 # 待测试
 
+- 管理后台模型渠道新增 Sub2API 兼容模式和图片返回格式配置；选择 Sub2API 后，图片生成/编辑代理会自动携带 `response_format: "url"`，并支持带 `/v1` 的 OpenAI 兼容 Base URL 不重复拼接。需要用真实 Sub2API Key 验证文本、生图、图生图/编辑图三类请求。
+
 - 外部软件可通过 URL 查询参数 `baseUrl`/`baseurl` 和 `apiKey`/`apikey` 跳转到前端；读取后会从地址栏移除这些参数，后台允许自定义渠道时会自动切到自定义渠道、填入配置并打开配置弹窗，未允许时会打开配置弹窗并提示无法导入。
 - 生图工作台和画布生图会把参考图按当前顺序显示为 `图片1`、`图片2` 等编号，并在图生图请求的实际提示词中注入编号说明；需要验证 `/image` 参考图排序、画布配置节点输入顺序和画布助手参考图编号一致。
 - GPT Image 生图请求会在前端把 `9:16`、`16:9` 等比例转换成合法 `WIDTHxHEIGHT` 尺寸，并在非法尺寸时直接显示中文错误，避免上游返回 `invalid_value Invalid size`。

+Sub2API 接入建议：在管理员设置的模型渠道中新增渠道，接口兼容模式选择 `Sub2API`，`baseUrl` 填 Sub2API 提供的 OpenAI 兼容地址（例如 `https://你的域名/v1`），`apiKey` 填 Sub2API 生成的密钥，并配置该 key 可用的模型。图片生成/编辑会自动携带 `response_format: "url"`，前端仍兼容 URL 与 Base64 两种返回。
