Description

As mentioned by @ajjimeno, the encoder is not available to MPS but the decoder is the bottleneck and can be run through a CUDA or MPS backend for GPU acceleration. This MPS backend is supported by the PyTorch framework. Pytorch backend support docs

It would just be to check if MPS is available, detach the encoder and decoder when detecting MPS instead of running model.generate, and map the computational graph of the decoder on the mps device. HugginFace example on MPS backend.

Research direction

Start by reading the PyTorch backend support documentation and the MPS backend example linked in the issue, then locate the Chipper Model inference entry point and its encoder, decoder, and model.generate usage. Done means Apple Silicon can use MPS for the decoder while handling the encoder limitation, with existing inference behavior preserved.
