Instantcasts -- podcast transcripts and summaries in seconds

I’ve been working on a fun side project around fast Whisper inference that takes the URL to a podcast and, in <10 seconds for an hour-long show, generates a transcript and summary. The actual application is super basic, but it showcases some advanced stuff around optimizing Whisper inference at both a model level and an infra level (e.g. where does the podcast audio file live? it matters!)
