Metadata (meta.ipynb)

Metadata introspection for the Voxtral HF plugin used by cjm-ctl to generate the registration manifest.

Import

Functions

def get_plugin_metadata() -> Dict[str, Any]: # Plugin metadata for manifest generation

Plugin implementation for Mistral Voxtral transcription through Hugging Face Transformers

Import

from cjm_transcription_plugin_voxtral_hf.plugin import (
