# frank-small — llama.cpp (master, CUDA sm_86) serving # bartowski/MiMo-V2.6-Distill-Qwen-9B-GGUF:Q5_K_M on the RTX 3090, :7771. # # 2026-10-01 night (Frank): one quant step down from the Q6_K file this # endpoint ran for a few hours, on the same runtime and the same shape — the # llama.cpp GGUF path is kept for the ASYMMETRIC KV contract (K unquantized # f16, V q8_0) that no other runtime on this host exposes per-tensor, and the # freed 0.86 GiB of weights is what keeps the two full windows bootable with # margin for CUDA graphs. # # KV arithmetic: attention KV exists only in the 8 full-attention layers # (4 KV heads x 256 head_dim). K f16 = 16 KiB/token; V q8_0 = 8.5 KiB/token # (34 B per 32-element block) => 24.5 KiB/token. Two full native windows # (2 x 262,144 = 524,288 tokens) cost 12.5 GiB; weights 6.40 + KV 12.5 + the # fixed Gated DeltaNet state (~25 MiB/slot) + compute buffers and CUDA graphs # ~1.5-2 => ~20.5 GiB against the card's 24 GiB. Q6_K measured 20.9/24.6 here, # which is the same arithmetic with 7.26 GiB of weights. # # Why V is not f16: full-precision V costs 16 KiB/token instead of 8.5, i.e. # +3.96 GiB on a 524,288-token pool — 24.5 GiB total, past the card. If the # graph capture OOMs, lower CTX_SIZE (262144 = two 131,072 windows) rather # than quantizing K.
