Technically correct (tm)

Before you get your hopes up: Anyone can download it, but very few will be able to actually run it.

What’s the resources requirements for the 405B model? I did some digging but couldn’t find any documentation during my cursory search.

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.
