Custom OpenAI Responses relay does not append /v1 when fetching models

English

What happened

When a custom OpenAI Responses-compatible relay is configured with a root URL such as:

http://relay.example:3000

the connection test succeeds, but updating the model catalog fails.

Maka requests:

GET /models

However, the relay provides the OpenAI-compatible model list at:

GET /v1/models

Cherry Studio works with the same configuration because it automatically appends /v1 when the base URL does not contain an API version. OpenAI's standard endpoints are also versioned:

GET  /v1/models
POST /v1/responses

Expected behavior

We should clarify whether the configured URL is a host root or a complete API base URL, and use the same URL normalization rule for model discovery and Responses requests.

Environment

• Maka: 0.1.11
• Surface: Desktop
• OS: Windows

问题描述

配置自定义 OpenAI Responses 兼容中转站时，如果服务地址填写为根地址：

http://relay.example:3000

连接测试可以成功，但更新模型目录失败。

Maka 当前请求：

GET /models

而该中转站的 OpenAI 兼容模型接口为：

GET /v1/models

相同配置在 Cherry Studio 中可以使用，因为当地址不包含 API 版本时，它会自动补充 /v1。OpenAI 的标准接口也包含版本前缀：

GET  /v1/models
POST /v1/responses

期望行为

需要明确配置地址表示主机根地址还是完整 API Base URL，并让模型发现和 Responses 请求使用一致的 URL 处理规则。

环境

• Maka：0.1.11
• 使用端：Desktop
• 系统：Windows
