Anthropic is suing the government

the model too dangerous to release

Anthropic announced an unreleased AI model called Claude Mythos Preview that has found thousands of zero-day vulnerabilities in every major operating system and web browser. They say it's too dangerous to release. Meanwhile, Anthropic lost a key court ruling in its ongoing fight with the Pentagon over military AI guardrails. Also this week: Cursor 3.0 brings parallel agents and design mode, Next.js ships a critical security patch (with some irony attached), TanStack introduces code mode for composable tool execution, Payload 3.82 lands with new hooks and drag-and-drop components, plus updates from shadcn, Figma, Claude Code, and Railway.

The "safe" AI company leaked its code

Anthropic accidentally leaked the entire Claude Code source code through an NPM packaging error. Plus Railway's new CDN leaked authenticated user sessions, Google launched a Gemini switching tool and Gemma 3 under Apache 2.0, Cloudflare announced a TypeScript CMS they're calling a WordPress successor (on April 1st), and Payload shipped an LLM evaluation suite. 0:00 Intro 0:26 Anthropic leaked Claude Code's source code 1:45 Railway's CDN leaked authenticated sessions 2:28 Google's Gemini switching tool 3:02 Google Gemma 3 goes Apache 2.0 3:30 Cloudflare's WordPress successor 4:20 Payload 3.81 LLM evaluation suite 4:47 Claude Code updates (7 releases) 5:16 Figma Make Kits & Make Attachments 5:42 Astro 6.1 5:49 TanStack Router signal graph 6:02 Outro Hosted on Acast.

OpenAI's Principles Lasted Exactly 24 Hours

Sam Altman told CNBC he shares Anthropic's safety principles. Less than 24 hours later, OpenAI signed a government contract without those principles and posted about it like a win. Here's why that matters if you build with AI. Hosted on Acast. See acast.com/privacy [https://acast.com/privacy] for more information.
