Kimi K3.1 Pro Tech Blog - DECK-Arena: leaderboard

Moonshot AI's in-house DECK-Arena compares presentation decks generated for real-world queries. Models work across python-pptx, pptxjs and Kimi's in-house slide DSL in a harness with integrated search and image generation, and an automated grader calibrated on more than 10,000 human judgments produces Elo scores; higher is better. Unlike the percentage DECK Bench in the Kimi K3 report, this is an Elo arena. Kimi K3.1 Pro launch post benchmark sheet (October 2026); models at max reasoning effort. Moonshot notes that its proprietary-model runs may involve fallback behavior.

Metric: Elo. Source: www.kimi.com.
