Written by Jakub Rusinowski · Last updated October 21, 2024
How much GPU VRAM you need to run Granite 3.0 Granite 3.0 8B Instruct by IBM locally, a 8B-parameter model. Figures are quantized weights + KV cache + framework overhead, computed from the model's parameter count and published architecture — not a throughput model. See /en/methodology.
Granite 3.0 8B Instruct needs about 7 GB VRAM at Q4_K_M.
VRAM by Quantization
