Assumes a 4K-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 24 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 XTX: 8K 16.4 GB · 32K 20.4 GB · 125K 36 GB ✗. Past 125K it no longer fits 24 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
