对文章的疑问

[Cod1ng]

请问，论文里提到For each role, we fine-tune a separate agent model using only the data from the corresponding character experiences, thereby eliminating the issue of character hallucination introduced by the collision of knowledge between the roles.所以是每个角色都微调了一个模型吗？那开源出的 characterGLM 又是怎么训练得到的呢
