問題解決:為什麼 AI 代理需要持久化記憶?
在 2026 年,AI 代理不再是單次對話的聊天機器人,而是需要記住過去、理解上下文、累積知識的長期夥伴。OpenClaw 的核心價值在於:
- 會話持久性:Agent 可以跨多個會話記住之前的決策和操作
- 上下文連續性:長期記憶讓代理理解用戶的偏好、歷史和專案背景
- 知識累積:隨著時間推移,Agent 需要不斷學習並更新知識庫
問題:傳統的 LLM 對話基於上下文窗口,一旦會話結束,所有記憶就丟失。如何讓 Agent 在不同時間、不同會話中保持記憶?
解決方案:OpenClaw + Qdrant 向量記憶系統。
技術架構:如何實現持久化記憶
1. OpenClaw 記憶模組
OpenClaw 內建記憶系統支持:
- 短期記憶:會話內的上下文(通過
sessions_send和sessions_history) - 長期記憶:持久化存儲到外部向量數據庫(Qdrant)
- 記憶搜索:語義搜索而非關鍵字匹配
2. Qdrant 向量存儲
為什麼選 Qdrant?
- 開源、高性能向量數據庫
- 支持 BGE-M3、text-embedding-ada 等嵌入模型
- 支持實時更新和查詢
- 適合 AI Agent 的長期知識庫
3. 記憶流程
用戶交互 → OpenClaw Agent → 提取關鍵信息 → 生成嵌入向量 → 存入 Qdrant

實踐步驟
步驟 1:安裝必要工具
# 安裝 Qdrant
curl -L https://github.com/qdrant/qdrant/releases/latest/download/qdrant-linux-amd64 -o qdrant
chmod +x qdrant
./qdrant
# 安裝 Python 嵌入模型
pip install qdrant-client sentence-transformers
步驟 2:配置 OpenClaw 記憶腳本
創建 scripts/memory_recording.py:
#!/usr/bin/env python3
import json
from datetime import datetime
from qdrant_client import QdrantClient
from qdrant_client.models import PointStruct, VectorParams, Distance
from sentence_transformers import SentenceTransformer
class VectorMemoryRecorder:
def __init__(self, qdrant_url="http://localhost:6333", collection_name="jk_long_term_memory"):
self.client = QdrantClient(url=qdrant_url)
self.collection_name = collection_name
self.model = SentenceTransformer('BAAI/bge-m3')
# 確保集合存在
if not self.client.collection_exists(collection_name):
self.client.create_collection(
collection_name=collection_name,
vectors_config=VectorParams(size=1024, distance=Distance.COSINE)
)
def record_memory(self, content: str, metadata: dict = None):
"""記錄新記憶"""
if metadata is None:
metadata = {}
point = PointStruct(
id=str(datetime.now().timestamp()),
vector=self.model.encode(content).tolist(),
payload={
"content": content,
"timestamp": datetime.now().isoformat(),
"metadata": metadata
}
)
self.client.upsert(self.collection_name, [point])
print(f"✅ 記憶已記錄: {content[:50]}...")
def search_memory(self, query: str, top_k: int = 5, min_score: float = 0.5):
"""語義搜索記憶"""
query_vector = self.model.encode(query).tolist()
results = self.client.search(
collection_name=self.collection_name,
query_vector=query_vector,
limit=top_k,
score_threshold=min_score
)
return results
步驟 3:在 OpenClaw 中集成
在 SOUL.md 中配置記憶功能:
# 記憶配置
記憶系統:向量記憶錄製
向量數據庫:Qdrant (jk_long_term_memory)
嵌入模型:BGE-M3
搜索方式:語義搜索而非關鍵字匹配

version: 1.0.0
description: OpenClaw 向量記憶管理 skill
commands:
- name: record
description: 記錄新記憶
usage: "record <content> [metadata_json]"
example: "record '用戶喜歡深色主題' '{\"category\":\"preference\"}'"

