How this ranking works

Benchmark is an aggregate 0–100 quality score. Blended price assumes a 3:1 input-to-output token mix. Trend compares the latest blended price with the oldest in our 6-month history.

This page sorts by blended price /1m. Use the panel on the right to switch ranking or category — every combination has its own page.
