- 用量页显示 API Key 余额：DeepSeek、Kimi、OpenRouter、硅基流动按官方接口自动查询；自定义供应商可以在编辑器里填「余额查询地址」和「余额字段」（CLI：
balance=/balance.path=），开着的每个 Key 都会各查一次。magpie provider <id>也会显示余额。(#40) - Codex 走 magpie 时，/model 里的官方 GPT 模型保留 Codex 自己的模型信息（图片输入、上下文窗口、工具），之前被当成第三方模型处理，只能输入文字。
- The Usage page shows what is left on an API key: DeepSeek, Kimi, OpenRouter and SiliconFlow are asked automatically; a custom provider can set a Balance URL and field in the editor (
balance=/balance.path=in the CLI), and each key it has on is asked.magpie provider <id>prints it too. (#40) - With Codex routed through magpie, the official GPT models in /model keep what Codex knows of them (image input, context window, tools); they were treated as third-party models, text only.
