GLM 5.3 Flash

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 69. 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.

How much this model is actually called here.

The same model answering different prompt shapes — measured, not benchmarked.

Kyma measures this model twice. Both are real; they answer different questions.

The gap is prompt length, not the model degrading. Use the probe figure to choose between models, the traffic figure to budget for your own.

Pay per token. Cached input bills at this model’s own cached rate, listed below.
