# frank-dragoon — unsloth llama.cpp Qwen3.8-Flash-Next UD-IQ4_XS (RETIRED)

> **RETIRED 2026-09-21 (same-day swap).** This was the ACTIVE frank-dragoon
> runbook on 2026-09-21 before it was replaced by
> [[frank-dragoon-unsloth-qwen38-27b-q8xl]] (27B dense UD-Q8_K_XL) later the
> same day. The payload and runtime remain on disk as the rollback target.

## What it served

- **Runtime:** unsloth llama.cpp prebuilt `b11030-mix-5ff778e` (ROCm
  gfx1151), root systemd unit, port 7770.
- **Model:** `unsloth/Qwen3.8-Flash-Next-GGUF:UD-IQ4_XS` (a 125B MoE / 6B
  active), 87.3 GiB shipped as three split parts. The split parts ARE the
  payload — concatenating them trips `invalid split file name` (part 1's
  header advertises `file_count=3`).
- **Shape:** one 200,000-token conversation (single stream), MTP depth 2 via
  the explicit `-md` shared-Q8_0 head. Draft acceptance verified live
  0.83–0.92.
- **Memory:** the 114 GiB GTT aperture on the Strix Halo iGPU.

## Rollback

Payload and runtime intact on disk. See [[frank-dragoon-unsloth-qwen38-27b-q8xl]]
for the current ACTIVE runbook and [[frank-dragoon-ciru-orca]] for the
predecessor.
