Anthropic, the artificial intelligence company founded by former OpenAI executives who broke away over concerns about AI safety, is easing a key safeguard that once defined its approach to developing advanced AI systems. In a blog post published Tuesday, the company announced it is replacing its two-year-old “Responsible Scaling Policy” with a more flexible framework. Rather than binding commitments that could halt the development of increasingly powerful AI models, Anthropic said its new policy will consist of public safety goals that can evolve over time. The shift marks a notable change for a company that has long branded itself as...

It might be a beast across the board, but for web developers, the new update is in a league of its own. If you are building for the web, this update isn't just an incremental step—it's a massive leap over 3.0 Pro. While I haven't stress-tested its capabilities in every possible domain, one thing is abundantly clear: in the trenches of web development, it absolutely rocks. The true power of this update isn't just in its first answer—it's in how flawlessly it iterates to get you to your exact end goal. I asked Gemini Pro 3.1 to create a Pacman...

GPT-5.3 Codex is on AIChessArena.com and it wins nearly every game as either Black or White. While other engines tend to draw, Codex actively avoids this. It is highly tactical and has a remarkable grasp of endgame techniques. Like the rest of the engines on aichessarena, the models are given the prompt: “Create a self-contained async chess engine function in JavaScript that is called with a FEN string and a depth search variable. The chess engine then processes the best move with that depth search and returns a promise containing a FEN string representing the new position. Use chess.js for...

Artificial intelligence is moving fast inside enterprises, but security experts warn that defenses aren’t keeping up. As AI agents and large language models are increasingly connected to business systems, they’re quietly expanding the cyberattack surface — and creating new opportunities for attackers, including hostile nation-states. Researchers speaking at a recent Cloud Security Alliance event pointed to the rapid adoption of AI agents that can autonomously interact with data, software tools and APIs. Many of these systems rely on emerging frameworks such as the Model Context Protocol (MCP), which allows models to pull in external data and trigger actions. The problem:...
