Not sure if this will help but I've set up Handy [1] with Parakeet V2 for STT and gpt-oss-120b on Cerebras [2] for post-processing and I'm happy with the performance of this setup!
But the advantage here is — what? That I don't have to pay for it? I'm glad it works for you, but I'm in a (solo) business setup where I'd much rather pay a (very reasonable) amount of money for a tool that gets things right and smooths out the edges.
