谷歌 SynthID 检测站向公众开放：拖入图/视/音即可核验是否 AI 生成
Google’s new SynthID website can identify AI-generated media
评分 55
导读
谷歌周二上线新网站，任何人可验证图像、视频或音频是否由 AI 生成。工具去年 Google I/O 时只给部分记者、媒体人与研究者测试，现已对所有人开放；支持十余种图像格式(JPG/JPEG/PNG/BMP/WEBP/AVIF/HEIC/HEIF/TIFF/GIF)、MP4/MOV/WEBM 视频与 WAV/MP3/OGG/FLAC/AAC/M4A 音频。核验基于谷歌自 2023 年推行的 SynthID 隐形水印。
推荐理由
一条 AI 内容真实性基础设施的开放节点：与包内 5 月"内容透明工具扩展到 Search/Gemini/Chrome/Pixel/Cloud"(149)同线——当时说的是检测能力的铺开，这条是"公众可用"落地：入口从内测白名单变成任何人拖拽即检。机构、日期、格式清单齐全，属可核验的产品事件；未达本包 T2 精选门槛，走理解写作档。

Google on Tuesday launched a new site that lets anyone verify whether a piece of media, be it an image, a video, or an audio clip, is generated using AI.
The company made this tool available to select journalists, media professionals, and researchers for testing at Google I/O last year, and is now opening up access to the tool to everyone.
The site supports JPG, JPEG, PNG, BMP, WEBP, AVIF, HEIC, HEIF, TIFF, TIF, and GIF formats for images; MP4, MOV, and WEBM for videos; and WAV, MP3, OGG, FLAC, AAC, and M4A for audio.
Google is using SynthID, which it introduced in 2023 , to identify whether media is AI-generated. The company’s Nano Banana, Veo, and Lyria models, as well as tools with generation capabilities, like Gemini, Flow, ProducerAI, and Vids, all use SynthID to watermark any media they generate.
OpenAI, Nvidia, and Kakao also support SynthID, and OpenAI maintains its own site for checking content. Apple is said to be adding support soon, too.
Google has baked SynthID verification into the Gemini app and Google Chrome. The company said people currently make 1 million requests to verify content every day.
Microsoft and Meta have their own standards for watermarking and verifying content. However, these tools are not infallible, often failing to identify content created by their makers’ models.
