# frank-default-large ubatch sweep

This benchmark sweeps the active `frank-default-large` model on Dankclaw using
scratch ports and an 8K-context workload. The production service is stopped
before the sweep and restarted by the benchmark's exit handler.

## Sweep

The default points are `256, 512, 768, 1024, 1280, 1536, 2048, 3072, 4096,
5120, 6144`. This implements the requested 256-step range through 1536 and
1024-step range from 2048 through 6144. Each point runs three 256-token decode
requests by default.

Run on Dankclaw from the repository checkout:

```bash
STOPSVC=1 ./scripts/bench-ubatch-rocmi4.sh
```

The script uses the active Q6 AGENT model, standalone MTP draft, tracked Sharp
template, and `--reasoning-format deepseek`. It reports server timing lines and
per-run generation throughput. Run only when the production service can be
interrupted; the GPU is shared with live workloads.

## Results

Record results below after the sweep, including failures or OOM points.
