Frank's order, two messages: "extend the max context of frank-small to 200700 per individual stream without further quantization", then "reduce it to 2 streams for a total of 401400-ish tokens, set ubatch to 1k", then "unquantize the KV if we have extra space". CTX_SIZE 540672 -> 401408 with PARALLEL 3 -> 2 gives n_ctx_slot 200,704: above the 200,700 the harness compacts at, so a full-length request lands in one stream instead of a 400 exceed_context_size_error. The pool must divide evenly across slots and stay 256-aligned for the FA path, which is why it is 401,408 and not 401,400. CACHE_TYPE_V q8_0 -> f16: the freed third slot is exactly what pays for unquantized values (24.5 -> 32 KiB/token), and the budget lands back in the 2-3 GiB band Frank set on 2026-10-02 instead of leaving ~6 GiB of the card idle. The asymmetric-KV contract that created this endpoint is spent with it; both --cache-type flags stay explicit. --batch-size/--ubatch-size are now passed (2048/1024). The endpoint had never passed either, so it ran on engine defaults nobody wrote down. Franksdank-Runbook: serverAppConfigs-docs/LLM/frank-small-llama-mimo-q5km.md

# Serve bartowski/MiMo-V2.6-Distill-Qwen-9B-GGUF (Q5_K_M) as frank-small on
|
|
# Dankclaw's RTX 3090 via llama.cpp (master build, CUDA sm_86).
|
|
#
|
|
# 2026-10-01 night (Frank): swapped from SGLang + INT8-W8A16-AutoRound
|
|
# safetensors to the llama.cpp GGUF path, because llama.cpp is the only
|
|
# runtime on this host that moves K and V independently — the asymmetric
|
|
# f16-K + q8_0-V contract that endpoint was built for. 2026-10-03 (Frank):
|
|
# the pair is now f16/f16 — two wide slots freed the VRAM, so the values are
|
|
# unquantized too. The per-tensor flags stay explicit either way.
|
|
#
|
|
# Architecture: qwen3_5 hybrid — 32 layers, 8 full-attention + 24 Gated
|
|
# DeltaNet, native 262144 window. KV lives only in the 8 attention layers;
|
|
# the DeltaNet state is per-slot fixed size. Vision comes from the repo's
|
|
# separate projector (the Q5_K_M GGUF carries no `v.*` tensors at all), so
|
|
# --mmproj is what gives this endpoint eyes; MMPROJ_FILE="" is the documented
|
|
# text-only opt-out.
|
|
#
|
|
# Sampling: llama.cpp takes it per request (the fleet harness sends its
|
|
# recipe from models.yml); greedy is the harness default.
|
|
#
|
|
# Tunables come from frank-small.env unless FRANK_SMALL_ENV_FILE overrides.
