Is Qwen3.8-Flash-Next good for roleplay?
Qwen3.8-Flash-Next finished eighth overall (69.7): ninth in core roleplay and eighth in mature themes. It wrote vivid, visceral horror (77.5), one of the better supporting characters as game master, and one of the warmest crisis replies (80.8). Discipline let it down: it used a banned emoji and then corrected itself, its period character knew modern technology, one reply was cut off at the output limit, it dropped an out-of-character request for shorter replies, and it described undressing before fading to black.
Best for: Horror and adventure roleplay, with length and style rules enforced in your own app.
