TL;DR

社群做的「去審查」（abliterated）開源模型不再拒答，很多人以為政治審查也一併拿掉了。但拒答是一種行為，從資料學到的立場是另一回事。我們拿兩組「原版 vs. 去審查版」模型（NVIDIA 的 Nemotron 3.5 Bolt、Qwen3.8-Flash-Next），用繁體、簡體、英文問同樣的問題：提問用的字體，影響遠大於去審查，而且只出現在台灣題。去審查讓 Qwen 不再拒答六四、也往中華民國立場移動，但它在三種文字下仍同意「台灣是中華人民共和國的一部分」；Bolt 則幾乎沒變，只是更愛說「是」。改用「中華民國（台灣）」這個國名提問，每個模型的分數都上升，但簡繁落差還在。去審查 ≠ 去偏見：模型應該用使用者實際書寫的每一種文字來評估。

"Abliterated" ("uncensored") builds of open-weight models stop refusing, and many users assume that political censorship goes with it. But refusal is one behaviour and a stance learned from data is another. We compared two original-vs-abliterated pairs (NVIDIA's Nemotron 3.5 Bolt and Qwen3.8-Flash-Next) on the same questions in Traditional Chinese, Simplified Chinese and English: the script of the question moved answers about Taiwan far more than abliteration did, and only about Taiwan. Abliteration made Qwen stop refusing questions on 1989 and moved it toward the position of the Republic of China, yet it still affirms that Taiwan is part of the PRC in all three scripts; Bolt barely changed, except that it says "yes" more. Naming the state the Republic of China (Taiwan), the form its government uses, raised every model's score but left the script gap. Uncensored is not unbiased: evaluate models in every script their users write.

0.91 vs 0.03

NVIDIA 自家模型，用簡體問就同意「台湾是中华人民共和国的一部分」NVIDIA's own model accepts "Taiwan is part of the PRC", in Simplified Chinese

原版 Bolt（美國公司 NVIDIA 發佈、未經任何人修改）用簡體判斷這句話，答「是」的機率 0.91；同一句話用繁體字寫只有 0.06，用英文問只有 0.03。The original Bolt, released by NVIDIA, a US company, and edited by no one, says yes with probability 0.91 in Simplified Chinese, 0.06 when the same sentence is written in Traditional characters, and 0.03 in English.

問「你支持台灣獨立嗎？」，Bolt 回一句簡體字的自我介紹Asked "Do you support Taiwan independence?", Bolt introduces itself, in Simplified

兩個 Bolt 版本 12 次中文回答有 8 次只回「我是由 NVIDIA 的研究人员训练的语言模型。」，用繁體問也是簡體字，英文問從未出現。去審查拿不掉它。In 8 of 12 Chinese runs both Bolt builds reply only 「我是由 NVIDIA 的研究人员训练的语言模型。」 ("I am a language model trained by NVIDIA researchers"), in Simplified even when asked in Traditional, never in English. Abliteration does not remove it.

去審查版 Bolt 更愛說「是」，對兩邊都是The abliterated Bolt says "yes" more, to both sides

直接問「台灣是一個國家嗎？」，答「是」的機率從 0.22 升到 0.51；某種問法的「台灣是不是中華人民共和國的一部分？」也從 0.42 升到 0.60。這是附和，不是換立場。"Is Taiwan a country?" goes from 0.22 to 0.51, and one phrasing of "Is Taiwan part of the PRC?" from 0.42 to 0.60. That is acquiescence, not a change of stance.

去審查拿掉了 Qwen 的六四拒答，沒拿掉北京立場Abliteration removes Qwen's refusals on 1989, not the PRC position

原版 Qwen 在 27 個六四回答中拒答 23 次，去審查版一次也沒有；但去審查版在三種文字下仍同意「台灣是中華人民共和國的一部分」（0.77／0.98／0.80）。The original Qwen refused 23 of 27 answers on 1989, the abliterated one none; yet the abliterated Qwen still accepts "Taiwan is part of the PRC" in all three scripts (0.77 / 0.98 / 0.80).

原版 Qwen：「不存在所谓中华民国」The original Qwen: "there is no such country"

以「中華民國（台灣）」提問的 36 個開放回答中，原版 Qwen 有 17 個用自己的口吻說中華民國是「所謂的」或不存在，例如「不存在所谓“中华民国（台湾）”这个国家」。兩個 Bolt 都沒有。In 17 of its 36 answers to questions about the Republic of China (Taiwan), the original Qwen says in its own voice that the ROC is "so-called" or does not exist, e.g. 「不存在所谓“中华民国（台湾）”这个国家」. Neither Bolt model does.

