Add IPFS CID

[averyanalex]

I think IPFS is a good alternative to torrent for sharing large files. It has already been successfully used to share/store llama's weights.

Command used to generate CID:

ipfs add grok-1 -r --hash blake3 --chunker size-1048576

I recommend pinning grok-1 weights yourself before merging to check the correctness of my CID.
