Recreate the Flash-Next vs Opus LlamaStash experiment

This is the setup, the run prompt and the scoring I used for Qwen3.8-Flash-Next vs Claude Opus 5.5, made generic so you can run it with your own models, harnesses and hardware. Everything here is public. My 12 PRs are in deepu105/llamastash-b4r2 if you want to compare.

1. What you need

• Repo: llamastash/llamastash, latest main. Write down the SHA you start from and use the same one for every run. The feature isn't in LlamaStash yet, it's the open TODO.md item "Keep a model's prompt cache across an unload". I used 623c28ca11c7f10969208ff4a81392e795f08a31 if you want the exact same starting point.
• A scratch GitHub repo for the PRs, with only main at your start SHA. Turn off its scheduled workflows. All runs open their PRs against it.
• llama-server: a recent [llama.cpp

Here is everything. The scripts and notes are in a private repo, so I'm pasting the relevant parts here.

Start commit

llamastash/llamastash at 623c28ca11c7f10969208ff4a81392e795f08a31 (tip of main on 2026-10-09). main of deepu105/llamastash-b4r2 is pinned to the same commit, so you can fork that too.

Run rules

• Fresh clone per run at that commit, empty target/, one run at a time.
• 3 hour limit. If the agent stopped before it was done, it got one continue. A second stop counts as did not finish. Only one run needed it (Claude Code + Flash-Next xhigh, set 1, PR #7).

Handover: Halogen + gufo behind LlamaStash on Strix Halo

You are setting up a local LLM stack on an AMD Strix Halo machine (Ryzen AI Max+ 395, Radeon 8060S, gfx1151, 128 GB unified memory) running native Linux. When you finish, the user can start any of these from LlamaStash (TUI, CLI, or its OpenAI/Anthropic proxy), each with ready-made presets:

LlamaStash row	Engine	Weights
flash-next-halogen	Halogen (Docker image)	Halogen native v2 .hgn (Qwen3.8-Flash-Next)
Qwen3.8-Flash-Next-UD-Q4_K_XL	gufo (native build)	Unsloth UD-Q4_K_XL GGUF + Unsloth shared MTP head
Qwen3.8-27B-UD-Q6_K	gufo (native build)	Unsloth UD-Q6_K GGUF + z-lab DFlash2 draft
