Replaces llama.cpp Gemma4-12B-QAT (payload + binary retained as rollback). SGLang in a self-contained python3.12 venv with an extracted CUDA 13.0 nvcc toolchain for the sgl-kernel/flashinfer JIT. Shape: fp8 KV, pinned 606,208-token pool / 4 x 151,552 slots, bf16 mamba states pinned at 32 slots (the engine autofills the ssm pool to a fixed ~5.1 GB regardless of dtype), eager prefill (no headroom for graph capture), no spec decode (the checkpoint ships no mtp.* tensors despite mtp_num_hidden_layers=1 — NEXTN drafts with an uninitialised 4.24 GiB ghost at 0% acceptance). Verified: 83.9 tok/s decode, 170k single prompt, 4 concurrent 54k requests, vision (in-checkpoint tower), reasoning_content field.

# Seam: the frank-small SGLang root unit on dankclaw.
|
|
# frank-small is the RTX 3090 endpoint; since 2026-10-01 it serves
|
|
# letechlead/MiMo-V2.6-Distill-Qwen-9B-INT8-W8A16-AutoRound (qwen3_5 hybrid,
|
|
# INT8 W8A16 AutoRound, in-checkpoint vision) via SGLang in a
|
|
# python3.12 venv. This seam pins what the flags alone do not say: boot
|
|
# persistence for a NATIVE runtime (no generated quadlet is involved), the
|
|
# repo-relative paths the unit executes, the separate client port, the
|
|
# no-spec-decode gate (the checkpoint ships NO mtp.* tensors, so a NEXTN
|
|
# draft would be an uninitialised ghost model), the 8-shard payload gate,
|
|
# and the KV budget: fp8 KV at 0.98 utilization whose 4-slot grid must fit
|
|
# the card's 24 GiB.
