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.

The Problem Solvers: Michele Catasta at Replit
At 16, Michele Catasta set out to make software open to everyone. What followed was a decade of research at Stanford and Google X in training state-of-the-art models, all in service of that goal. He joined Replit as a pioneer in agentic bui...

Tool, skill, or subagent? Decomposing an agent that outgrew its prompt
When does logic belong in a tool, a skill, or a subagent? You'll learn the decision framework by doing: inherit a 402-line inventory agent, decompose it live on Claude Managed Agents, and run evals after every change to see what flips.

Agents that remember
Every time you close a session, your agent loses everything it learned. In this workshop, you'll wire persistent memory onto a Claude agent and then use Dreaming to batch-consolidate past transcripts into structured recall. By the end of th...
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.
