Can I Run Cogito v1 on NVIDIA L40S?
Written by Jakub Rusinowski · Last updated July 21, 2026
Yes, but it's tight — Cogito v1 70B at Q4_K_M needs 45.7 GB at 8K context (42.3 GB weights + 3.4 GB KV cache/overhead), leaving ~2.3 GB of the NVIDIA L40S's 48 GB, at ~18 tok/s (est.), with room for up to 8K context.

Cogito v1 70B on the NVIDIA L40S: VRAM by quantization

| F16 | 143.5 GB | ✗ No | — | — |
| Q8_0 | 77.9 GB | ✗ No | — | — |
| Q6_K | 60.9 GB | ✗ No | — | — |

| Q4_K_M | 45.7 GB | ✓ Yes | 8K | — |

| Q2_K | 26.5 GB | ✓ Yes | 64K | — |
Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 48 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA L40S: 8K 45.7 GB · 32K 53.8 GB ✗ · 128K 86 GB ✗. Past 32K it no longer fits 48 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Cogito v1 on 8 GB of system RAM, CPU only: runs.
