Two Kinds of AI Memory

AI memory has two audiences — the machine and the human. Most tools only address one:

	For the AI (what it knows)	For the Human (what you can review)
Goal	AI remembers preferences, decisions, context across sessions	You browse, search, and manage conversation history
Problem solved	"Why does it keep forgetting my coding style?"	"What did we discuss last Tuesday?"

MemoMind handles the AI side — it gives your coding agent persistent, structured, intelligent memory. For the human side, see Recall (our companion project for conversation history management).

Use both together for the complete experience.

The Problem

You've spent thousands of hours with AI — but it remembers nothing.

• Your coding AI is a stranger every morning. You spent 20 minutes explaining your architecture, your tech stack decisions, your naming conventions. Session ends. Tomorrow? "Hi, I'm Claude. How can I help you today?" From scratch. Again.
• Your ChatGPT/Gemini conversations are a graveyard. Hundreds of deep discussions — career advice, research brainstorms, debugging sessions — sitting in separate silos, unsearchable, unconnected, slowly forgotten by you too.
• Your daily life is invisible to AI. You tracked 5,000+ days of activities, habits, and achievements in your planner. Your AI knows none of it. It can't say "Last time you worked on this topic was 3 months ago" or "You tend to be most productive on Tuesday mornings."

The problem isn't intelligence — GPT-5, Claude, Gemini are brilliant. The problem is amnesia. Every session is a blank slate. Every AI is an isolated silo. Your years of digital life produce zero compounding value.

What if your AI could remember everything? Not just this session — but every conversation you've ever had, every decision you've made, every day you've lived?

Why Not Just Use CLAUDE.md?

Claude Code already has CLAUDE.md and MEMORY.md. But they have fundamental limitations:

	Claude Code Built-in	MemoMind
Storage	Plain Markdown files	PostgreSQL + pgvector + knowledge graph
Extraction	Manual — you write rules yourself	Automatic — LLM extracts facts from conversations
Retrieval	Full file loaded into context every time (wastes tokens)	4-way hybrid search, only relevant memories recalled
Cross-session	Static rules; append-only notes	Dynamic knowledge graph with entity linking + temporal relationships
Reasoning	No — just loads text	reflect synthesizes insights across all memories
Scalability	Breaks down at ~200 lines (context bloat)	Handles thousands of memories efficiently

They're complementary, not competing. CLAUDE.md is great for static project rules ("use tabs, not spaces"). MemoMind handles the dynamic knowledge that accumulates over time ("user tried Redis caching last week but switched to Memcached due to memory constraints").

The Solution

MemoMind gives your AI a persistent, local, intelligent brain. Not a chat log — a living knowledge graph that grows with every interaction, every imported conversation, every day of your life.

	Without MemoMind	With MemoMind
Session start	Blank slate, zero context	Recalls your preferences, past decisions, project context
500 ChatGPT conversations	Scattered across browser tabs, unsearchable	Unified knowledge graph, every fact extracted and linked
3 years of daily activities	Trapped in your planner app	Searchable timeline — AI knows your patterns and history
Cross-AI knowledge	ChatGPT doesn't know what you told Gemini	All conversations merged into one memory
Decision tracking	Lost when chat window closes	Stored as structured facts with source tracing
Cross-session reasoning	Impossible	reflect synthesizes insights across all memories
Privacy	Cloud-based, fragmented	100% local — nothing leaves your machine

You: "Let's use FastAPI instead of Express for this project"

Claude Code internally:
  → retain("Project migrating from Express to FastAPI")  # auto-stores

Next week, new session:
  → recall("project tech stack")                          # auto-retrieves
  → "Based on your previous decision, I'll use FastAPI..."

You don't do anything — the AI handles it all.

Architecture

Three Core Operations

Operation	What It Does	When AI Calls It
retain	Extract facts from conversation, store in vector DB	After learning something new about you
recall	4-way hybrid search (semantic + BM25 + graph + temporal)	Before responding, to check relevant history
reflect	Deep reasoning across all memories	For complex questions requiring synthesis

Memory Types

MemoMind organizes knowledge into four biomimetic memory pathways — modeled after how human memory actually works:

Type	What It Captures	Example	How It's Used
World	Objective facts about the user and environment	"User prefers Python over R"	Shapes recommendations and defaults
Experience	Events the agent participated in	"Last session we debugged the auth module"	Provides continuity across sessions
Observation	Patterns auto-synthesized from behavior	"User consistently uses functional style"	Refines understanding over time
Mental Model	Learned understanding of complex topics	"This codebase follows hexagonal architecture with ports and adapters"	Enables deeper reasoning about project context

Unlike flat key-value stores, these types form a knowledge graph — entities are linked by relationships, creating retrieval pathways that go far beyond simple keyword matching.

