Can I Run Cogito v1 8B on NVIDIA A100 80GB (PCIe)?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 21 lipca 2026
Yes. Cogito v1 8B needs 6.7 GB at 8K context (4.8 GB weights + 1.9 GB KV cache/overhead) at Q4_K_M and the NVIDIA A100 80GB (PCIe) has 80 GB, leaving about 73.3 GB of headroom, at roughly 149 tok/s (estimated) with room for up to 128K of context.

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 80 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 A100 80GB (PCIe): 8K 6.7 GB · 32K 9.9 GB · 128K 22.8 GB. Every window this model publishes still fits 80 GB.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
