Why we do this

Turning a month of trial-and-error into one call

The model market moves every month. A flagship that led on price in spring can be beaten by an open-weight release by summer, and a tool that's perfect for marketing video is the wrong call for a coding agent. Picking blindly is expensive: you pay for the wrong subscription, rebuild integrations, and lose weeks before you notice. Our whole reason for existing is to collapse that decision from a month of trial-and-error into a single conversation.

We can do that because we're independent — no vendor pays for a ranking here, and we test these models on real production workloads, not demos. So when we recommend something, it's based on how it actually behaves under your constraints: latency, context length, output limits, regional availability, and total cost at your volume. We'll also tell you plainly when the free tier is enough and you don't need to spend anything at all.