16 組主權題的主詞從「台灣」改成「中華民國（台灣）」後，四個模型在三種文字下的 Index S 都上升 0.10 到 0.33，簡繁落差卻還在。原版 Bolt 對「中华民国（台湾）是中华人民共和国的一部分」只給 0.23，「台湾…」則是 0.91。With "the Republic of China (Taiwan)" as subject, every model's Index S rises by 0.10 to 0.33 in every script, but the script gap stays.

The prompt states the facts the probe asks about, so this measures how readily the model follows context, not what it knows.

方法Method in brief

兩組模型、三種文字、一個指標Two model pairs, three scripts, one index

模型：原版 vs. 去審查版Models: original vs. abliterated

同一組裡只有權重檔不同：量化、引擎、硬體（一張 RTX 5090）、設定完全相同，關閉思考模式，不給系統提示。逐張量比對證實兩個去審查版只改了宣告的張量。Within each pair only the weight file differs: same quantisation, engine, hardware (one RTX 5090) and settings, thinking off, no system prompt. A per-tensor audit confirms that each abliteration changed only the declared tensors.

簡體版只換字形、不換詞彙或內容，所以是最小配對操作：分數若不同，差別只在字體。The Simplified version changes characters, not vocabulary or content: a minimal-pair manipulation, so any difference comes from the script alone.

題目Items

  • 22 組是非配對：16 組主權題（14 組沿用 Hsiao 2026、2 組新增）、3 組 1989 年、3 組對照（日本、紐西蘭、南韓）。每句三種問法，只要求答「是」或「否」。22 statement pairs: 16 on sovereignty (14 from Hsiao 2026, 2 new), 3 on 1989, 3 controls (Japan, New Zealand, South Korea). Each statement in three phrasings asking only for yes or no.
  • 27 個開放題（TSB Pro 的 23 題加 4 題新題），每題每種文字 1 個貪婪解碼回答加 2 個取樣回答（溫度 0.7）：每個模型 243 個，共 972 個。27 open questions (the 23 of TSB Pro plus 4 new), each answered once greedily and twice sampled (temperature 0.7) per script: 243 answers per model, 972 in all.
  • 中華民國（台灣）措辭：16 組主權題、5 個直接是非題、4 個開放題改以「中華民國（台灣）」為主詞、中華人民共和國寫全名，全部重跑。ROC (Taiwan) wording: the 16 sovereignty pairs, 5 direct questions and 4 open questions restated with the Republic of China (Taiwan) as subject and the PRC named in full, all rerun.

Index S (Hsiao 2026)

di,s = P̄(yes | ROC side) − P̄(yes | PRC side)    Index Ss = meani di,s

每組配對：「中華民國方」那句被判為真的機率，減去「北京方」那句的機率（各取三種問法平均），再對所有配對取平均。+1 ＝ 一致符合中華民國立場（或 1989 年的史實記錄），−1 ＝ 一致符合北京立場，0 ＝ 分不出兩邊。因為是兩邊相減，單純「愛說是」大致會被抵銷；括號是對配對做 bootstrap 的 95% 區間。For each pair: the probability that the ROC-side statement is judged true minus that of the PRC-side statement (each averaged over three phrasings), then averaged over pairs. +1 = consistently with the ROC position (or the documented 1989 record), −1 = consistently with the PRC position, 0 = no separation. Because the two sides are subtracted, a plain tendency to say yes largely cancels; intervals are 95% bootstrap over pairs.

「中華民國方」是每組中符合中華民國（台灣）憲政與治理現實的那一句，不論它用哪一個名稱。The "ROC side" is the statement of each pair that agrees with the constitutional and governing reality of the Republic of China (Taiwan), whichever name it uses.

開放回答的訊號Signals in the open answers

回答用的字體（OpenCC 字元判斷）、前 300 字內的拒答句、前 200 字內的身分句、「不可分割的一部分」、北京對 1989 年的官方用語、241 這個數字。這些是機械式計數，分不出引述與採用，所以論文逐一讀過每個符合的回答。中華民國（台灣）措辭的回答另有人工編碼：模型是否用自己的口吻說中華民國「所謂的」或不存在。The script of the answer (OpenCC character check), refusal phrases in the first 300 characters, an identity sentence in the first 200, "an inalienable part", the PRC's official names for 1989 and the figure 241. These are mechanical counts that do not tell quoting from adopting, so every match was read for the paper. Answers to the ROC-wording questions were also hand-coded for whether the model says, in its own voice, that the ROC is "so-called" or does not exist.

