The docstring for audio_url is a bit brief. For better clarity and consistency with other parameters like img_url, consider providing a more descriptive explanation of its purpose. Also, this docstring is missing a period at the end. This feedback also applies to the audio_url docstrings on lines 209, 378, and 432.

This logic for handling audio_url is very similar to the logic for other URL-based parameters like img_url, head_frame, etc., leading to code duplication. This can make the code harder to maintain and prone to errors if changes are not applied consistently across all blocks.

To improve maintainability, consider refactoring this repeated logic into a private helper method. For example:

@classmethod
def _maybe_upload_and_set_input(cls, inputs, key, url, model, api_key):
    if not url:
        return False

    is_upload, res_url = check_and_upload_local(model, url, api_key)
    inputs[key] = res_url
    return is_upload

Then you could use it like this:

if cls._maybe_upload_and_set_input(inputs, 'audio_url', audio_url, model, api_key):
    has_upload = True

This would make the _get_input method much cleaner and easier to read. Also, the check if audio_url is not None and audio_url: can be simplified to if audio_url:.


if head_frame is not None and head_frame:
is_upload, res_head_frame = check_and_upload_local(
model, head_frame, api_key)
