Cogito v1 3B — VRAM Requirements
Written by Jakub Rusinowski · Last updated March 20, 2026
How much GPU VRAM you need to run Cogito v1 Cogito v1 3B by Deep Cogito locally, a 3B-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.
Cogito v1 3B needs about 4 GB VRAM at Q4_K_M.
VRAM by Quantization
| Quant | Bits/weight | Weights | Total VRAM |
|---|---|---|---|
| Q2_K | 2.63 | 1.0 GB | 2.7 GB |
| Q3_K_M | 3.41 | 1.3 GB | 3.0 GB |
| Q4_K_M | 4.83 | 1.8 GB | 3.6 GB |
| Q5_K_M | 5.67 | 2.1 GB | 3.9 GB |
| Q6_K | 6.56 | 2.5 GB | 4.2 GB |
| Q8_0 | 8.50 | 3.2 GB | 4.9 GB |
| F16 | 16.00 | 6.0 GB | 7.7 GB |
