I've currently got a fancy Python script using that model to scan through 15 years worth of transcripts of audio recordings figuring out what the context and subject matter of the recordings are, so that I can sort and search them. Previously they were just a giant pile of audio files.
I used WhisperX to transcribe them. The hardest part was getting pip to install WhisperX correctly, everything else has been just routine Python coding.
There's also Udio.com and Producer.ai out there, and possibly some others - music generation is becoming fairly widespread. I didn't mention any of this in my list of recommendations though because OP specifically asked for LLMs. :)
