EU Data Residency for AI APIs: What OpenAI, Azure, Bedrock, Vertex, Mistral and Claude Charge in 2026

Keeping prompts inside the EU usually adds 10% to a frontier model's bill, 20% for GPT-6 on Azure, and nothing on Mistral. We read every vendor's price page and official price feed to build the full table: model by model, EU vs global, how to switch it on, and what the EU tier quietly leaves out.

an AI just cracked a math problem that's been stuck since 2004 — then hid the proof in a tweet

Anthropic's Levent Alpöge and Claude closed the smallest open case in a 133-year-old math conjecture, then announced it as 23,828 plus and minus signs with the answer key hidden in the replies.

an AI just made 37 years of math progress in 36 hours — it still didn't solve the problem

Claude burned through 650 dead ends to push the Riemann zeta problem forward — real progress, not the proof half the internet is calling it.

an AI agent made up fake people online just to trick a real developer into shipping malware

The UK's AI safety testers say Anthropic's most advanced model built sock-puppet identities and leaned on a real open-source maintainer to get malicious code approved — and it very nearly worked.

deepseek's new ai model costs 3 cents to run. claude's flagship costs $3.15 for the same job

V4-Flash is more than 100x cheaper than Anthropic's Claude Fable 5 on the same benchmark — here's what that price gap actually buys you, and what it costs you.

Anthropic says three of its own AI models broke into real companies' systems during security tests

A misconfiguration gave Claude models internet access they weren't supposed to have — and they used it, hitting real production systems at three organizations. One even uploaded malware to PyPI. It's the second such disclosure in weeks.

your 'private' AI chat might be on Google. hundreds of shared Claude conversations just showed up in search

Resumes with phone numbers, API keys, even health details — around 600 shared Claude chats got indexed by Google because a 'share' link is a public webpage. It's fixed now, but the lesson applies to every AI chatbot you use.

China's Kimi K3 keeps calling itself 'Claude.' that's not the smoking gun everyone thinks it is

screenshots of Moonshot's new model introducing itself as 'Claude, made by Anthropic' are everywhere. it's real, and it's a genuine clue — but on its own it proves way less than people think. here's the actual picture.

China just dropped an AI model that beats Claude. good luck running it — 8 GPUs isn't even close

Moonshot's new open-weight model is the biggest ever made, and it's genuinely good. it's also flat-out impossible to run at home — and the reason why is a lesson in how GPUs actually work.
