SynthID watermarking expands partnerships, covering over 100 billion content items

SynthID水印技术扩展合作，覆盖超千亿内容

Google DeepMind says SynthID has watermarked more than 100 billion content items and is being integrated into models from OpenAI, ElevenLabs, and Kakao, extending prior industry work with NVIDIA.

Why it matters: HKR-H/K/R all pass: the story has a >100B usage number and named integrations with OpenAI, ElevenLabs, and Kakao. It is strong provenance infrastructure news, but still a partnership expansion rather than an 85+ must-write release.