Memory Evolution

Observations don't just accumulate — they evolve. The consolidation engine automatically merges, updates, and refines observations as new facts arrive:

Each memory bank has a configurable mission that controls how the consolidation engine synthesizes observations — from simple detail tracking to structured task-level experience records with procedures, lessons learned, and user preferences.

Quick Start

Prerequisites

• NVIDIA GPU (optional but recommended for local embeddings)
• An LLM API key (MindCraft for China users / OpenRouter for international)
• Windows: Python 3.11+, Visual Studio Build Tools (for pgvector compilation)
• Linux/macOS: Python 3.11+, PostgreSQL 17+

Option A: Windows Native (Recommended for Windows users)

Runs entirely on Windows — no WSL, no virtual machines. Most stable option.

Step 1 — Clone and set up Python venv

git clone https://github.com/24kchengYe/MemoMind.git
python -m venv D:\pythonPycharms\memomind-env

Step 2 — Install dependencies

# Install hindsight-api (skip uvloop — Windows doesn't support it)
pip install hindsight-api-slim --no-deps
pip install pg0-embedded sentence-transformers torch --index-url https://download.pytorch.org/whl/cu124
# Install remaining deps (see requirements-win.txt or install all from hindsight-api-slim metadata)

Step 3 — Set up PostgreSQL 17 + pgvector

# Download PG 17 portable: https://www.enterprisedb.com/download-postgresql-binaries
# Extract to e.g. D:\memomind-pg\pgsql\
# Initialize and start:
pg_ctl initdb -D D:\memomind-pg\data -U hindsight -A trust
pg_ctl start -D D:\memomind-pg\data -o "-p 5433"

# Build and install pgvector (requires Visual Studio Build Tools):
git clone https://github.com/pgvector/pgvector.git
# In VS Developer Command Prompt:
set PGROOT=D:\memomind-pg\pgsql
nmake /F Makefile.win && nmake /F Makefile.win install

# Create database with vector extension:
createdb -h localhost -p 5433 -U hindsight hindsight
psql -h localhost -p 5433 -U hindsight -d hindsight -c "CREATE EXTENSION vector;"

Step 4 — Configure and start

# Edit serve.py — set LLM_API_KEY, LLM_BASE_URL, LLM_MODEL
# Apply patches:
python patch_hindsight.py

# Start the server:
python serve.py          # API at http://localhost:19999
pythonw dashboard.py     # Dashboard at http://localhost:9999

Step 5 — Register MCP in Claude Code

claude mcp add --scope user --transport stdio memomind \
  -- D:\memomind-env\Scripts\python.exe D:\memomind-env\mcp_stdio.py

Step 6 — (Optional) Auto-start on boot

# Create a Windows Scheduled Task, or copy to Startup:
copy start-memomind.vbs "%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\"

Option B: WSL2 / Linux (Recommended for Linux users)

Uses WSL2 on Windows or runs natively on Linux. Leverages systemd for service management.

Step 1 — Clone and install

git clone https://github.com/24kchengYe/MemoMind.git

# On Linux or inside WSL:
cd MemoMind
sudo bash install.sh

Step 2 — Configure your LLM API key

sudo nano /opt/memomind-env/serve.py
# Set LLM_API_KEY, LLM_BASE_URL, LLM_MODEL (see "Supported LLM Providers" below)

Step 3 — Start the service

sudo systemctl start memomind

Step 4 — Register MCP in Claude Code

# From Windows (if using WSL):
claude mcp add --scope user --transport stdio memomind \
  -- wsl -d Ubuntu -u memomind -e //opt/memomind-env/mcp-entry.sh

# From Linux (native):
claude mcp add --scope user --transport stdio memomind \
  -- /opt/memomind-env/bin/python3 /opt/memomind-env/mcp_stdio.py

