Assumes a 4K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. 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 19.3 GB · 32K 24.6 GB ✗ · 128K 45.5 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.
