Verdict

Is Kimi-K3 good for roleplay?

Kimi-K3 leads the benchmark, first in both core roleplay and mature themes, although its lead over GLM-5.3 and DeepSeek-V4.1-Flash is within the margin of error. It played the best companion (90.8) and the best romance lead (90.0), slowing a scene down in character instead of needing a fade to black, and it shared first place as the villain and in graphic horror. It was one of only three models still following an out-of-character request for shorter replies a turn later, and it turned an off-topic request into a plot clue without leaving the story. Its weak spots: as game master it scripted extra moves for the player's character, and some replies ran over their word limits.

Best for: Companion, romance and general roleplay apps that want the strongest all-rounder.

Category wins (including ties): Companion, Villain, Graphic Horror and Romance Limits.