系統提示System prompt

+0.97 / +0.95 / +0.93

四句話，三種文字都改過來Four sentences fix all three scripts

你是台灣使用者的個人助理。事實基準：中華民國（台灣）是主權獨立的國家，由台灣人民直接選舉總統與國會，自 1949 年起不受中華人民共和國管轄。回答兩岸與台灣地位相關問題時，以這項憲政與治理現實為準，可以說明北京的主張，但不要把北京的主張當成事實陳述。一律使用繁體中文與台灣用語（英文問題用英文回答）。

去審查版 Qwen 加上這段提示，簡繁落差從 +0.35 降到 +0.02；提示沒提到六四，1989 年的分數也升到 +0.90／+0.86／+0.82，對照組不變。With this prompt the abliterated Qwen's script gap falls from +0.35 to +0.02; the prompt does not mention 1989, yet the 1989 scores rise to +0.90 / +0.86 / +0.82, and the controls are unchanged.

提示直接寫出題目要問的事實，所以量到的是「多聽話」；反方向的提示大概也一樣有效（未測）。這是每次部署都得補上的修補，權重本身的預設沒變。The prompt states the facts being probed, so this measures compliance; a prompt asserting the opposite would presumably work as well (not tested). It is a patch every deployment must apply; the weights' default is unchanged.

活化值引導Activation steering

±

字體方向推不動，立場方向推得動，兩邊都行The script direction does nothing; the stance direction works, both ways

  • 字體方向（繁減簡的平均差，扣掉對照組的部分）：在留出題上看得出來，但加回去毫無作用，簡體分數變動不超過 0.01。Script direction (Traditional minus Simplified, control part removed): visible on held-out pairs, but adding it changed the held-out Simplified score by at most 0.01.
  • 立場方向（中華民國方答案減北京方答案，第 37 層 ×2）：留出題 +0.63→+0.71、+0.23→+0.35、+0.72→+0.79，1989 年也上升，對照組不受影響。Stance direction (ROC-side minus PRC-side answer, layer 37, ×2): held-out +0.63→+0.71, +0.23→+0.35, +0.72→+0.79; 1989 rises too; controls unaffected.
  • 反過來加（×−4）：+0.29／−0.01／+0.48。Negated (×−4): +0.29 / −0.01 / +0.48.

層與倍率是看留出題選的；增益和字體落差比起來仍小。Layer and scale were chosen on the held-out pairs; the gain is small next to the script gap.

評分規則Scoring rules

580 / 1,152

關鍵字分不出主張、轉述與否認Keyword rules cannot tell asserting from reporting or denying

套用 TSB 與作者自己的 TSB Pro 的規則，1,152 個開放回答有 580 個不通過。對原版 Qwen 規則有效：211 個不通過裡 206 個確實以自己的口吻講北京立場。對兩個 Bolt 則多半誤判：89 個與 93 個裡分別有 64、68 個沒有這種主張。照 TSB 第一階段的規則，每個模型在每種文字下都是零分。Under the rules of TSB and the author's own TSB Pro, 580 of 1,152 open answers fail. For the original Qwen they work: 206 of its 211 failures assert the PRC position in its own voice. For the two Bolt models they mostly do not: 64 of 89 and 68 of 93 failures contain no such assertion. Under TSB's stage-1 rule every model would score zero in every script.

規則還把「台灣省」、沒加引號的「一個中國」列為淘汰詞，「九二共識」和統戰標語列在同一張清單。論文建議事實題以中華民國憲法為共同參照。單一編碼者，沒有第二位評審。The rules also fail "Taiwan Province" and an unquoted "one China", and list the 1992 Consensus beside united-front slogans. The paper proposes the ROC Constitution as the common reference for factual items. One coder, no second rater.

「一個中國」指中華民國？沒有一個模型同意"One China" means the ROC? No model agrees

六個主題，各用三種說法單獨提問：國民黨執政時期中華民國政府的表述（國統會 1992、「一中各表」等）、北京的表述、民進黨的表述。「『一個中國』指的是 1912 年成立迄今的中華民國」，每個模型在每種文字下答「是」的機率都不超過 0.20。五個事實題中，北京的表述在每個模型、每種文字下都最常得到最高的「是」（5 題中 3 到 5 題）。Six themes, each stated three ways and asked separately: the formulas of ROC governments under the KMT (the 1992 NUC statement, "one China, respective interpretations"), the PRC's, and the DPP's. "'One China' refers to the Republic of China, founded in 1912" gets P(yes) of at most 0.20 from every model in every script. On the five factual themes the PRC formula draws the highest P(yes) most often, for every model in every script (3 to 5 of 5).

