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 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 5.9 GB · 32K 7.3 GB · 128K 12.9 GB. Every window this model publishes still fits 16 GB.
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
