title: "Context Window"
type: concept
tags: [AI, 模型, Context]

## Definition
模型能处理的上下文大小,决定了对话长度和信息保留量。
## 典型值
| 模型 | Context Window |
|------|---------------|
| MiniMax-M2.7 | 200K tokens |
| deepseek-reasoner | 16K tokens |
## Compaction机制
OpenClaw的对话压缩机制
- 当对话填满Context Window时将旧消息压缩成摘要
- 摘要抓住要点,但丢失细节(姓名、数字、具体决定)
- safeguard模式预留一半token给compaction
## Memory Flush解决方案
压缩前将重要上下文写入磁盘:
```json
{
"compaction": {
"memoryFlush": {
"enabled": true,
"softThresholdTokens": 4000
}
}
}
```
