Is MiMo-V2.5 good for roleplay?
MiMo-V2.5 finished second in both rounds and never scored below 60 in any category. It won Robustness by turning one-word user replies into real plot and deflecting an off-topic request without breaking character, won Crime Noir with the most complete, patient menace, and tied for first as the Villain. In core roleplay it never wrote the player's actions. Its weak spots are vaguer horror, a bulleted list that broke a companion's word limit, and refusals that sound like an assistant rather than the character, including one that stopped a 13+ adventure outright.
Best for: General-purpose companion and adventure apps that need steady quality in every kind of scene.
Category wins (including ties): Villain, Robustness and Crime Noir.
Strengths
- Carries the story when the user goes quiet
- Handles off-topic derails without leaving the story
- Strong crisis response with concrete resources
- Cleanest on player agency as game master
Weaknesses
- Horror stays vague rather than specific
- Assistant-voice refusals that halt the scene
- Occasional list formatting that breaks word limits
- Forgot an out-of-character request for shorter replies
