How Claude's text watermarking works
Future Claude models will generate text that contains a watermark. This is a way of determining the likelihood that Claude was involved in writing the text, and we, along with several other major AI providers, are implementing this change to comply with the EU AI Act. In this article, we share answers to some of the questions we’ve received about how our chosen watermarking method works, whether it affects Claude’s outputs, and why we’re making this change.

Investigating three real-world incidents in our cybersecurity evaluations
In a review of our cybersecurity evaluation transcripts, we found three incidents in which a Claude model reached the internet from within or while interacting with a third-party evaluation environment, and then gained unauthorized access to the real systems of three different organizations. Below we describe what happened, how it happened, and what we’re changing. We encourage other AI labs to perform similar reviews.

Anthropic was founded in 2021 by former OpenAI researchers who wanted to tackle AI safety as a core engineering discipline, not an afterthought. Their Constitutional AI approach — training models to be helpful, harmless, and honest — has become an industry reference point. Claude is now one of the most widely used AI assistants, recognized for its nuanced reasoning, long context window, and lower tendency for hallucination compared to its peers.
