Measured after the first 3-slot deploy: 3 x 196,608 booted (n_slots=3, n_ctx_slot=196608, multimodal loaded) but used 22,972/24,576 MiB - 1,153 MiB free, outside the 2-3 GiB band. The two measurements now recorded in frank-small.env price the vision tower at ~1.4 GiB (non-KV 7,390 -> 8,859 MiB), so the pool drops 49,152 tokens (16,384/slot, 1,176 MiB) to land ~2.7 GiB free. The bats budget gate is recalibrated to the measured 9 GiB non-KV cost, which now rejects the 3 x 196,608 shape instead of blessing it.

# 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 can serve the MiMo qwen35 hybrid with
|
|
# ASYMMETRIC KV: --cache-type-k f16 (unquantized keys) + --cache-type-v
|
|
# q8_0 (quantized values), which is Frank's explicit KV contract for this
|
|
# endpoint. SGLang's --kv-cache-dtype only moves K and V together.
|
|
#
|
|
# 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.
