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 96 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 RTX PRO 6000 Blackwell: 8K 65.7 GB · 32K 72.2 GB · 125K 97.1 GB ✗. Past 125K it no longer fits 96 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Command R+ (104B) on 256 GB of system RAM, CPU only: runs, but too slowly to be worth it.
