So sure, maybe make the ML model a separate service, but you don't really have the same driver for other services; state-less server processes tend to need the same type of resources only in different amounts, and you don't really gain anything by splitting your work load based on the words used in your domain description.

Real-world monoliths often do have some supporting services or partner services that they interact with. That doesn't mean you need a "micro-service architecture" in order to scale your workload.
