创建配置文件 ~/.claude/settings.json
添加以下内容：

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.deepseek.com/anthropic",
    "ANTHROPIC_AUTH_TOKEN": "你的DeepSeek_API_Key",
    "ANTHROPIC_MODEL": "deepseek-v4-pro[1m]",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "deepseek-v4-pro[1m]",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "deepseek-v4-pro[1m]",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "deepseek-v4-flash",
    "CLAUDE_CODE_SUBAGENT_MODEL": "deepseek-v4-pro",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1",
    "CLAUDE_CODE_DISABLE_NONSTREAMING_FALLBACK": "1",
    "CLAUDE_CODE_EFFORT_LEVEL": "max"
  }
}

替换 API Key：一定要记得把 “你的DeepSeek_API_Key”，换成你真实的 DeepSeek API Key。

以上配置支持cluade code CLI和vs code claude code插件。
