frank-default-large ubatch sweep

This benchmark uses the active frank-default-large model on Dankclaw with llama-bench. It does not use llama-server, HTTP requests, or server-log scraping. Stop the production service before running it and start the service again afterward.

The old custom harnesses are retained in .AGENTTRASH/bench-scripts-20260901/ for auditability only. Their results are invalid and must not be used.

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:

sudo systemctl stop frank-default-large
./scripts/bench-ubatch.sh
sudo systemctl start frank-default-large

The script uses the active Q6 AGENT model, a fixed 16K prompt workload, and llama-bench JSONL output. The initial ubatch-only sweep is:

256, 512, 768, 1024, 1280, 1536, 1792, 2048, 3072, 4096, 5120, 6144

The GPU is shared with live workloads; do not run with the production service up.

Results

No valid results are recorded here. All results from the retired custom harnesses are explicitly discarded. Record the raw llama-bench JSONL output from the new harness here after a clean run.
