EU AI Act

Anthropic is embedding a statistical watermark in Claude's text output, based on Google's SynthID-Text method, to comply with EU AI Act rules. Critics argue the technique degrades word choice quality, while legal analysts warn it could create new disclosure headaches for law firms.

Anthropic published a blog post explaining the mechanics of its planned watermarking system for Claude, which uses Google DeepMind's SynthID-Text approach. The move is required under the EU AI Act's Transparency Code and has triggered user backlash on Reddit and X.

Anthropic has begun watermarking text and images generated by Claude to comply with EU AI transparency regulations. The method embeds an undetectable pattern during word selection that can be decoded via API, without affecting output quality, speed, or cost.

Anthropic is rolling out a watermark detection API that lets third-party developers check whether text was generated by Claude. The move stems from EU AI Act compliance requirements and uses a variant of Google DeepMind's SynthID Text method.

Anthropic has begun embedding invisible watermarks in Claude's text outputs to comply with the EU AI Act's Transparency Code. The move has triggered backlash from some users worried the watermarks will expose their undisclosed use of AI at work or in school.

Anthropic is adding machine-readable watermarks to Claude-generated text and digital signatures to generated files to comply with the EU AI Act's Article 50 transparency mandate. The change applies to models launched after Aug. 2 and rolls out globally, though Anthropic admits detection can fail on heavily edited or short text.

Anthropic confirmed it will watermark AI-generated text and files from Claude models, complying with the EU AI Act's Transparency Code that took effect August 2. The watermark is applied at the model level and persists through copy-paste, according to the company.

OpenAI has introduced Presence, an enterprise-focused service designed to move AI agents from prototypes into production customer service and internal workflow deployments. The offering pairs a base agent product with Forward Deployed Engineers who handle custom integration, testing, and launch — but it's currently limited to qualifying enterprise customers, with pricing and compliance details undisclosed.

Anthropic is restricting access to Claude Mythos Preview, a model the company claims can find security vulnerabilities better than most humans, to 52 technology partners. While the UK's AI Security Institute has already tested Mythos and published findings, most European cybersecurity agencies have limited or no access, revealing a structural gap in Europe's AI safety evaluation capacity.
