video model setup pain points on GB200

My first guess would be this: Start by verifying the driver/runtime combo, then test with a smaller prompt, then look at INT4.

What worked for me was pretty simple. If you're on llama.cpp, I'd confirm the version first and then reduce variables until the behavior is obvious. Once you know the plain path works, then add the faster path back in piece by piece.
