Current State / 当前状态

配置添加Opencode Go的Qwen 3.7 MAX模型，使用Anthropic (Messages) API格式进行测试正常：
✅ 测试成功（延迟 9.72秒）
响应内容: Hello AxonHub! It's great to meet you. I am Qwen (also known as Tongyi Qianwen), a large language model developed by Alibaba Group's Tongyi Lab. How can I help you today?

使用OpenAI Chat Compoletions API格式进行测试异常：
Model qwen3.7-max is not supported for format oa-compat

Problem or Bottleneck / 问题或瓶颈

目前只能把服务商设置为Anthropic，然后使用Opencode Go的端点和key，才能正常使用他们提供的Qwen 3.7 MAX，但是这样做的话，在服务商显示上就是Anthropic（但本质不是），这导致了不够优雅

Proposed Optimization / 优化方案

方案1：只需要给服务商Opencode Go的API格式加上Anthropic (Messages)
方案2：提供自定义服务商名字和logo的接口

Expected Benefit / 期望收益

希望Opencode Go的Qwen 3.7 MAX的渠道能正常显示服务商
