MiniCPM-o 4.5 Finetune

How to fine-tune MiniCPM-o 4.5? I am unable to fine-tune it using LLaMA-Factory following the official tutorial: https://github.com/OpenSQZ/MiniCPM-V-CookBook/blob/main/finetune/finetune_llamafactory_zh.md. Has the fine-tuning code not been released yet, or is there a timeline for when it will be released?
