Anthropic has begun inserting hard-to-detect watermarks into outputs from some Claude models, raising concerns over copyright and privacy. The watermark can remain after copy-and-paste and may persist after edits, and Anthropic says it is meant to distinguish human and AI writing. Critics warn the company could act as sole arbiter, while developers question impacts on text quality and on lightly edited human writing. Anthropic says it will provide a free API and that the mark indicates processing, not authorship.

EU Battery Regulation requirements are entering an implementation phase as the shipment gap between South Korea’s top three battery makers and CATL widens in Europe. From Aug. 18, exporters to the EU must provide a general information label and QR code with details such as manufacturer data, plant location, weight, capacity and hazardous substances. Requirements will expand to carbon footprint grades, supply-chain due diligence, recycled content documents and battery passports, increasing compliance burdens on materials and parts suppliers.
