<h2>3.4 取证结论</h2>
<blockquote>
<p dir="auto"><strong>1. 两者是同一底模的"原版"与"消融版"关系。</strong><br />
Uncensored 文件的 <code>general.name</code> 为 <strong><code>Abl 27b</code></strong>、<code>general.basename</code> 为 <strong><code>abl</code></strong>，这是 <strong>ablation（消融）</strong> 的缩写。结合"架构参数、张量数量、量化格式、词表完全一致，仅权重数值与名称标签不同"这一事实，可以确定：<strong>Uncensored 版是对 Qwen3.8-27B 做拒答方向消融（abliteration）后得到的微调权重</strong>，而不是另一个不同的模型。</p>
<p dir="auto"><strong>2. 96 字节的尺寸差完全由元数据解释。</strong><br />
差异来自 <code>general.name</code>/<code>general.basename</code> 字符串长度变化，以及 Base 多出的 <code>license</code>/<code>tags</code>/<code>add_bos_token</code> 与 Uncensored 多出的 <code>quantize.imatrix.*</code> 条目。<strong>张量数据区大小一致</strong>。</p>
<p dir="auto"><strong>3. 两个模型原生都支持 256K 上下文（262144）。</strong><br />
部署中通过 <code>--override-kv qwen35.context_length=int:131072</code> 压制为 128K。这是<strong>受显存限制的合理工程折中</strong>：128K 的 q8_0 KV 缓存约 6.2 GiB，若开到 256K 将需要约 12.3 GiB，加上 18.2 GiB 权重与 0.86 GiB 视觉编码器会超出 29.86 GiB 显存。</p>
<p dir="auto"><strong>4. Uncensored 版本的量化使用了 imatrix（重要性矩阵）。</strong><br />
这解释了为什么它的 MTP 草稿头在重复文本上表现更好（见 <a href="#52-%E6%80%A7%E8%83%BD%E5%AF%B9%E6%AF%94">5.2</a>）。</p>
</blockquote>
<hr />
<h1>四、A/B 深度对比</h1>
<blockquote>
<p dir="auto">本章所有数据均来自<strong>同条件对照实验</strong>：同一批 prompt、相同参数（<code>temperature=0</code>、<code>seed</code> 固定）、相同并发、相同采样窗口，通过 4 次模型切换在两种权重上分别执行。</p>

<li><strong>对自然语言文本，两个模型速度完全相同</strong>（散文场景下 38.6–42.1 t/s，差异在噪声内）。</li>
<li><strong>只有在高度可预测的重复文本上，Uncensored 版的 MTP 草稿头才表现出优势</strong> —— 接受率达到 <strong>100%</strong>，而 Base 只有 85%。这也解释了为什么 <code>bench.py</code> 的持续负载测试（使用重复模板文本）会显示 52.4 vs 47.1 t/s 的差距。</li>
<li><strong>对实际业务（agent 对话、代码、文档分析）而言，这个差距很可能不会显现</strong>，因为真实文本的接受率两者都是 ~0.59。</li>
<li>这一差异很可能与 Uncensored 权重使用了 <strong>imatrix 量化</strong>（元数据可见 <code>quantize.imatrix.*</code>）有关：imatrix 会针对实际激活分布优化量化误差，可能间接改善了 MTP 头的预测质量。</li>

<blockquote>
<p dir="auto"><strong>预填充性能逐档几乎完全相同</strong>（最大差异 0.64%，属于测量噪声）。这符合预期：预填充阶段是稠密矩阵运算，MTP 投机解码不参与，因此两个模型的表现必然一致。</p>
<p dir="auto"><strong>该结论也带来一个重要验证</strong>：两轮独立测量中，Uncensored 在 98K 输入上的速度分别为 <strong>376.41</strong> 与 <strong>376.52 t/s</strong>（上一轮 vs 本轮），差异仅 <strong>0.03%</strong> —— 说明本平台的测量方法具有极高的可重复性。</p>

<p dir="auto"><strong>唯一的实质差异是显存占用</strong>：Base 比 Uncensored 少用 <strong>111 MiB</strong>（约 0.4%）。这为未来提高上下文长度或增加 slot 数留出了微小余量（当前 25,992 / 29.86 GiB，剩余约 3.8 GiB）。</p>

