Altern #18 - Claude Sonnet 5
Claude 5, Europe's AI push, and the rise of Caveman Mode
Another week, another wave of AI updates. This week brought a better default model for millions of Claude users, renewed efforts in Europe to build independent AI infrastructure, and a reminder that even the world’s most powerful AI systems rely on real-world infrastructure. We also take a look at Caveman Mode—a simple prompting technique that’s helping developers get shorter, more efficient AI responses.
Here are the biggest AI stories from the past week.

Caveman Mode: Make Your AI Say More with Less
If you use AI every day, you’ve probably noticed it often spends more time being polite than getting to the point. Caveman Mode is a simple prompting technique that teaches AI to skip the fluff and respond in short, information-packed sentences. It drops unnecessary words, filler, and long explanations while keeping the technical meaning intact, helping reduce output tokens and making responses much faster to read.
It’s especially useful for developers who spend hours coding with AI assistants. Over long sessions, those shorter responses can add up to noticeable token savings without changing the quality of the answers. If you’re curious about how it works, the benchmarks behind it, and how to install it, read the complete article on AI For Developers and check out the open-source Caveman repository.
