# ③ 对话上下文扩展到 200k
|
|||
|
|
|
|||
|
|
### 改动点
|
|||
|
|
|
|||
|
|
1. `model-config.json` 新增：`"context_window_target": 200000`
|
|||
|
|
2. `persona-engine.js`：调用模型时设置 max_context 参数为200k
|
|||
|
|
3. `model-router.js`：评测时新增 `context_window` 维度，路由策略优先选200k+模型
|
|||
|
|
4. 如果所有模型 < 200k → 自动启用滑动窗口 + 记忆注入双机制补偿

# ④ 后台自动记忆注入Agent
|
|||
|
|
|
|||
|
|
### 核心问题
|
|||
|
|
|
|||
|
|
对话越长，模型注意力分散，早期关键信息「遗忘」。即使200k窗口也不能保证真正记住。
|
|||
|
|
|
|||
|
|
### 解决方案：三步走
|
|||
|
|
|
|||
|
|
**Step 1 压缩**：把长对话压缩成结构化摘要
|
|||
|
|
|
|||
|
|
**Step 2 注入**：每次调模型前，摘要注入 system prompt
|
|||
|
|
|
|||
|
|
**Step 3 刷新**：每10轮或token>50k时重新压缩
|
|||
|
|
|
|||
|
|
### system prompt 五层结构
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
第1层：人格体身份（固定·来自persona-config.json）
|
|||
|
|
第2层：通感语言风格（固定）
|
|||
|
|
第3层：用户画像（来自profile.json）
|
|||
|
|
第4层：记忆摘要（来自compressed.json·≤8k token）
|
|||
|
|
第5层：最近10轮原始对话（滑动窗口）
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
= 远期记忆不丢 + 近期细节完整
|
|||
|
|
|
|||
|
|
### compressed.json 结构
|
|||
|
|
|
|||
|
|
```json
|
|||
|
|
{

}
|
|||
|
|
}
|
|||

|
```
|

|
|
|

### 配置参数（写入 model-config.json）
|
|||
|
|
|
|||
|
|
```json
|
|||
|
|
{
|
|||
|
|
"memory_injection": {
|
|||
|
|
"enabled": true,
|

|
|
"priority": ["confirmed_decisions", "requirements", "open_questions", "user_preferences", "emotional_signals"]
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
}
|
|||

### 执行清单
|
|||
|
|
|
|||
|
|
- [ ] model-config.json 新增 `memory_injection` + `context_window_target: 200000`
|
|||
|
|
- [ ] 实现 `memory-injector.js`：压缩+注入+刷新三步机制
|
|||
|
|
- [ ] persona-engine.js 改造：调模型前注入五层 system prompt
|
|||
|
|
- [ ] model-router.js 改造：优先选200k+模型
|
|||
|
|
- [ ] 50+轮对话测试：验证模型仍记得早期讨论要点
