  "summary": "Major providers of frontier models, including Anthropic, Google, and OpenAI, have adopted watermarking technology to comply with the EU AI Act Article 50, which took effect on August 2, 2026. This regulatory measure mandates that providers of general-purpose and generative AI systems mark synthetic outputs in a machine-detectable format. The compliance shift centers on statistical token-sampling watermarking for natural language generation, where generation runtimes partition model vocabularies into pseudorandom green and red token sets, adding a slight positive bias to the logits of green-listed candidates. This method maintains semantic coherence and inference latency while embedding a mathematically detectable signature across token sequences. Google integrated its Google SynthID framework into Gemini production infrastructure and open-sourced text watermarking implementations for Hugging Face runtimes. OpenAI's Provenance initiatives embed cryptographically signed C2PA metadata manifests into image headers alongside SynthID pixel watermarks, while Meta AI Transparency efforts apply both C2PA metadata and deep-learning image watermarking across consumer endpoints.",
