It's also annoying since there appears to be a hard limit of 25 MiB to the request size, requiring you to split up larger files and manage the "prompt" to subsequent calls. Well, somehow, near as I can tell, how you're expected to use that value isn't documented.
I doubt it will matter if you're breaking up mid sentence if you pass in the previous as a prompt and split words. This is how Whisper does it internally.
I suggest you give revoldiv.com a try, We use whisper and other models together. You can upload very large files and get an hour long file transcription in less than 30 seconds. We use intelligent chunking so that the model doesn't lose context. We are looking to increase the limit even more in the coming weeks. It's also free to transcribe any video/audio with word level timestamps.
If you're interested in an offline / local solution: I made a Mac App that uses Whisper.cpp and Voice Activity Detection to skip silence and reduce Whisper hallucinations: https://apps.apple.com/app/wisprnote/id1671480366
If it really works for you, I can add command line params to an upate, so you can use it as a "local API" for free.
