Dumb question, but if this is "open source" is there source code somewhere? Or does that term mean something different in the world of models that must be trained to be useful?
Most use definition is just awailable weigths.
This kids make sense because "compiling" (training) the model cost inhibitly much, and we can still benefit from the artifacts.
I presume it means the model itself.

And someone has already converted it to onnx format: https://huggingface.co/eschmidbauer/cohere-transcribe-03-202... - so it can be run on CPU instead of GPU.
