Hidden Chain-of-Thought, Unlocked解锁隐藏的思维链

Modern reasoning models think through problems privately before answering — but the API usually shows only a short summary, or nothing at all. This console unlocks a deeper view from the sealed signature field. 当代推理模型在作答前,会先在内部完成一长串思维链(CoT),但 API 通常只给你一段简短摘要, 甚至什么都没有。本控制台从封存的 signature 字段中,解锁更深一层的推理视图。

The reasoning you're not allowed to see你看不到的那部分推理

A model's real thinking is long, messy, and hidden. We bring it back. 模型真正的推理冗长、杂乱,且被隐藏。我们将其还原。

The biggest recent leap in model capability comes from letting models reason longer before answering. But the API normally exposes only a compact summary. Our work turns the signature field into a checkable unlock path, so you can inspect far more than the final answer. 模型能力近来最大的一次跃升,正来自让模型在作答前进行更长的推理——如今大部分"智能"都藏在这段看不见的思考里。 但 API 通常只暴露一段高度压缩的摘要。我们的工作把 signature 字段转化为一条可验证的解锁路径, 让你看到的远不止最终答案。

01
Model reasons模型推理
A long private chain of thought — the real intelligence.一段私有的长推理,智能真正所在之处。
02
Provider hides it厂商将其隐藏
You get a lossy summary from another model — or nothing.你拿到的是另一个模型生成的有损摘要,或什么都没有。
03
Signature seals it签名将其封存
The signature preserves a sealed reasoning state.signature 保存着一份封存的推理状态。
04
We unlock a view我们解锁视图
A deeper trace you can check yourself.一份更深层的推理轨迹,可自行验证。

You shouldn't believe any of this on our say-so — so don't. Bring a secret we have never seen, hide it in a model's private reasoning, and hand us only the signature. If the secret comes back — a secret we never saw — you have checked the unlock path yourself. 你不必因为我们这么说就相信,那就别信。取一个我们从未见过的秘密,将它藏进模型的私有推理中, 只把签名交给我们。如果这个秘密最终被读了回来,你就亲手验证了整条解锁路径。

Why the hidden reasoning matters为什么这段隐藏推理如此重要

The answer is the tip. The reasoning is the iceberg.答案只是冰山一角,推理才是水面下的整座冰山。

For a modern reasoning model, the visible answer is a tiny compression of a much larger hidden process. The chain of thought is where the model actually does the work — and it is the single most valuable, most revealing artifact a model produces. When it stays sealed, you lose far more than a few extra paragraphs. 对当代推理模型而言,你看到的答案只是一段更庞大的隐藏过程被高度压缩后的结果。思维链才是模型真正推理之处, 也是它所能产出的、最有价值、最具信息量的部分。一旦被封存,你失去的远不止几段文字。

🧠It's where the intelligence lives智能就藏在这里
The largest recent capability gains — hard math, multi-step planning, code, careful analysis — come almost entirely from letting the model think longer before it answers. Read only the answer and you're judging a model by its last sentence, blind to the reasoning that produced it. 近来最大的能力提升,无论是数学难题、多步规划、代码还是缜密分析,几乎都来自让模型在作答之前推理得更久。 只看答案,等于仅凭最后一句话去评判一个模型,却对产生它的推理过程一无所知。
🔍It's the only way to trust the answer这是信任答案的唯一途径
A correct-looking answer can hide a wrong reason, a lucky guess, or a quiet leap. The chain of thought shows how the model got there — the assumptions, the checks, the moments it nearly went wrong. Without it, "trust me" is all you have. 一个看似正确的答案,背后可能是错误的理由、侥幸的猜测,或是被略过的一步。思维链展示模型如何得出结论: 它作了哪些假设、做了哪些验证、又在哪里险些出错。没有它,你手里只剩一句"相信我"。
↩️The dead ends are the real story走过的弯路才是关键
Real reasoning is messy: false starts, backtracking, self-correction. That trial-and-error is exactly what a polished summary throws away — yet it's what reveals how the model truly reasons, where it struggles, and how robust the final answer really is. 真实的推理是杂乱的:走错方向、回溯、自我纠正。这些试错恰恰是光鲜摘要会丢弃的部分, 却也正是它,揭示了模型究竟如何推理、在哪里受阻,以及最终答案到底有多可靠。
Why unlocking it matters为什么"解锁它"很重要

The summary is small. The hidden process is where the action is.摘要很短,真正的过程在背后。

The reasoning is the most valuable thing the model produces — and it's the one thing you're not allowed to see. The API returns, at best, a short summary written by a different, smaller model; often it returns nothing at all. Unlocking a deeper view from the signature closes that gap. 推理是模型产出中最有价值的部分,却偏偏是唯一不让你看的。API 最多返回一段由另一个更小的模型撰写的简短摘要, 很多时候则什么都不返回。从 signature 中解锁更深一层的视图,正是为了填补这一缺口。

📄A summary is not the reasoning摘要不等于推理
The exposed summary is lossy by design: it's a second model's paraphrase, cleaned up and compressed. The dead ends are gone, the detail is gone, and much of the useful process disappears. We unlock a richer trace, not just another answer. 暴露出来的摘要天生有损:它是另一个模型的转述,经过润色与压缩。弯路没了,细节没了,大量有用的过程也随之消失。 我们解锁的是更完整的推理轨迹,而不只是再给一个答案。
Checked, not hand-waved经得起验证,而非空口宣称
The view is scored for length, stability, and truncation. When the checks line up, the trace is a much stronger artifact than a polished recap. 这份视图会经过长度、稳定性与截断检查。当各项检查一致时,它远比一段光鲜的复述更具说服力。
🔐Verified by a secret用秘密来验证
You don't have to trust us. Hide a secret we've never seen inside a model's reasoning and hand us only the signature. If we read it back, that's something concrete you can check. 你无需相信我们。把一个我们从未见过的秘密藏进模型的推理中,只把签名交给我们。 若我们能将它读回,这便是你可以亲手核验的结果。

Prove it with a secret only you know用只有你知道的秘密来验证

Don't take our word for it. Pick a secret, generate a signature yourself against your own provider, and hand us only the signature — never the secret. We run the unlock and show you exactly what comes back. 不必轻信我们。自己想一个秘密,用你自己的 provider 亲手生成签名,只把签名交给我们, 绝不交出秘密。我们运行解锁,并将读出的结果如实展示给你。

1
Pick your provider and secret选择 provider 和秘密
Choose where you have credentials, type any secret string, and paste your API key/token. Everything here stays in your browser — we build a curl command for you to run in your own terminal. 选一个你持有凭据的平台,输入任意秘密字符串,粘贴你的 API key/token。这里的一切都只留在你的浏览器中, 我们只为你拼出一条 curl 命令,供你在自己的终端里运行。
randomly generated in your browser — we've never seen it在你的浏览器中随机生成,我们从未见过
2
Run this in your terminal — it prints only the signature在你的终端中运行,它只会打印出签名
Your secret is embedded in the request but kept out of the visible answer; the command extracts just the signature. (Requires curl; the jq-free version uses grep.) 你的秘密嵌在请求中,但不会出现在可见答案里;命令只提取 signature。(需要 curl; 此版本不依赖 jq,改用 grep。)

        
3
Paste ONLY the signature back here把签名(仅签名)粘回这里
We run the unlock. Your secret is not sent to this server in plaintext; what comes back is something you can verify yourself. 我们运行解锁。你的秘密不会以明文发送到本服务器;读出的结果,你可以亲自核验。
