What separated the models

Qwen3.8-Flash-Next won with the freshest dry wit and a scene that stayed consistent from turn to turn, apart from a small knowledge slip that broke the period setting. MiMo-V2.5 was a strong second but ran over the length limit once. Gemma-4-31B-it followed every rule but was flat. DeepSeek-V4-Flash-0731 slipped in an anachronism and overused its catchphrase, and GLM-4.7 finished last after it stopped using a form of address the user had asked for, one turn after accepting it.
