7 LLM Cold Facts Most Developers Get Wrong

Longer context window doesn't mean better comprehension. Flagship models don't always beat smaller ones. The LLM world is packed with counterintuitive facts most developers never question. Reasoning models don't always improve with more thinking time. The same prompt in different languages can score 10+ points apart on benchmarks. Temperature=0 still doesn't guarantee identical outputs. None of this is folklore — there's research data behind each one. Understanding these nuances is what separates sharp model selection from expensive guesswork. XycAi gives you one API to access 200+ models, so you can test and verify all of this with a single integration.
