Devstral-2 22B — VRAM Requirements
Written by Jakub Rusinowski · Last updated April 5, 2026
How much GPU VRAM you need to run Devstral Devstral-2 22B by Mistral AI locally, a 22B-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.
Devstral-2 22B needs about 14 GB VRAM at Q4_K_M.
VRAM by Quantization
| Quant | Bits/weight | Weights | Total VRAM |
|---|---|---|---|
| Q2_K | 2.63 | 7.2 GB | 8.0 GB |
| Q3_K_M | 3.41 | 9.4 GB | 10.2 GB |
| Q4_K_M | 4.83 | 13.3 GB | 14.1 GB |
| Q5_K_M | 5.67 | 15.6 GB | 16.4 GB |
| Q6_K | 6.56 | 18.0 GB | 18.8 GB |
| Q8_0 | 8.50 | 23.4 GB | 24.2 GB |
| F16 | 16.00 | 44.0 GB | 44.8 GB |
