 每个模型提供两种测试：
 
-- “验证模型”只访问模型列表并检查协议和路径，不生图、不扣费，用于定位模型 ID、凭证或配置错误。
-- “试生成”会在用户确认后真实生成一张低成本测试图，会消耗一次调用额度，用来证明创建任务、轮询状态和取得结果的完整链路可用。
+- “验证连接”只检查地址、API Key、模型列表、协议和路径，不生图、不扣费。部分聚合平台不会在 `/v1/models` 中公开媒体模型 ID，此时不能据此判定模型不可用。
+- “试生成”会在用户确认后真实生成一张低成本测试图并消耗一次调用额度。其成功结果是生图模型端到端可用性的最终依据，并会自动将该模型标记为已通过测试。
 
 总调度模型必须由用户从大语言模型池中指定。空间理解和生图各自支持两种方式：
