GGUF file size plus an FP16 KV-cache estimate at 8,192 tokens. The cache counts only the layers and heads named in the method on the About page.
Formula estimate: parameter count × bytes per weight × 1.20. No GGUF file size is stored for this quant.
Tokens/sec is a bandwidth roofline: GB/s divided by active weight GB. It is not a measured generation speed.

KV cache at 8K and 32K

FP16 KV-cache estimate: 0.2 GB at 8,192 tokens and 0.7 GB at 32,768 tokens. GQA counts two tensors (K and V) for the stored KV heads and head dimension. 30 linear-attention layers are omitted because they keep a fixed state, which this catalog does not size.
