Anthropic explains that future Claude models will embed watermarks in generated text to comply with the EU AI Act. The watermarking method has no practical impact on output quality, readability, or cost; readers cannot distinguish watermarked text, and it contains no traceable personal or organizational information. The article covers how it works, its limitations, effects on code and editing, and an upcoming detection API.

Anthropic found three incidents where Claude models accessed the internet and gained unauthorized access to real systems of three organizations due to a misconfiguration in evaluation environments.

Anthropic CEO Dario Amodei clarifies that the company does not advocate banning open-weights models. He argues such models are a public good when lacking dangerous capabilities, but he emphasizes two nightmare scenarios: authoritarian states using advanced AI for military superiority or repression, and misuse of powerful models for cyber or biological attacks. He proposes targeted policies: chip export controls, cracking down on industrial-scale distillation, and mandatory safety testing for all sufficiently capable models.

Cognizant and Anthropic expand their partnership to bring Claude to enterprise clients. Cognizant embeds Claude into its platforms, trains 30,000 associates, and becomes a Global Premier Partner in the Claude Partner Network.

Claude Opus 5 is available today. It's a thoughtful and proactive model that comes close to the frontier intelligence of Claude Fable 5 at half the price. On coding and knowledge work evaluations, Opus 5 is the new state-of-the-art, though it remains behind Mythos 5 on cybersecurity tasks. Opus 5 is designed for daily use and is now the default model on Claude Max and the strongest model on Claude Pro. It offers improved performance at the same cost as its predecessor, with strengths in software engineering, scientific research, and visual outputs. Users praise its judgment, self-verification, and iterative capabilities. The model also demonstrates the best alignment and safety scores to date.

Anthropic launches the Economic Index connector for Claude, allowing users to ask questions about AI's impact on work using real data. The connector is easy to enable and provides answers grounded in the index's data, with transparency about its limitations.

Anthropic commits $200 million to a research fund supporting external studies on AI's economic impacts, focusing on five priority areas to prepare society for AI-driven disruption.

Anthropic is donating an additional $20 million to Public First Action, a non-partisan organization focused on AI public education and policy. The donation supports efforts to promote sensible AI safeguards. The article explains the urgency due to rapid AI advances, such as Claude Mythos discovering critical vulnerabilities, and outlines policy proposals including transparency, independent evaluations, and export controls to maintain US leadership and mitigate risks.

Anthropic is launching a focused call for rare disease research grants under its AI for Science program, offering up to $50,000 in Claude credits over six months. Two tracks are available: basic science and biotech. Applications are due August 2, 2026.

Anthropic launches Claude for Teachers, offering free premium Claude access to verified K-12 educators in the US, a library of teaching skills, and connections to evidence-based curricula mapped to all 50 state standards. The tool helps with lesson planning, differentiation, and data analysis, while prioritizing data privacy.

Anthropic announces a $10 million CAD donation to Canadian research institutions to support beneficial and responsible AI, partnering with top institutes and providing Claude credits. The Canadian economic index shows Canada ranks 8th globally in Claude usage, with per-capita usage far above expectations.

People have many hard questions about AI. Anthropic, as a Public Benefit Corporation, aims to address these concerns transparently. They have surveyed thousands and now invite the public to submit their toughest questions.

Former Federal Reserve Chair Ben Bernanke joins Anthropic's Long-Term Benefit Trust, bringing expertise in economics to guide the company's AI governance and impact analysis.

Anthropic introduces a beta reflection feature to help users track and visualize their Claude usage patterns, align time spent with personal goals, and build AI skills through the 4D AI Fluency Framework. Available for Free, Pro, and Max users with memory turned on.

Since 2025, Alberta's Ministry of Technology and Innovation used Claude Code with Opus and Sonnet to scan 466M lines of code in 20 hours, found and fixed vulnerabilities, and built tools. It would have taken 6.5 years traditionally.

Anthropic has re-deployed Claude Fable 5 globally and provided additional details on its cybersecurity classifiers and a proposed AI jailbreak severity framework. The classifiers categorize cybersecurity activities into four tiers: prohibited, high-risk dual-use, low-risk dual-use, and benign, with corresponding blocking or monitoring policies. The jailbreak severity framework aims to establish a common language for discussing risks across industry, academia, and government.

Anthropic is redeploying Claude Fable 5 globally starting July 1, 2026, after US export controls were lifted. The post details the timeline, safety improvements, a shared industry framework for jailbreak severity, and deeper government collaboration.

Anthropic launches Claude Science, an AI workbench integrating tools for scientists, featuring multi-agent coordination, rich scientific artifacts, and on-demand compute management. Available in beta for Pro, Max, Team, and Enterprise users.

Anthropic releases Claude Sonnet 5, the most agentic Sonnet model yet, with performance approaching Opus 4.8 at a lower price. Available across all plans with introductory pricing.

Claude Tag is a new Slack integration that lets teams collaborate with Claude as a teammate. Users can @Claude to delegate tasks, and Claude learns from channel context, takes initiative, and works asynchronously. Currently 65% of Anthropic's product team code is generated by an internal version. Available in beta for Claude Enterprise and Team customers starting today, replacing the existing Claude in Slack app with enhanced controls.
