How to Test an LLM: Benchmarks, Arenas, and Real Evals
Every couple of weeks some AI lab drops a new model and immediately claims it’s the smartest thing on the planet. Then another lab does the same thing a week later. If you’ve ever tried to figure out which one is actually better, you’ve probably stared at a wall of charts with names like MMLU, GPQA, and SWE-bench and felt your eyes glaze over. I went down this rabbit hole recently, and here’s the short version: there’s no single scoreboard. There are at least four completely different ways people measure “better,” and once you know what each one is actually doing, the whole AI leaderboard circus starts to make a lot more sense.

Claude Subscription vs Anthropic API Key: Key Differences
Millions of people use Claude every day — but there’s a crucial distinction that trips up beginners and developers alike: a Claude.ai subscription and an Anthropic API key are two entirely separate products with different pricing, access methods, and intended audiences. Understanding which one you actually need can save you money and prevent frustrating “why doesn’t this work?” moments. What Is the Claude.ai Subscription? A Claude.ai subscription gives you access to Anthropic’s conversational AI interface through the web app, desktop client, and mobile apps [1].
