I looked at this yesterday, would be great exo can support the deepseek v2, it should be very similar to the llama sharding in the DeepseekV2DecoderLayer. But maybe worth trying model parallelism -> ml-explore/mlx-examples#890

will like to work on this :)

@345ishaan that would be great - go for it

Indeed, MoE is the most suitable application scenario for exo and should be prioritized for implementation.
Really looking forward to it

yeah i was planning to experiment the setup with https://github.com/deepseek-ai/DeepSeek-Coder-V2 . Will be looking into it this weekend.

Is it possible to have the active parameters favor an Nvidia Cuda GPU and let the other nodes store the inactive parameters?

Yes! We can definitely do something like this.
We are moving towards more of a general distributed AI framework that will enable things like this.