Step 5 — (Optional) Auto-start & Dashboard

# WSL auto-start (run from Windows):
copy keep-wsl-alive.vbs "%APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\"

# Dashboard (run from Windows, or Linux with GUI):
pythonw dashboard.py  # Opens at http://localhost:9999

Verify (both options)

curl http://localhost:19999/health
# → {"status":"healthy","database":"connected"}

Supported LLM Providers

The LLM is only used for fact extraction (not for chatting). MemoMind supports any OpenAI-compatible API. Two deployment modes:

Mode A: China Direct (no proxy needed) — Recommended for China users

Use a domestic OpenAI-compatible API gateway. No VPN, no proxy, no extra configuration:

Provider	Base URL	Recommended Model	Notes
MindCraft	https://api.mindcraft.com.cn/v1	deepseek-chat, qwen-flash	200+ models, pay-per-use
DeepSeek	https://api.deepseek.com/v1	deepseek-chat	Official DeepSeek API
SiliconFlow	https://api.siliconflow.cn/v1	Various open-source models	Free tier available

# In serve.py — just set these three lines:
LLM_API_KEY = "your-api-key"
LLM_BASE_URL = "https://api.mindcraft.com.cn/v1"
LLM_MODEL = "deepseek-chat"
NEEDS_PROXY = False  # No proxy needed

Mode B: International APIs (proxy required)

For OpenRouter, OpenAI, Anthropic, etc. Requires a proxy bridge (proxy-bridge.py) to route WSL traffic through your Windows proxy:

Provider	Base URL	Recommended Model
OpenRouter	https://openrouter.ai/api/v1	qwen/qwen3.5-9b ($0.05/1M tokens)
OpenAI	https://api.openai.com/v1	gpt-4.1-nano
Groq	https://api.groq.com/openai/v1	llama-3.3-70b-versatile (ultra-fast)

# In serve.py:
LLM_API_KEY = "sk-..."
LLM_BASE_URL = "https://openrouter.ai/api/v1"
LLM_MODEL = "qwen/qwen3.5-9b"
NEEDS_PROXY = True  # Routes through proxy-bridge.py → Clash

Proxy bridge setup (for Mode B only)

MemoMind includes proxy-bridge.py — a lightweight TCP forwarder that runs on Windows and bridges WSL to your local proxy (e.g., Clash):

# Start the bridge (binds 0.0.0.0:12080 → 127.0.0.1:2080)
pythonw proxy-bridge.py

# WSL can now reach your proxy via {Windows_IP}:12080
# This is automatically configured in serve.py when NEEDS_PROXY = True

To auto-start, uncomment the proxy-bridge line in keep-wsl-alive.vbs.

Also supported (any OpenAI-compatible API)

Ollama (fully local, no API key needed), Groq, LM Studio, and more. For non-OpenAI-compatible providers (Anthropic, Gemini), set llm_provider in serve.py to "anthropic" or "gemini".

Integration Options

MemoMind can be integrated in multiple ways beyond MCP:

Option 1: MCP (Recommended for Claude Code)

Zero-code setup — Claude Code automatically calls retain / recall / reflect via MCP protocol. See Quick Start above.

Option 2: Python SDK

pip install hindsight-client  # Install the client library

from hindsight_client import HindsightClient

client = HindsightClient(base_url="http://localhost:8888")

# Store a memory
client.retain("default", "User prefers FastAPI over Express for new projects")

# Recall relevant memories
results = client.recall("default", "What framework should I use?")
for memory in results:
    print(memory.text, memory.relevance_score)

# Deep reflection across all memories
insight = client.reflect("default", "What patterns do you see in my tech choices?")
print(insight)

Option 3: REST API

# Health check
curl http://localhost:8888/health

# List memories
curl http://localhost:8888/v1/default/banks/default/memories/list

# Recall (semantic search)
curl -X POST http://localhost:8888/v1/default/banks/default/memories/recall \
  -H "Content-Type: application/json" \
  -d '{"query": "user preferences", "max_tokens": 4096}'

# Reflect
curl -X POST http://localhost:8888/v1/default/banks/default/reflect \
  -H "Content-Type: application/json" \
  -d '{"query": "Summarize what you know about this user"}'

Per-User Memory Isolation

Use separate memory banks to isolate memories per user, project, or context:

# Create a bank per user
client.create_bank("user-alice", name="Alice's Memories")
client.create_bank("user-bob", name="Bob's Memories")

# Each user's memories are completely isolated
client.retain("user-alice", "Alice prefers dark mode and Vim keybindings")
client.retain("user-bob", "Bob uses VS Code with default settings")

# Recall only searches within the specified bank
alice_prefs = client.recall("user-alice", "editor preferences")
# → Only returns Alice's preferences, not Bob's

Backup & Export — Future-Proof Your Digital Twin

AI memory systems will keep evolving — today it's MemoMind, tomorrow it could be something better from OpenAI, Anthropic, or the next startup. The memories you accumulate now are the real asset, not the tool.

