I don’t want to use one of those models. I want to use the one by Kungliga Biblioteket , that will handle both Swedish and English.

The solution is to use the huggingface-cli binary and download the repository from KB:

$ huggingface-cli download KBLab/kb-whisper-small

… then enter the model cache folder in your OpenWebUI installation. I run mine dockerized, and by default it maps the host folder data into /app/backend/data in the container. The Whisper model cache thus ends up at data/cache/whisper/models/ on the host.

Move your downloaded model there, and rename it to match the Systran repo name:

$ mv models--KBLab--kb-whisper-small models--Systran--faster-whisper-small

… and now you can enter “small” (in this example) as the model in the OpenWebUI STT settings and the model you downloaded will be used instead of the one from Systran.

I probably should’ve made a PR on OpenWebUI rather than a blog post, but hey. Maybe it’ll help someone in the meantime.
