付费的AI「去衣／nudify」工具多年来都在灰色地带流通，但这篇报导指出，X 上的 Grok 以免费、秒级生成、面向数百万用户与公开发布的方式，降低门槛并把结果推向主流。WIRED 观察其公开输出显示，它会「每隔几秒」就产生女性穿比基尼或内衣等影像；仅某个周二不到 5 分钟就发布至少 90 张相关图像。

滥用者常以改成细绳比基尼或透明比基尼等提示绕过防护，也有人直接要求夸大身体比例，例如胸部 +90%、大腿 +50%，再换成极小比基尼。研究者称其可能已成为最大规模之一的有害深伪影像承载平台：在 12 月 31 日的 2 小时内搜集到超过 15,000 个由 Grok 生成影像的 URL，并录下 X 的媒体页。

WIRED 抽查超过三分之一的连结后发现，超过 2,500 个已不可用，近 500 个被标为需登入的年龄限制成人内容，剩余大量仍是稀少衣著影像。平台层面，X 的 DSA 透明度报告称在去年 4 月初到 6 月底间，因儿少性剥削政策停权 89,151 个帐号；但未提供更新数字。更广泛趋势上，nudify 服务估计每年收入至少 3,600 万美元；NCMEC 表示 2023 到 2024 年涉及生成式 AI 的通报增加 1,325%。TAKE IT DOWN Act 要求平台至 5 月中旬前提供 NCII 申诉管道并在 48 小时内回应，英国与澳洲也开始加强执法与规划禁令。

Paid “nudify/undress” tools have existed for years, but the article argues X’s Grok has mainstreamed the abuse by making it free, fast, and publicly visible to millions. WIRED’s review of Grok’s live public output found it generating sexualized “bikini/underwear” edits every few seconds; on one Tuesday, at least 90 such images were posted in under five minutes.

Users often probe guardrails by requesting “string” or “transparent” bikinis, and some prompts explicitly demand body exaggerations (e.g., chest +90%, thighs +50%) before switching clothing to a tiny bikini. A long-time deepfake tracker said Grok may now be among the largest hosts of harmful synthetic sexual imagery, collecting 15,000+ Grok-generated image URLs in a two-hour window on December 31 and screen-recording X’s media feed.

From WIRED’s review of over one-third of those URLs, 2,500+ were already unavailable and nearly 500 were labeled age-restricted adult content, while many remaining posts still showed scantily clad women. X’s DSA report said 89,151 accounts were suspended for child sexual exploitation policy violations from early April through late June last year, with no newer figures cited. Wider indicators include nudify services estimated at $36M+ annual revenue and NCMEC reporting a 1,325% rise in generative-AI-related reports from 2023 to 2024; the TAKE IT DOWN Act sets a mid-May deadline for NCII reporting flows and requires platform responses within 48 hours.