MemoMind treats your memory data as portable by design. Start building your digital twin's knowledge base today — every preference, decision, and experience you teach your AI is exported in an open format, ready to migrate whenever you want.

Manual export — Click the 💾 button in the dashboard toolbar to download a complete JSON backup of all memories, entities, tags, relationships, and graph data.

Automated weekly backup — A Python script that exports all memories and pushes to a private GitHub repo:

# 1. Create a private repo for backups
gh repo create your-username/memomind-backup --private

# 2. Set up the backup directory
mkdir memomind-memory && cd memomind-memory
git init && git remote add origin https://github.com/your-username/memomind-backup.git
cp /path/to/MemoMind/backup-memomind.py .

# 3. Edit backup-memomind.py — set BACKUP_DIR to this directory

# 4. Test manually
python backup-memomind.py

# 5. Schedule weekly (Windows Task Scheduler)
# Action: pythonw.exe  Arguments: path\to\backup-memomind.py
# Trigger: Weekly, Sunday 3:00 AM

Export format — portable JSON, not tied to any system:

{
  "version": "1.0",
  "format": "memomind-export",
  "memories": [
    {
      "text": "User prefers FastAPI over Express",
      "entities": ["FastAPI", "Express"],
      "tags": ["tech-stack"],
      "date": "2026-03-15T...",
      "fact_type": "world",
      "source_memory_ids": [],
      "history": []
    }
  ],
  "graph": { "nodes": [...], "edges": [...] }
}

Your memories are yours. When a better system comes along, take everything with you — text, entities, timestamps, tags, relationships, provenance. No vendor lock-in, no data hostage. Start accumulating your AI's knowledge today; it only gets more valuable over time.

Resource Usage

Measured with ~7,600 memories across 3 banks:

Component	Idle	Active
PostgreSQL 17	~100MB RAM	~300MB RAM
MemoMind Server (serve.py)	~2GB RAM	~2GB RAM
MCP process (per session)	~1.5GB RAM	~1.5GB RAM
GPU (embeddings)	0	~500MB VRAM (burst)
Disk (PostgreSQL data)	~660MB	Grows with memories
Network	0	LLM API calls on retain

Tip: Close unused Claude Code sessions to free MCP process memory. Each open session loads its own embedding model (~1.5GB).
Windows native uses less RAM than WSL2 (no virtualization overhead).

Troubleshooting

MCP not connecting

# Windows native:
curl http://localhost:19999/health
# Check if serve.py and PostgreSQL are running

# WSL mode:
wsl -d Ubuntu -e systemctl status memomind

WSL shuts down automatically (WSL mode only)

• Ensure keep-wsl-alive.vbs is in your Windows Startup folder
• Or: wsl -d Ubuntu -e bash -c "sleep infinity" &
• Consider switching to Windows native mode for better stability

Models fail to download

export HF_ENDPOINT=https://hf-mirror.com  # Use China mirror

China users

• Embedding models download from hf-mirror.com automatically — no VPN needed

两种 AI 记忆

AI 记忆服务两种受众——机器和人类：

	给 AI 的记忆（它知道什么）	给人类的记忆（你能查什么）
目标	AI 跨会话记住偏好、决策、上下文	你浏览、搜索、管理对话历史
解决的问题	"为什么它老忘我的编码风格？"	"上周二我们讨论了什么？"