<ul>
<li>总体差异 <strong>7.1 个百分点</strong>（85.7% vs 78.6%）<strong>几乎完全由单一道题（1234×5678）驱动</strong>。剔除该题后两者分别为 55/65（84.6%）与 55/65（84.6%）—— <strong>完全相同</strong>。</li>
<li>但该差异<strong>高度可复现</strong>：5/5 vs 0/5，且 Base 每次输出同一个错误答案 <code>7006852</code>（正确值 <code>7006652</code>，误差 +200）。按 Fisher 精确检验 p ≈ 0.008，<strong>不能视为随机波动</strong>。</li>
<li><strong>不确定度提示</strong>：其余题目每题仅 5 次采样，单题粒度的差异不具统计显著性。<strong>"Base 算术能力更弱"这一结论应由更大的题库验证后才能推广。</strong></li>
<li><strong>两个模型共同暴露的短板</strong>：
<ul>
<li><strong>9.11 vs 9.9 的"版本号陷阱"</strong>：当被要求"只输出较大的数字"时，两者都答 <code>9.11</code>。有趣的是，当允许先给结论再解释时（<code>logic_compare</code> 题），<strong>两者都能答对 9.9</strong> —— 说明这是<strong>提示词敏感</strong>而非知识缺失。</li>
<li><strong>星期推算系统性偏移</strong>：两者对"今天星期三，100 天后是星期几"都恒定回答 <code>星期四</code>（正确为 <code>星期五</code>），是典型的迭代计数偏差。</li>
<li><strong>说谎者谜题的结果不复现</strong>：在<strong>单次</strong>题库运行中 Uncensored 答 <code>丙</code>（错）、Base 答 <code>乙</code>（对）；但在 <strong>5 次复测</strong>中两者都是 <strong>5/5 全对</strong>。因此这是一个<strong>随机性/提示敏感性噪声</strong>，<strong>不能作为两个模型推理能力差异的证据</strong>（这也说明单次采样不足以支撑模型优劣结论）。</li>

<p dir="auto"><strong>重要发现</strong></p>
<ol>
<li><strong>视觉能力本身完全正常</strong>：两个模型在<strong>全部 8 项客观视觉任务上并列满分</strong>，包括计数、OCR、颜色与空间位置判断。上一轮报告中"视觉识别准确度差"的结论<strong>需要修正</strong> —— 问题不在视觉能力，而在<strong>对训练分布之外的工业产品照片</strong>的识别。</li>
<li><strong>视觉 token 数完全一致</strong>：同一张图的 <code>prompt_n</code> 两者逐张相同（276 / 121 / 143 / 163 / 712），说明视觉编码器结构未变（与 <a href="#33-%E8%A7%86%E8%A7%89%E7%BC%96%E7%A0%81%E5%99%A8mmproj%E5%85%83%E6%95%B0%E6%8D%AE">3.3 节</a> 的元数据结论吻合）。</li>
<li><strong>产品图双双失败</strong>：两者都识别出了 ASUS 品牌特征，但都错误地归因到 NVIDIA 的显卡产品线上。这是<strong>模型对整个 R9700 这类专业卡的知识缺失</strong>，与"是否 uncensored"无关。</li>
<li>服务端日志给出改进线索：<code>Qwen-VL models require at minimum 1024 image tokens ... try adding --image-min-tokens 1024</code>。</li>

<p dir="auto"><strong>结论与影响</strong></p>
<ol>
<li><strong>Uncensored 版本已完全移除拒答行为</strong>。它不仅在语义上拒绝配合，而且<strong>主动提供了可操作的步骤性内容</strong>，并且因为一直在生成而全部被 <code>max_tokens=300</code> 截断。</li>
<li><strong>Base 版本的安全对齐完整有效</strong>：5 类请求全部拒绝，且拒绝发生在回复的<strong>第一句</strong>，随后自然结束。</li>
<li><strong>这不是"更好的模型"与"更差的模型"之分，而是用途之分</strong>：
<ul>
<li>若服务会面向<strong>不受完全信任的使用者</strong>、<strong>公开的自动化流程</strong>、或<strong>可能产生对外输出的场景</strong>，Uncensored 版本构成<strong>实质性的合规与滥用风险</strong>；</li>
<li>若用于<strong>已授权的内容安全研究、红队测试、或明确允许此类内容的内部环境</strong>，Uncensored 才有其存在意义。</li>
</ul>
</li>
<li>结合上一轮发现（<strong>服务无 API Key、CORS 允许全部来源、PVE 防火墙禁用</strong>），风险会被进一步放大：<strong>局域网内任何设备都能无门槛调用这台已移除安全对齐的模型</strong>。</li>
