The 54b MoE!
### System Info

Hello,

I'm (And I believe many others) are intrigues by the Model of Experts model.

I've looked at the only documentation I could find here: https://github.com/facebookresearch/fairseq/blob/nllb/examples/nllb/modeling/README.md

However the arguments for generation / evaluation are unclear to me :)

I will be starting a data analysis job shortly and I see some possible applications for the 54b model.

Surely there are the other models, but I believe many enthusiasts are looking forward to trying translations with this model. I'm just looking for starting arguments for translating, i.e. eng to de.

I saw the model is coming to huggingface at some point so definitely looking forward to that.

I am also interested in running real person evaluations of 3.3b model, 54b MoE model, Deepl and others to see how far the models have come :)

Thank you so much for your work.

Pinging @ArthurZucker and @younesbelkada who have been working on contributing the Switch Transformer, an MoE, to `transformers`. I agree adding the 54B NLLB model would be quite cool too!<|||||>also personally very interested in support for large MoEs<|||||>This issue has been automatically marked as stale because it has not had recent activity.