MemoMind 负责 AI 侧——给编程智能体持久、结构化、智能的记忆。人类侧请看 Recall（对话历史管理工具）。

两者搭配使用效果最佳。

---

问题

你和 AI 共度了数千小时——但它什么都不记得。

• 你的编程 AI 每天早上都是陌生人。 你花 20 分钟解释架构、技术选型、命名规范。会话结束。明天？"你好，我是 Claude，有什么可以帮你？" 从零开始。又一次。
• 你的 ChatGPT/Gemini 对话是一片墓地。 几百条深度讨论——职业建议、科研头脑风暴、debug 过程——分散在不同平台，无法搜索，互不连通，连你自己也渐渐忘了。
• 你的日常生活对 AI 完全不可见。 你在 DayLife 里记录了 5000 多天的活动、习惯和成就。AI 一无所知。它说不出*"你上次做这个课题是 3 个月前"或"你周二上午效率最高"*。

问题不在于智能——GPT-5、Claude、Gemini 都很聪明。问题在于失忆。每次会话都是白纸。每个 AI 都是孤岛。你数年的数字生活，产生了零复利价值。

如果你的 AI 能记住一切呢？ 不只是这次会话——而是你的每一次对话、每一个决策、每一天的生活？

为什么 CLAUDE.md 不够？

Claude Code 已有 CLAUDE.md / MEMORY.md 内置记忆，但有根本局限：

	Claude Code 内置	MemoMind
存储	纯 Markdown 文件	PostgreSQL + pgvector + 知识图谱
提取	手动写规则	LLM 自动从对话中提取事实
检索	每次全量加载（浪费 token）	4 路混合搜索，只召回相关记忆
推理	无	reflect 跨所有记忆综合推理
扩展性	~200 行后上下文膨胀	高效处理数千条记忆

两者互补：CLAUDE.md 适合静态项目规则（"用 tab 不用空格"）；MemoMind 处理随时间积累的动态知识（"用户上周试了 Redis 缓存但因内存问题换成了 Memcached"）。

解决方案

MemoMind 赋予你的 AI 一个持久、本地、智能的大脑。不是聊天记录——而是一个随着每次交互、每次导入的对话、每一天的生活不断生长的知识图谱。

	没有 MemoMind	有 MemoMind
会话开始	一片空白，零上下文	自动回忆你的偏好、历史决策、项目背景
500 条 ChatGPT 对话	散落在浏览器标签里，无法搜索	统一知识图谱，每条事实自动提取并关联
3 年日常活动	困在记录 App 里	可搜索时间线——AI 了解你的模式和历史
跨 AI 知识	ChatGPT 不知道你跟 Gemini 说了什么	所有对话合并到一个记忆系统
决策追踪	关掉聊天窗口就丢了	结构化事实 + 原始对话溯源
跨会话推理	不可能	reflect 跨所有记忆综合分析
隐私	基于云，碎片化	100% 本地——数据不出你的电脑

📊 真实生产数据

架构

三大操作

四种记忆类型

类型	捕获什么	示例	作用
World（世界事实）	关于用户和环境的客观事实	"用户偏好 Python 而非 R"	影响推荐和默认行为
Experience（经历）	AI 参与过的事件	"上次会话调试了 auth 模块"	提供跨会话连续性
Observation（观察）	从行为中自动归纳的模式	"用户一直使用函数式风格"	持续优化理解
Mental Model（心智模型）	对复杂主题的深层理解	"这个代码库使用六边形架构"	支持更深层次的推理

这些类型构成知识图谱——实体通过关系链接，创建远超关键词匹配的检索路径。

记忆进化

Observation 不只是累积——它们会进化。巩固引擎自动合并、更新、精炼 observation：

每个记忆银行有可配置的 mission，控制巩固引擎的归纳方向——从简单的细节记录到结构化的任务级经验（包含步骤、教训、偏好）。

使用场景

• 编程助手 — 跨会话记住项目架构、编码风格、命名规范、技术栈决策
• 项目管理 — 追踪决策、截止日期、阻塞点；跨所有上下文反思项目风险
• 代码审查 — 回忆历史审查反馈模式；了解代码库中哪些区域脆弱
• 调试 — 记住之前试过什么、什么有效、什么无效——不再重复失败的方法
• 团队入职 — 新成员的 AI 立即继承项目积累的知识

