+# YuE2 3B isolated quality test
+
+Prepared, non-starting evaluation of `m-a-p/YuE2-3B` with the standard
+`m-a-p/YuE2-Vae` listening decoder. The source is pinned to the official
+`yue2-v0.1.6` commit `9c6c4b349be978b06a9d0d958471a07a6cdeff4d`.
+
+Preparation on Athena is complete. The model and VAE files were checked
+against their published `weights_manifest.json` SHA-256 values. The Docker
+image is built, but no YuE2 container has been created or started.
+
+## Safety and isolation
+
+- This experiment is not part of the profile controller or dashboard.
+- The Compose service uses the `manual` profile, has no restart policy and
+  cannot start through an ordinary `docker compose up`.
+- Only the RTX 5080 is exposed to the container.
+- Building and downloading do not load the model or use a GPU.
+- Do not start it while another Athena GPU job is active.
+
+## Persistent files

+```
+
+The initial control request is a true empty-lyrics instrumental request. No
+invented `[Instrumental]` lyrics marker is used.
+
+## Manual test (only after GPU availability was checked)
+
+From `/opt/mike-ai/yue2-3b` on Athena:
+
+```sh
+docker compose --profile manual run --rm yue2-test generate \
+  --offline \
+  --device cuda:0 \
+  --budget 16 \
+  --request /workspace/requests/instrumental-synthwave.json \
+  --output /workspace/runs
+```
+
+Start with the official unquantized BF16 path. If and only if this fails from
+VRAM pressure, repeat with `--quantization fp8 --offload-ar`; keep the outputs
+separate because that is a different inference configuration.
+
+YuE2 is newly released and officially specifies a 24-GB BF16 GPU. Readiness of
+this image and the downloaded weights is not evidence that the 16-GB RTX 5080
+run will fit or that its audio quality is acceptable.
