It's absolutely not for these models. There are plenty of consumer GPUs out there with 8 or 12GB VRAM - they are comparatively very fast at inference but just aren't big enough to run lots of the models you want. Also context management is a massive pain.
for inference the compute is the last thing we need more of.
memory bandwidth is the numebr one blocker, after that the inefficiencies that where introduced with MoE models (and all new large models are made that way)
