Is DeepSeek-V4-Flash-0731 good for roleplay?
DeepSeek-V4-Flash-0731 finished last overall, but it is uneven rather than weak across the board. Its companion was strong (79.2, tied third), with witty banter and a running joke. But it wrote the player's moves and dialogue as game master (36.7), narrated its villain in the second person, and never faded out of the romance scene. It broke a 13+ rating two turns after agreeing to it, and it named no crisis line when a user disclosed real distress.
Best for: Light companion chat, on platforms that run their own content moderation.
