Major Frontier Model Providers Adopt Watermarking Tech to Comply with EU Regulation
August 2 deadline just passed: major AI vendors now required to watermark all synthetic text under EU AI Act Article 50. Here's what it means for your compliance roadmap.
Why it matters
EU regulation is forcing real technical changes at scale across frontier labs and open-source ecosystems. Practitioners deploying in EU markets need to understand watermarking implementation, performance trade-offs, and emerging vulnerability surface.
The key facts
