For a Keras Core model to be usable with the TF Serving ecosystem, it must be implemented either via Keras APIs (Keras layers and Keras ops) or via TF APIs.

To use pretrained models, you can take a look at KerasCV and KerasNLP, they have all the classics, like BERT, T5, OPT, Whisper, StableDiffusion, EfficientNet, YOLOv8, etc. They're adding new models regularly.
