    Generic estimate: weight size is bits-per-weight × parameter count; KV cache uses a reference architecture for the selected size bucket (7B/13B/70B: real published models; 120B: extrapolated, no real model exists at that exact size). Model-specific (HF-synced): weight size is the exact .gguf file size fetched from Hugging Face — no estimation. KV cache is still estimated: this schema doesn't carry layer count, head count, or head dimension, so the calculator parses an approximate parameter count from the model's title (e.g. "8B") and reuses the nearest size bucket's reference architecture for the KV math, same caveats as the generic mode. If no parameter count can be parsed from the title, it falls back to the 7B architecture and says so next to the quantization dropdown. Batch size is fixed at 1 in both modes. Treat all figures here as a starting estimate, not a guarantee. Full formula and known limitations: /methodology.
