The only modifications to this version of the model are adding the keys required for the model to be detected as using v-pred and ztsnr Forge and A1111's stable-diffusion-webui dev branch as described in this commit. The original model can be found here: noobaiXL. I have confirmed this model to work as expected on Forge and confirmed outputs to be identical to the original version when used in Swarm with Comfy backend.
