    Typically you need about 1GB graphics RAM for each billion parameters (i.e. one byte per parameter). This is a 405B parameter model. Ouch.

    Edit: you can try quantizing it. This reduces the amount of memory required per parameter to 4 bits, 2 bits or even 1 bit. As you reduce the size, the performance of the model can suffer. So in the extreme case you might be able to run this in under 64GB of graphics RAM.

      At work we habe a small cluster totalling around 4TB of RAM

      It has 4 cooling units, a m3 of PSUs and it must take something like 30 m2 of space

      According to huggingface, you can run a 34B model using 22.4GBs of RAM max. That’s a RTX 3090 Ti.

      Hmm, I probably have that much distributed across my network… maybe I should look into some way of distributing it across multiple gpu.

      Frak, just counted and I only have 270gb installed. Approx 40gb more if I install some of the deprecated cards in any spare pcie slots i can find.
