Dedicated GPU memory guide
Best local AI models for 6GB VRAM
This guide uses a Windows NVIDIA profile with 6GB dedicated GPU VRAM. It separates full GPU fits, tight fits, and partial offload instead of treating model file size as an official memory requirement.
Dedicated VRAM is not the same as system RAM or Apple Silicon unified memory. For Mac planning, use the Apple Silicon guides so the fit engine uses unified-memory terminology and a Mac-specific conservative budget.
