After configuring a custom AI model, the corresponding model option does not appear

[Yakumo-Yukari]

After successfully configuring the custom AI model, the corresponding model selection does not appear in the AI session box.

I tried using multiple API paths, including base url/v1, base url/v1/chat/completions, and base url/v1/anthropic, but all returned the error: Failed to connect to custom API: Failed to fetch. However, the same model interface works properly when integrated into other IDEs.
