Claude Sonnet 4.6

Every number against every text model Kyma prices per token — a stated rule, not a chosen line-up.

Tick above each rail is this model, below it the other 68. Dashed rule is the field median, solid is its best. Better is left; the axis stops at the 90th percentile, so a few models sit past its right edge.
