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 20 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 AMD Radeon RX 7900 XT: 8K 16.4 GB · 32K 20.4 GB ✗ · 125K 36 GB ✗. Past 32K it no longer fits 20 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Mistral Small 3.1 24B on 16 GB of system RAM, CPU only: runs, but it is tight.