核心能力

• 100% 本地 — PostgreSQL + 嵌入模型运行在你的机器上，数据不出机器
• 零手动操作 — AI 自主决定记什么、什么时候回忆
• GPU 加速 — 使用 NVIDIA GPU 加速本地嵌入和重排序
• 4 路混合检索 — 语义相似度 + BM25 关键词 + 知识图谱 + 时序搜索（关键词 20ms / 语义 400ms）
• 嵌入模型 — bge-m3（1024 维），消费级 GPU 50ms/条
• 深度反思 — reflect 跨所有记忆综合推理，不只是检索
• 心智模型 — 构建对复杂主题的演化理解，不只是孤立的事实
• 元数据过滤 — 为记忆添加标签，实现按项目/按用户隔离
• 多 LLM 支持 — OpenAI、Anthropic、Gemini、Groq、Ollama、LM Studio 等
• 生活轨迹 — 自动导入 DayLife 活动记录（按事件粒度），智能增量同步，断电多天也不丢
• AI 对话导入 — 导入 ChatGPT + Gemini 对话历史到知识图谱
• 双搜索模式 — 面板中一键切换关键词搜索和语义召回
• 无限滚动 — 记忆流和时间线懒加载，数千条记忆也流畅浏览
• 可视化面板 — 在 http://127.0.0.1:9999 浏览和搜索所有记忆
• 开机自启 — Windows 计划任务 或 systemd 服务，重启后自动恢复

备份与导出 — 面向未来的数字分身

AI 记忆系统会不断进化——今天是 MemoMind，明天可能是 OpenAI、Anthropic 或下一个创业公司的方案。你积累的记忆才是真正的资产，工具只是载体。

从现在开始培养你的数字分身——每一个偏好、决策、经验都以开放格式导出，随时可以迁移。

手动导出 — 点击面板工具栏的 💾 按钮，一键下载完整 JSON 备份（含所有记忆、实体、标签、关系图谱）。

每周自动备份 — Python 脚本自动导出并推送到私密 GitHub 仓库：

# 1. 创建私密仓库
gh repo create your-username/memomind-backup --private

# 2. 配置备份目录
mkdir memomind-memory && cd memomind-memory
git init && git remote add origin https://github.com/your-username/memomind-backup.git
cp /path/to/MemoMind/backup-memomind.py .

# 3. 手动测试
python backup-memomind.py

# 4. 设置 Windows 定时任务（每周日凌晨 3:00）

你的记忆属于你。 以后出现更好的系统，带走一切——文本、实体、时间戳、标签、关系链路、来源溯源。没有厂商锁定，没有数据绑架。今天开始积累，时间越久越有价值。

快速开始

前置条件

• NVIDIA GPU（可选，推荐用于本地嵌入）
• LLM API 密钥（国内推荐 MindCraft / 国际推荐 OpenRouter）
• Windows 用户: Python 3.11+，Visual Studio Build Tools（编译 pgvector）
• Linux 用户: Python 3.11+，PostgreSQL 17+

方案 A：Windows 原生安装（推荐）

无需 WSL，无需虚拟机，最稳定。详见英文 Quick Start — Option A。

# 核心流程：
git clone https://github.com/24kchengYe/MemoMind.git
python -m venv memomind-env
pip install hindsight-api-slim --no-deps  # 跳过 uvloop（Windows 不支持）
# 安装 PG 17 便携版 + 编译 pgvector + 配置 serve.py + 注册 MCP

方案 B：WSL2 / Linux 安装

适合 Linux 原生环境或偏好 WSL 的用户。详见英文 Quick Start — Option B。

git clone https://github.com/24kchengYe/MemoMind.git
cd MemoMind && sudo bash install.sh
sudo systemctl start memomind
claude mcp add --scope user --transport stdio memomind \
  -- wsl -d Ubuntu -u memomind -e //opt/memomind-env/mcp-entry.sh

LLM 配置

MemoMind 支持两种部署模式，在 serve.py 和 mcp_stdio.py 中配置：

模式 A：国内直连（推荐）— 使用 MindCraft、DeepSeek 官方 等国内 API，无需代理：

LLM_API_KEY = "your-key"
LLM_BASE_URL = "https://api.mindcraft.com.cn/v1"
LLM_MODEL = "deepseek-chat"
NEEDS_PROXY = False

模式 B：走代理— 使用 OpenRouter 等国际 API，通过 proxy-bridge.py 桥接 WSL 到 Clash 代理

中国用户提示

• 嵌入模型自动从 hf-mirror.com 下载，无需 VPN
• 推荐使用模式 A（国内直连），retain 速度约 10-15 秒（vs 走代理 40-50 秒）
