Okay I have looked at the existing mistral model and I wanted to used it as a template but after looking at the Devstral-Small (https://huggingface.co/mistralai/Devstral-Small-2507/tree/main) I couldn't find where are the changes @sachinprasadhs and I got the impression that devstral-small is just fine tuned model of the mistral model. Please forgive me if I missed something quite obvious.

Yes, Devstral small 1.1 is a finetuned version from Mistral small, you should be able to use the same model architecture, but may need the verification and changes if required in the conversion script for Devstral https://github.com/keras-team/keras-hub/blob/master/keras_hub/src/utils/transformers/convert_mistral.py
