How much GPU VRAM you need to run OLMo 2 OLMo 2 7B Instruct by Allen AI locally, a 7B-parameter model. Figures are quantized weights + KV cache + framework overhead from a memory-bandwidth roofline model.
OLMo 2 7B Instruct needs about 5 GB VRAM at Q4_K_M.
| Quant | Bits/weight | Weights | Total VRAM |
|---|---|---|---|
| Q2_K | 2.63 | 2.3 GB | 3.1 GB |
| Q3_K_M | 3.41 | 3.0 GB | 3.8 GB |
| Q4_K_M | 4.83 | 4.2 GB | 5.0 GB |
| Q5_K_M | 5.67 | 5.0 GB | 5.8 GB |
| Q6_K | 6.56 | 5.7 GB | 6.5 GB |
| Q8_0 | 8.50 | 7.4 GB | 8.2 GB |
| F16 | 16.00 | 14.0 GB | 14.8 GB |
