请问这个是哪个模型或者lora May I ask which model or lora this is

Not sure but you could try something like fantasticmix or chilloutmix. They can potentially generate similar style.

Fantasticmix v1.0 might be closest? https://civitai.com/models/22402?modelVersionId=26744

https://civitai.com/models/6424?modelVersionId=11732

you can try checking the png metadata if it has any . if it has metadata then its very easy to find the model/lora
