This directory prepares an isolated comparison of two Qwen3.8-27B IQ4_XS artifacts without adding router profiles or changing the running Athena stack.

Candidates

ID	Artifact	Purpose	Pinned revision	Size
`qwopus`	`Jackrong/Qwopus3.8-27B-Flash-GGUF` / `Qwopus3.8-27B-Flash-MTP-IQ4_XS.gguf`	Efficiency fine-tune	`e146d61e88782677805b3b68ad3adf8674dde80d`	15,420,445,792 B
`bartowski`	`bartowski/Qwen3.8-27B-GGUF` / `Qwen3.8-27B-IQ4_XS.gguf`	Standard Qwen, alternative IQ4_XS quant	`f0eec4a4bb4975114a030d048952d83c0a53c034`	15,567,824,480 B

The production reference remains jpetrina/Qwen3.8-27B-IQ4_XS-pure-GGUF. The candidates intentionally use the same IQ4_XS quantization class so that the first comparison does not mix a fine-tune difference with a quantization-class difference.

Safety boundary

Nothing in this directory is called by installation, Compose or the router.
No production profile is added.
Downloads happen only after explicitly running download-candidate.sh.
run-case.sh refuses to start while a production mike-ai-llama-* model is running. It never stops production itself.
The test server binds to 127.0.0.1:5005 and is not exposed to the LAN.
Cleanup is a dry run unless an explicit deletion flag is supplied. It only addresses the exact test container, result directory and two pinned files.

Later test sequence

Run these commands on Athena only after the active coding task has finished and the GPUs have deliberately been released:

cd /opt/mike-ai/stack/experiments/qwen38-20260907-ab
./inventory.sh
./download-candidate.sh qwopus
./download-candidate.sh bartowski

./run-case.sh qwopus 160000 85,15
./wait-ready.sh
./run-benchmark.sh qwopus-160k
./stop-case.sh

./run-case.sh bartowski 160000 85,15
./wait-ready.sh
./run-benchmark.sh bartowski-160k
./stop-case.sh

Only after both candidates pass the 160K quality and tool-call tests should 192K and 262144 be attempted. Promotion into the router is a separate decision and is deliberately not implemented here.

Cleanup

Preview everything owned by this experiment:

./cleanup.sh

Remove only the test container and benchmark results:

./cleanup.sh --results

Remove only the two downloaded candidate files and their now-empty directory:

./cleanup.sh --models

Remove both:

./cleanup.sh --all

The script never touches the production Pure, Mix, Beta 1 or uncensored model directories.
