CPA 配置如下 
openai-compatibility:
  - name: xxxx
    priority: 10
    base-url: xxxxx/v1
    api-key-entries:
      - api-key: xxxxx
    models:
      - name: gpt-5.5
        alias: ""
        thinking:
          levels: ["low", "medium", "high", "xhigh"]

已经按照 自定义供应商 中转站 提示不支持 xhigh · router-for-me/CLIProxyAPI · Discussion #2564 设置，但在 codex 中 /model 选择 gpt-5.5 xhigh 时报错：provider=openai model=gpt-5....
