+# 0973 将默认模型从 kimi 改成 deepseek-flash
+
+## What
+
+将 LLM 插件模型清单的默认模型从 `kimi-k3` 改为 `deepseek-v4-flash`。
+
+## Why
+
+产品要求默认模型切换为 deepseek-flash（清单中对应条目 `deepseek-v4-flash`）。
+
+## How
+
+`qt_chat_model.cpp` 的 `resolve_default_key` 优先读取清单顶层 `default` 字段，
+因此只需修改 `TeXmacs/plugins/llm/data/liii_llm_menu.json` 的 `"default"` 值为
+`"deepseek-v4-flash"`。`qt_chat_model.cpp` 中的兜底清单（Kimi-VLM 单条目）仅在
+清单文件缺失/解析失败时启用，属于既有兜底行为，不在本任务范围内。
+
+## 涉及文件
+
+- `TeXmacs/plugins/llm/data/liii_llm_menu.json`：`"default": "kimi-k3"` → `"deepseek-v4-flash"`
+- `devel/0973.md`：任务文档
+
+## 测试
+
+- `xmake b qt_chat_model_test && xmake r qt_chat_model_test`：验证默认 key 解析
+  逻辑（显式 default 优先）不受影响。