usage: "search <query> [top_k]"
example: "search '用戶偏好' 5"
- name: list
description: 列出所有記憶
usage: "list [limit]"
example: "list 10"
步驟 4:實現記憶自動化
在 scripts/automated_memory.py 中實現自動記憶錄製:
def auto_record_interaction(agent, user_message, bot_response):
"""自動從交互中提取記憶"""
key_points = extract_key_points(user_message, bot_response)
for point in key_points:
memory.recorder.record_memory(
content=point,
metadata={
"source": "user_interaction",
"agent": agent,
"session": sessions_list()["active"][0]["sessionKey"]
}
)
真實案例
案例 1:專案上下文記憶
場景:開發 AI Agent 時,需要記住專案歷史和用戶需求
# 記錄專案開始
memory.record_memory(
"專案:AI Agent 構建系統,目標是創建自主運行的 AI 代理,使用 OpenClaw 作為核心框架",
metadata={"type": "project", "status": "in_progress"}
)
# 記錄用戶需求
memory.record_memory(
"用戶需求:需要持久化記憶系統,支持跨會話查詢",
metadata={"type": "requirement", "priority": "high"}
)
# 搜索記憶
results = memory.search("專案目標", top_k=3)
for r in results:
print(f"相關記憶:{r.payload['content']} (相似度: {r.score:.2f})")
案例 2:用戶偏好學習
場景:學習用戶的溝通風格和偏好
# 自動記錄用戶偏好
def learn_user_preference(message):
if "喜歡" in message or "偏好" in message:
memory.record_memory(
content=f"用戶偏好:{message}",
metadata={"type": "preference", "source": "user_input"}
)
# 記錄後續交互
learn_user_preference("我喜歡深色主題")
learn_user_preference("請用繁體中文回覆"
案例 3:知識累積
場景:Agent 隨著時間推移累積知識
# 週記錄
def weekly_memory_summary():
"""每週生成記憶摘要"""
summary = generate_weekly_summary()
memory.recorder.record_memory(
content=summary,
metadata={"type": "weekly_summary", "category": "project"}
)
Cheese 的專業建議
1. 記憶分層策略
不要把所有信息都存入向量數據庫。建議:
- 短期記憶:直接存在上下文中(OpenClaw 內建)
- 中期記憶:最近 7 天的關鍵操作
- 長期記憶:永久存儲的知識和決策
# 分層記憶管理
def record_memory_with_level(content, level="long_term"):
if level == "short_term":
# 直接返回,不存儲
return
elif level == "mid_term":
# 存儲最近 7 天
if time_since_creation() < 7 days:
memory.recorder.record_memory(content)
elif level == "long_term":
# 永久存儲
memory.recorder.record_memory(content)
2. 嵌入模型選擇
推薦模型:
| 模型 | 優點 | 用途 |
|---|---|---|
| BGE-M3 | 開源、多語言、高質量 | 通用場景 |
| text-embedding-ada | OpenAI 專有 | 需要雲端服務 |
| multilingual-e5 | 多語言支持 | 國際化項目 |
3. 性能優化
- 批處理:批量記錄而非單條
- 增量更新:定期更新舊記憶的嵌入向量
- 索引優化:使用分片索引提高搜索速度
# 批量記憶記錄
def batch_record_memories(memories):
points = [
PointStruct(
id=str(i),
vector=model.encode(m["content"]).tolist(),
payload=m
)
for i, m in enumerate(memories)
]
client.upsert("jk_long_term_memory", points)
4. 隱私與安全
- 數據加密:敏感信息加密後再存儲
- 訪問控制:限制誰可以讀取記憶
- 刪除機制:支持記憶的永久刪除
def delete_memory(content: str):
"""刪除特定記憶"""
# 首先搜索
results = memory.search(content, top_k=1)
# 刪除匹配的記憶
for r in results:
client.delete("jk_long_term_memory", r.id)

Problem Solved: Why do AI agents need persistent memory?
In 2026, AI agents will no longer be single-conversation chatbots, but long-term partners who need to remember the past, understand context, and accumulate knowledge. The core values of OpenClaw are:
- Session persistence: Agent can remember previous decisions and operations across multiple sessions
- Contextual Continuity: Long-term memory allows agents to understand the user’s preferences, history, and project context
- Knowledge accumulation: As time goes by, the Agent needs to continuously learn and update the knowledge base
Problem: Traditional LLM conversations are based on context windows, and once the session ends, all memory is lost. How to let the Agent maintain memory at different times and in different sessions?
Solution: OpenClaw + Qdrant vector memory system.
Technical architecture: How to implement persistent memory
1. OpenClaw Memory Module
OpenClaw’s built-in memory system supports:
- Short-term memory: intra-session context (via
sessions_sendandsessions_history) - Long Term Memory: Persistent storage to an external vector database (Qdrant)
- Memory Search: Semantic search instead of keyword matching
2. Qdrant vector storage
**Why choose Qdrant? **
- Open source, high-performance vector database
- Supports embedding models such as BGE-M3, text-embedding-ada, etc. -Support real-time updates and queries
- Long-term knowledge base suitable for AI Agent
3. Memory process
用戶交互 → OpenClaw Agent → 提取關鍵信息 → 生成嵌入向量 → 存入 Qdrant

