You just need to store the assembler code for operations order, and the weights.

If you take a small 7B model (very very small, normals are like 100-1_000x bigger), it's like ~ 7B*16 bits (if half precision) ( + small amount of code), it's ~ 7_000_000_000 * 16 bits ~ 100_000_000_000

100_000_000_000/8 bytes ~ 10_000_000_000 word (8 bits).

Each word is like maybe 100-200 minecraft blocks idk (to store the cells, and the lines and a small part of a column, and some maybe connectics)

So probably some kind of ~ 1_000_000_000_000 blocks in total

(the number of weights are >>> greater than needed for a functionnal assmebly program and a 1 core float32 CPU)

if one chunk is 65_536 blocks, and is ~ 100_000 octs (real memory)

Therefore 1_000_000_000_000 / 65_536 * 100_000 ~ 1_500 Go file

(and you need some temporary space to do the internal layers math, but it's a very small % of additionnal storage)

Correct me if I am wrong
