配置 Hermes Agent 使用 DeepSeek V4.1 Flash 模型：

注意事项：以下配置中的 <API_KEY> 需要替换为从 https://platform.wcode.net 获取（创建）的 API Key

方式一：交互式配置

在命令行输入 hermes model，然后选择 Custom endpoint 选项，根据交互式命令引导，分别配置以下信息：

• API base URL：https://wcode.net/api/gpt/v1
• API Key：<API_KEY>
• Model：deepseek/deepseek-v4.1-flash

方式二：手动配置

修改 config.yaml（通常位于~/.hermes/config.yaml）

model:
  default: "deepseek/deepseek-v4.1-flash"
  provider: custom
  base_url: "https://wcode.net/api/gpt/v1"
  api_key: "<API_KEY>"
  context_length: 1024000

配置完成后，就可以开始使用 Hermes Agent ~

注：以下安装和配置过程以 Ubuntu Server 24.04 (root 用户) + Node 22 安装 OpenClaw 🦞 2026.3.8 为例

安装 🦞 OpenClaw（龙虾），步骤如下：

1. 命令行执行 npm install -g openclaw@latest
2. 命令行执行 openclaw onboard --install-daemon
3. I understand this is personal-by-default and shared/multi-user use requires lock-down. Continue? 选择 yes
4. Onboarding mode 选择 QuickStart
5. Model/auth provider 选择 Skip for now
6. Default model 选择 Keep current (default: ...)
7. Select channel (QuickStart) 选择 Skip for now
8. Web search 选择 Skip for now
9. Configure skills now? (recommended) 选择 No
10. Enable hooks? （这是一个多选，按空格键可选中选项）按空格键选中 📝 command-logger 和 💾 session-memory 这两个选项，然后按回车键进入下一步
11. (如有) How do you want to hatch your bot? 选择 Hatch in TUI (recommended)

配置 🦞 OpenClaw（龙虾）使用 DeepSeek V4.1 Flash 模型：

注意事项：以下配置中的 <API_KEY> 需要替换为从 https://platform.wcode.net 获取（创建）的 API Key

推荐方式：修改 openclaw.json（通常位于~/.openclaw/openclaw.json）

找到openclaw.json的第一层级的models和agents属性（如果没有则在第一层级添加models和agents属性），改为如下配置：

{
  ...其他配置,

  "models": {
      "mode": "merge",
      "providers": {
          "wcode": {
              "baseUrl": "https://wcode.net/api/gpt/v1",
              "apiKey": "<API_KEY>",
              "api": "openai-completions",
              "models": [
                  {
                      "id": "deepseek/deepseek-v4.1-flash",
                      "name": "DeepSeek V4.1 Flash",
                      "reasoning": false,
                      "input": ["text"],
                      "contextWindow": 1024000,
                      "maxTokens": 8192
                  }
              ]
          }
      }
  },
  "agents": {
      "defaults": {
         "model": {
             "primary": "wcode/deepseek/deepseek-v4.1-flash"
         }
      }
  },

  ...其他配置
}

完成以上配置后，

1. 执行以下命令，即可通过命令行的方式开始对话：

openclaw tui

2. 执行以下命令，即可通过 Web 界面的方式开始对话：

openclaw dashboard

配置 OpenCode 使用 DeepSeek V4.1 Flash 模型：

推荐方式：修改 opencode.json（通常位于~/.config/opencode/opencode.json）

注意事项：以下配置中的 <API_KEY> 需要替换为从 https://platform.wcode.net 获取的 API Key

配置如下：

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "myprovider": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "wcode",
      "options": {
        "baseURL": "https://wcode.net/api/gpt/v1",
        "apiKey": "<API_KEY>"
      },
      "models": {
        "deepseek/deepseek-v4.1-flash": {
          "name": "DeepSeek V4.1 Flash"
        }
      }
    }
  }
}

完成以上配置后，执行以下命令，即可启动 OpenCode：

opencode

输入 /models，选择配置的 deepseek/deepseek-v4.1-flash 模型并在 OpenCode 中使用。
