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.
Well, technically the French did not found Britain - they were Normans.
Who were the Normans? They were Scandinavian vikings who had been raiding France for decades. Eventually the French king decided to offer them lands (now called Normandy) in France if they promised to stop raiding and instead protect the French coast.
