A practitioner's guide to picking between the three frontier LLM APIs based on task, price, latency, and enterprise terms.
Datadog's bill has a way of tripling the quarter you actually start using it. Here are eight alternatives we've run in production and what each one costs you.
A request leaving a laptop somehow lands on a server 20ms away. Here is what actually decides which point of presence answers.
