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 192 GB of unified memory. 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 Apple M2 Ultra: 8K 419.5 GB ✗ · 32K 434.8 GB ✗ · 125K 494.1 GB ✗. Past 8K it no longer fits 192 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
