The “OpenAI API Key” and “Override OpenAI Base URL” text fields do not accept keyboard input

Support Bug Reports

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In Cursor Settings → Models → API Keys, the “OpenAI API Key” and
“Override OpenAI Base URL” text fields do not accept keyboard input
(typing). Paste (Ctrl+V) also often fails. The Base URL override toggle
works; the “Use OpenAI API key” enable control only appears after a key
is saved, but I cannot enter a key into the field.

Steps to Reproduce

  1. Open Cursor Settings → Models
  2. Expand API Keys
  3. Click “Enter your OpenAI API Key” or the Base URL text box
    (with Override OpenAI Base URL enabled)
  4. Try to type or paste a value

Expected Behavior

Fields accept typing/paste and save the key / custom base URL.
Actual: Caret may appear but characters cannot be entered; fields remain
empty / stuck on https://api.openai.com/v1.

Does this stop you from using Cursor

Hey there,
Those API Key / Base URL fields not accepting click or paste on 3.15.x isn’t intended.

Workaround: turn the toggle on, click nearby in Settings → Models, then press Tab until the field is focused - typing and Ctrl+V work after that.

Merging into the main thread: [Regression] Models: OpenAI API Key / Base URL inputs not editable in 3.15.6. I’ll post updates there when there’s news.
