Benchmarks tell you who's ahead. Dervity tells you what to use: the best model for your work, and what you give up if you go cheaper or faster.
Paying more doesn't always buy a smarter model.
Each dot is an AI model. Higher is smarter, further right costs more per task. Anything under the green line has a cheaper model that's at least as smart.
