Models run across python-pptx, pptxjs, and Kimi's in-house DSL in a harness with integrated search and image generation; an automated grader calibrated on more than 10,000 human judgments ranks outputs. It is distinct from the earlier DECK-Bench score. BenchLM stores the provider-published internal benchmark value as display-only launch evidence and does not treat it as an independently reproducible score.

DECK-Arena is currently displayed on BenchLM for reference, but it is excluded from the weighted scoring formula.
