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 16 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 NVIDIA GeForce RTX 4070 Ti Super: 8K 9.4 GB · 32K 13.3 GB · 125K 28.5 GB ✗. Past 125K it no longer fits 16 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
