# LLM Fleet — Knowledge Base

Documentation for the LLM inference fleet on the two hosts
(2026-09-15): charlie12345/ROCmFPX llama.cpp on Dankserver (frank-medium,
kingjones777 Qwen3.8-27B-ROCmFPX-Q8_0-AGENT on 2x Radeon AI PRO R9700) and
halogen-flash-server 0.5.8 on Dankclaw (frank-large, peonist-ai
Qwen3.8-Flash-Next w4b).

> 2026-08-22: the former `vllmScripts` repository is merged into the
> serverAppConfigs repository. This knowledge base moved from the old repo's
> `serverAppConfigs-docs/` root to `serverAppConfigs-docs/LLM/`. The fleet scripts and units now live in the
> repo's `scripts/` directory.

  FreeToken v0.1.2 frank-small runbook (batsclamp Huihui-Qwen3.6-35B-A3B-
  abliterated-FP8), kept as the retirement record

  quality overlay), rootless Quadlet container on Dankclaw port 7770 —
  deployed flags, memory model, client contract, troubleshooting
- [[dankclaw-iommu-translation-off]] — why Dankclaw boots with
  `amd_iommu=off` since 2026-09-11 (13-16 % prefill, measured upstream),
  what it cost (the NPU endpoint), what was deliberately not copied from
  the reference machine, and how to revert
- [[kingjones-strix-rocmfp4]] — PRIOR frank-large runbook and rollback
  target: kingjones777/Qwen3.8-Flash-Next-ROCmFP4-STRIX-GGUF, 177B params
  (56B MoE + 51.2B PLE), single 113.47 GiB GGUF, on the card's pinned
  kingjones30/ROCmFPX fork (2026-08-30 → 2026-09-11)

  split-mode none (single-GPU), mandatory FA_ALL_QUANTS build flags
- [[kingjones-strix-mtp]] — the former Q6 AGENT runbook (restored 2026-09-01
  after Q8_0 failure, then superseded by the STRIX deployment on 2026-08-27)
