Assumes an 8K-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 128 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 Ryzen AI Max+ 395: 8K 76.1 GB · 32K 84.7 GB · 128K 118.9 GB. Every window this model publishes still fits 128 GB.
