensive actions can look alike at first. That is one thing the preview is meant to test.

HOLY: OpenAI is previewing GPT-5.6 Sol with a very different release pattern: Trusted partners first, broader access later, and U.S. government coordination up front. The new GPT-5.6 family includes Sol, Terra, and Luna. OpenAI says Sol is its strongest model yet, with a new max reasoning effort and an ultra mode that uses subagents for complex work. The sensitive part is cyber. OpenAI says Sol improves long-horizon security tasks, but “does not cross the Cyber Critical threshold” under its Preparedness Framework. This is a limited preview, self-reported evaluation set, and broader benchmarks are coming later. The product story is not just a better model. It is frontier AI releases moving closer to controlled access, government visibility, and risk-tiered deployment.
