先贴配置文件：

  "models": {
    "providers": {
      "xxx": {
        "baseUrl": "https://api2.aigcbest.top/v1",
        "apiKey": "你自己的api",
        "api": "anthropic-messages",
        "models": [
          {
            "id": "gemini-3-flash-preview-nothinking",
            "name": "gemini-3-flash-preview-nothinking",
            "api": "openai-completions",
            "reasoning": true,
            "input": [
              "text",
              "image"
            ],
            "cost": {
              "input": 0,
              "output": 0,
              "cacheRead": 0,
              "cacheWrite": 0
            },
            "contextWindow": 200000,
            "maxTokens": 8192
          }
        ]
      }
    }
  },
  "agents": {
    "defaults": {
      "model": {
        "primary": "xxx/gemini-3-flash-preview-nothinking"
      },
      "workspace": "/root/.openclaw/workspace",
      "compaction": {
        "mode": "safeguard"
      },
      "maxConcurrent": 4,
      "subagents": {
        "maxConcurrent": 8
      }
    }
  },

第三行的xxx和agents.defaults.model.primary中的xxx必须一样，primary中的xxx相当于从models.providers里面选择了一个分类

网上大部分配置文件没有openai-completions，博主亲测不加无法使用api
