Please complete the following information): 请补全以下内容

• OS: Linux, Fedora 40 KDE
• Browser: Firefox 130.0.1 (64-bit)
• Extension Version: 2.5.8 (Latest)

I double checked that model-key-endpoint are fine via pure python request

the api url should be complete (with /chat/completions) https://openrouter.ai/api/v1/chat/completions

Oh, I see! Thanks

I checked, there was a default value with completions endpoint, but I overlooked it once pasted my url

Maybe we can add a hint here? src/_locales/en/main.json:

{
  "Custom Model API Url": "Custom Model API Url (chat completions endpoint)",
}
