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.<br>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<br>answering. But the API normally exposes only a compact summary. Our work turns the<br>signature field into a checkable unlock path, so you can inspect far more than the final answer.<br>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。<br>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,<br>让你看到的远不止最终答案。

01<br>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<br>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<br>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<br>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,<br>hide it in a model's private reasoning, and hand us only the signature . If the secret comes back —<br>a secret we never saw — you have checked the unlock path yourself.<br>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,<br>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<br>process. The chain of thought is where the model actually does the work — and it is the single most<br>valuable, most revealing artifact a model produces. When it stays sealed, you lose far more than a few<br>extra paragraphs.<br>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,<br>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<br>almost entirely from letting the model think longer before it answers. Read only the answer and<br>you're judging a model by its last sentence, blind to the reasoning that produced it.<br>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。<br>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<br>shows how the model got there — the assumptions, the checks, the moments it nearly went wrong. Without<br>it, "trust me" is all you have.<br>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:<br>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<br>what a polished summary throws away — yet it's what reveals how the model truly reasons, where it struggles,<br>and how robust the final answer really is.<br>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,<br>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<br>to see. The API returns, at best, a short summary written by a different, smaller model ; often it returns<br>nothing at all. Unlocking a deeper view from the signature closes that gap.<br>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,<br>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.<br>The dead ends are gone, the detail is gone, and much of the useful process disappears. We unlock a richer<br>trace, not just another answer.<br>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。<br>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<br>stronger artifact than a polished recap.<br>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<br>the signature. If we read it back, that's something concrete you can check.<br>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。<br>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<br>provider, and hand us only the signature — never the secret. We run the unlock and show you exactly<br>what comes back.<br>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,<br>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。
