Rethinking LLM Benchmarks: Why Scores Alone Don’t Tell the Full Story

Their behavior shifts depending on prompts, context, updates, and even language. A model that ...

From Generic Evals to Specific Monitors: The Annotation Queue Bridge

How to turn generic evaluation metrics into a useful starting point for AI Reliability. It's common now with all the talk about AI reliability to come to a bit of a conundrum: you know quality matters, but you don't yet know which failures matter most.

I Tracked Every LLM API Call For a Week — 65% Were Unnecessary

I've been using GPT-5 and Claude via API for coding tasks — refactoring, code review, architecture questions, debugging. The bill was creeping past $150/month and I had no idea which calls were actually worth the money. Provider dashboards show you totals. Tokens used, dollars spent, done. But they don't tell you which specific calls were unnecessary. Was that $2.80 request for "where is the auth...

What Is the Difference Between a Routing API and a Route Optimization API?

If you're building a map-based or logistics application, you’ll likely come across two terms that sound very similar: Routing API and Route Optimization API.
