| We provide the ability to create custom node initialization behaviors with the API defined by [`CallbackBase`](https://github.com/ray-project/ray/blob/master/python/ray/llm/_internal/common/callbacks/base.py). Callback functions defined in the class are invoked at certain parts of the initialization process. An example is the above mentioned [`CloudDownloader`](https://github.com/ray-project/ray/blob/master/python/ray/llm/_internal/common/callbacks/cloud_downloader.py) which overrides the `on_before_download_model_files_distributed` function to distribute download tasks across nodes. To enable your custom callback, specify the classname inside `LLMConfig`. | ||

There was a problem hiding this comment.
nit: for changes like these i prefer adding them to a doc_code directory with e2e working example. Advantage is that if the API changes, the example would fail the docs test.
