+## Benchmark an LLM against it
+
+Can a language model *remember a place*? [`llm-benchmark/`](llm-benchmark/) points a
+local Hugging Face `transformers` model at the deployed game and measures how many
+rounds it needs to escape each arc, across all **3 arcs × 3 difficulties × 2
+reading levels**. The model plays exactly like a human (the server owns
+correctness; the answer is never in the payload), so it is a genuine memory test.
+
+```bash
+cd llm-benchmark && pip install -r requirements.txt
+python benchmark.py --base-url http://127.0.0.1:5000 --agent random     # baseline, no model
+python benchmark.py --base-url http://127.0.0.1:5000 \
+    --agent llm --model google/gemma-3n-e4b-it                          # a local model plays
+```
+
+See [`llm-benchmark/README.md`](llm-benchmark/README.md) for the agent protocol,
+the sample prompt, and how to plug in your own model.
