+# d1 × d1 21 點對戰實錄
+
+兩個 **LiquidAI d1-3B** 決策模型，各自跑在一個 llama.cpp server 上，在同一張 21 點牌桌上對打。每一次下注、補牌、停牌、加倍，都是模型輸出的機率分佈；這頁把每一步整理成可回放的視覺化紀錄。
+
+- 模型：`LiquidAI/d1-3B-GGUF` (Q8_0)，llama.cpp b11786
+- API：`POST /v1/systemone`（d1 是 decision model，不是文字生成模型）
+- 莊家：規則操作，S17，6 副牌，BJ 3:2
+- 內容：對戰時間軸、決策機率、風險評分、信心度、延遲、資金曲線、動作統計
+- 原始碼：`source/blackjack.py`（對戰 + 記錄）、`source/build_site.py`（靜態網頁編譯）
+- 原始資料：`battle.json`
+
+頁面是靜態的，所有資料都在 `battle.json`；`build_site.py` 可重新編譯整站。

+
+- 模型：`LiquidAI/d1-3B-GGUF` (Q8_0)，llama.cpp b11786
+- API：`POST /v1/systemone`（d1 是 decision model，不是文字生成模型）
+- 莊家：規則操作，S17，6 副牌，BJ 3:2
+- 內容：對戰時間軸、決策機率、風險評分、信心度、延遲、資金曲線、動作統計
+- 原始碼：`source/blackjack.py`（對戰 + 記錄）、`source/build_site.py`（靜態網頁編譯）
+- 原始資料：`battle.json`
+
+頁面是靜態的，所有資料都在 `battle.json`；`build_site.py` 可重新編譯整站。
