Codestral 22B — VRAM Requirements
Written by Jakub Rusinowski · Last updated July 21, 2026
How much GPU VRAM you need to run Codestral Codestral 22B by Mistral AI locally, a 22.2B-parameter model. Figures are quantized weights + KV cache + framework overhead from a memory-bandwidth roofline model.
Codestral 22B needs about 16 GB VRAM at Q4_K_M.
VRAM by Quantization
| Quant | Bits/weight | Weights | Total VRAM |
|---|---|---|---|
| Q2_K | 2.63 | 7.3 GB | 10.0 GB |
| Q3_K_M | 3.41 | 9.5 GB | 12.1 GB |
| Q4_K_M | 4.83 | 13.4 GB | 16.1 GB |
| Q5_K_M | 5.67 | 15.7 GB | 18.4 GB |
| Q6_K | 6.56 | 18.2 GB | 20.9 GB |
| Q8_0 | 8.50 | 23.6 GB | 26.3 GB |
| F16 | 16.00 | 44.4 GB | 47.1 GB |
