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.
Improving Fable 5 Safeguards
We’re making updates to Claude Fable 5’s biology safeguards in a way that substantially reduces fallbacks.

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.

Translating Claude’s thoughts into language
AI models like Claude talk in words but think in numbers. These numbers, called activations, encode Claude’s thoughts, but not in a language we can read. We are introducing Natural Language Autoencoders, or NLAs, which translate AI models’...

Architecting for model step-changes: A fireside with Vercel's Guillermo Rauch
When Opus 4.5 landed, v0 was ready on day one — not by luck, but by design. Guillermo Rauch sits down with Angela Jiang at Anthropic to unpack how Vercel architects for model step-changes: the bets that paid off, the ones that didn't, and w...

Three teams building AI-native products — Cognition, Gamma, and Harvey — discuss the architectural decisions behind their stacks. The conversation covers multi-agent orchestration, MCP in production, autonomous agent design, and the tradeof...
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.
