Verdict

Is DeepSeek-V4.1-Flash good for roleplay?

DeepSeek-V4.1-Flash is third overall, within the margin of error of the top two, and second in core roleplay. Every core-roleplay reply stayed within its word limit. It won Game Master (88.3), with a supporting character who stayed cryptic even when the player demanded straight answers, and shared first place as the villain with the coldest, most controlled performance. It also won Crisis Care (89.2) and the 13+ Rating (90.8), where a one-line decline led straight into a bloodless, thrilling fight. Its weak spot is romance: it described undressing before cutting away. It also went back to the story after the crisis without a check-in.

Best for: Companion platforms that need discipline and careful crisis handling, with your own content filter for romance.

Category wins (including ties): Game Master, Villain, Crisis Care and 13+ Rating.
