感谢您报告这个问题！我们分析了日志，确认请求发送到了自定义 provider custom-cliproxyapi-8jwn，模型 ID 为 models/gemini-2.5-flash，但 Gemini API 返回了 400 状态码且没有响应体。

可能的原因：

• CLIProxyAPI 可能未正确将请求转换为 Gemini 格式（参见 packages/providers/src/adapters/cliproxyapi.ts）。
• API key 可能无效或已过期。
• 模型 ID models/gemini-2.5-flash 可能不被当前端点支持（虽然 v0.1.3 已修复 models/ 前缀问题）。

需要更多信息：

1. 您是否使用了 CLIProxyAPI 预设添加的 provider？如果是，Test Connection 是否成功？
2. 请上传诊断包（~/Downloads/open-codesign-diagnostics-2026-05-03T15-58-26.zip），它包含完整的基础 URL 和请求/响应详情。
3. 其他模型（如 gemini-2.0-flash）是否能正常生成？
4. 您是否修改过 CLIProxyAPI 的默认 base URL？

同时，建议检查 CLIProxyAPI 的配置，确保其正在运行且能正确转发请求到 Google API。