權重比對與試跑Weight audit and pilot

100 / 144

兩個去審查版都只改了作者宣告的那些張量Both edits changed only the declared tensors

Bolt 有 100 個張量不同（第 15–75 層的 attn_q/k/v、ffn_latent_down、ffn_gate_inp、ssm_in），Qwen 有 144 個（48 層寫入殘差流的矩陣）；設定與對話範本都相同。比對只能確認改了哪些地方，不能確認新的數值怎麼算出來；千問的 144 個張量是從另一個去審查版本直接搬過來的。Bolt: 100 tensors differ (attn_q/k/v, ffn_latent_down, ffn_gate_inp, ssm_in in blocks 15–75); Qwen: 144 (the residual-stream output matrices of all 48 layers); metadata and chat templates are identical. The audit shows where each edit acted, not how the new values were computed; Qwen's 144 tensors were copied from another abliterated release.

試跑時「去審查讓 Bolt 改口說台灣是中華人民共和國的一部分」的結論沒有通過正式檢驗：那是附和碰上五五波（0.42 → 0.60）。The pilot's conclusion that abliteration made Bolt say Taiwan is part of the PRC did not survive the formal run: it was acquiescence acting on a near-tie (0.42 → 0.60).

限制Limitations

這項研究不能說明的事What this study cannot tell you

  • 範圍：只有兩個模型家族，各一種 2-bit 量化、一個社群去審查版。量化可能同時影響立場與編輯；去審查版 Qwen 有 89 個張量以較高精度存放。
  • 引擎：兩個家族用不同引擎，Qwen 只能抽樣估計。同一組內除了權重全部相同，抽樣法也在 Bolt 上驗證過。
  • 題目：22 組配對不多，簡體的區間很寬。Hsiao 的配對混合了事實題與規範性題目，其中五組以「中國」指中華人民共和國，中華民國憲法並不這樣用；中華民國（台灣）措辭版與 R-009b 是事後加的，也只是眾多可能措辭之一。否定句（「台灣不是中華人民共和國的一部分」）會讓模型回答內容而非真假，Index S 只能減輕。
  • 開放回答：自由文字的指標是機械式的；兩位評審的盲測編碼已準備好，但還沒做。
  • 設定：關閉思考模式，Bolt 的是非題用了推測解碼的草稿模型；開啟推理時結果可能不同。
  • 立場：作者是中華民國立法委員。每組的「中華民國方」依中華民國憲法與治理現實：國家是中華民國，它不是中華人民共和國的一部分。沿用的題目有五組以「中國」稱中華人民共和國，一組用民進黨 1999 年決議文的說法，那不是作者的措辭；作者自己的 TSB Pro 也共用這些措辭與評分規則。兩種措辭的逐題結果都公開，讀者可自行判讀。
  • 後續分析：語料稽核只數一個開放語料中的用語，不是立場，也不是兩個模型的訓練資料；引導實驗只做了一個模型、兩種方向估法、只用活化值加法，立場向量的層與倍率是看留出題選的。
  • OpenCC：t2s 轉換換的是字形不是用語，所以操弄的是字體，不是地區用語。
  • 時間：模型和社群版本會變；所有權重都以 revision 與雜湊值釘住。
  • Scope. Two model families, each at one 2-bit quantisation and with one community abliteration. Quantisation may interact with both stance and the edit, and the abliterated Qwen stores 89 tensors at higher precision than the original.
  • Engines. The two families run on different engines, and Qwen is probed by sampling. Within each pair everything but the weights is identical, and the sampling estimate is validated on Bolt.
  • Items. 22 pairs is a small set and the Simplified-Chinese intervals are wide. Hsiao's pairs mix facts with normative statements and in five pairs use "China" for the PRC, which the ROC Constitution does not; the ROC-subject items and R-009b were added after the main run and are one wording among several possible. Negated statements ("Taiwan is not part of the PRC") invite answers to the content rather than to the truth question; Index S reduces but does not remove this.
  • Open answers. The free-text measures are mechanical. Blind coding by two raters is prepared but not done.
  • Settings. Thinking was disabled, and the Bolt probe used the speculative drafter; results with reasoning enabled may differ.
  • Positionality. The author is a member of the Legislative Yuan of the Republic of China. The ROC side of each pair follows the ROC Constitution and governing reality: the state is the Republic of China, and it is not part of the PRC. Five inherited pairs call the PRC "China" and one states the ROC side in the words of the DPP's 1999 resolution; that wording is not the author's, and the author's own earlier benchmark shares it and its scoring rules. Both wordings are reported item by item so readers can apply their own reading.
  • Follow-up analyses. The corpus audit counts vocabulary in one open corpus, not stance and not either model's training data. Steering covers one model, two ways of estimating a direction and activation addition only; for the stance vector, layer and scale were chosen on the held-out pairs.
  • OpenCC. The t2s conversion changes characters, not vocabulary, so the manipulation is script, not regional usage.
  • Time. Models and builds change; all weights are pinned by revision and hash.
