Whisper LargeV3 differences between whisper.cpp & python

[magnacartatron]

I'm a bit stuck and maybe someone can help me.

Running whisper large-v3 model via whisper.cpp is significantly more performant than running it through python, VRAM wise and time wise. On a large file python implementation was taking 40GB of VRMA (using Mac Studio)

However I find that running large-v3 through whisper cpp can cause weird anomalies and repetitions that I just don't see when running it through python. Running it through python gives almost perfect accuracy with no weird hallucinations.

What am I missing, how are they so different?

Medium on whisper.cpp seems to be more accurate and hallucinates less than large-v3

I'm working on resolving this issue. It shouldn't affect performance.

Thanks for the hint, BTW. I think it solved my problem :) [switched to medium]

Interestingly, if I enable -tr on medium then it also starts hallucinating. It seems to be a problem with foreign-language-context silences. And for some unknown reason large-v3 translates even if -tr is disabled.

@xaionaro Yes your experience with translation is also happening to me. I think I am going to continue using V2 until V3 problems are solved.