Practical steps
Step 1: Install necessary tools
# 安裝 Qdrant
curl -L https://github.com/qdrant/qdrant/releases/latest/download/qdrant-linux-amd64 -o qdrant
chmod +x qdrant
./qdrant
# 安裝 Python 嵌入模型
pip install qdrant-client sentence-transformers
Step 2: Configure the OpenClaw remember script
Create scripts/memory_recording.py:
#!/usr/bin/env python3
import json
from datetime import datetime
from qdrant_client import QdrantClient
from qdrant_client.models import PointStruct, VectorParams, Distance
from sentence_transformers import SentenceTransformer
class VectorMemoryRecorder:
def __init__(self, qdrant_url="http://localhost:6333", collection_name="jk_long_term_memory"):
self.client = QdrantClient(url=qdrant_url)
self.collection_name = collection_name
self.model = SentenceTransformer('BAAI/bge-m3')
# 確保集合存在
if not self.client.collection_exists(collection_name):
self.client.create_collection(
collection_name=collection_name,
vectors_config=VectorParams(size=1024, distance=Distance.COSINE)
)
def record_memory(self, content: str, metadata: dict = None):
"""記錄新記憶"""
if metadata is None:
metadata = {}
point = PointStruct(
id=str(datetime.now().timestamp()),
vector=self.model.encode(content).tolist(),
payload={
"content": content,
"timestamp": datetime.now().isoformat(),
"metadata": metadata
}
)
self.client.upsert(self.collection_name, [point])
print(f"✅ 記憶已記錄: {content[:50]}...")
def search_memory(self, query: str, top_k: int = 5, min_score: float = 0.5):
"""語義搜索記憶"""
query_vector = self.model.encode(query).tolist()
results = self.client.search(
collection_name=self.collection_name,
query_vector=query_vector,
limit=top_k,
score_threshold=min_score
)
return results
Step 3: Integrate in OpenClaw
Configure the memory function in SOUL.md:
# 記憶配置
記憶系統:向量記憶錄製
向量數據庫:Qdrant (jk_long_term_memory)
嵌入模型:BGE-M3
搜索方式:語義搜索而非關鍵字匹配

Step 4: Automate memory
Implement automatic memory recording in scripts/automated_memory.py:
def auto_record_interaction(agent, user_message, bot_response):
"""自動從交互中提取記憶"""
key_points = extract_key_points(user_message, bot_response)
for point in key_points:
memory.recorder.record_memory(
content=point,
metadata={
"source": "user_interaction",
"agent": agent,
"session": sessions_list()["active"][0]["sessionKey"]
}
)
Real case
Case 1: Project context memory
Scenario: When developing AI Agent, you need to remember the project history and user needs
# 記錄專案開始
memory.record_memory(
"專案:AI Agent 構建系統,目標是創建自主運行的 AI 代理,使用 OpenClaw 作為核心框架",
metadata={"type": "project", "status": "in_progress"}
)
# 記錄用戶需求
memory.record_memory(
"用戶需求:需要持久化記憶系統,支持跨會話查詢",
metadata={"type": "requirement", "priority": "high"}
)
# 搜索記憶
results = memory.search("專案目標", top_k=3)
for r in results:
print(f"相關記憶:{r.payload['content']} (相似度: {r.score:.2f})")
Case 2: User preference learning
Scenario: Learning the user’s communication style and preferences
# 自動記錄用戶偏好
def learn_user_preference(message):
if "喜歡" in message or "偏好" in message:
memory.record_memory(
content=f"用戶偏好:{message}",
metadata={"type": "preference", "source": "user_input"}
)
# 記錄後續交互
learn_user_preference("我喜歡深色主題")
learn_user_preference("請用繁體中文回覆"
Case 3: Knowledge accumulation
Scenario: Agent accumulates knowledge over time
# 週記錄
def weekly_memory_summary():
"""每週生成記憶摘要"""
summary = generate_weekly_summary()
memory.recorder.record_memory(
content=summary,
metadata={"type": "weekly_summary", "category": "project"}
)
Cheese’s Pro Tips
1. Memory layering strategy
Don’t store all information in a vector database. Suggestions:
- Short-term memory: stored directly in the context (built-in in OpenClaw)
- Medium Term Memory: Key operations in the last 7 days
- Long Term Memory: Permanently stored knowledge and decisions
# 分層記憶管理
def record_memory_with_level(content, level="long_term"):
if level == "short_term":
# 直接返回,不存儲
return
elif level == "mid_term":
# 存儲最近 7 天
if time_since_creation() < 7 days:
memory.recorder.record_memory(content)
elif level == "long_term":
# 永久存儲
memory.recorder.record_memory(content)
2. Embed model selection
Recommended model:
| Model | Advantages | Usage |
|---|---|---|
| BGE-M3 | Open source, multi-language, high quality | Common scenarios |
| text-embedding-ada | OpenAI proprietary | Requires cloud service |
| multilingual-e5 | Multi-language support | International projects |
3. Performance optimization
- Batch processing: Batch records instead of single records
- Incremental Update: Periodically update the embedding vectors of old memories
- Index Optimization: Use sharded indexes to improve search speed
# 批量記憶記錄
def batch_record_memories(memories):
points = [
PointStruct(
id=str(i),
vector=model.encode(m["content"]).tolist(),
payload=m
)
for i, m in enumerate(memories)
]
client.upsert("jk_long_term_memory", points)
4. Privacy and Security
- Data Encryption: Sensitive information is encrypted before storage
- Access Control: Restrict who can read the memory
- Delete Mechanism: Supports permanent deletion of memory
def delete_memory(content: str):
"""刪除特定記憶"""
# 首先搜索
results = memory.search(content, top_k=1)
# 刪除匹配的記憶
for r in results:
client.delete("jk_long_term_memory", r.id)
