The "chatLanguageModels.json" file allows for the option to inherit from the default profile.

[ProudRabbit]

Summary

Currently in multiple profiles, chatLanguageModels.json will not inherit the default settings.
When chatLanguageModels.json in a profile is empty, the settings in the default chatLanguageModels.json will not be inherited.

Expected Behavior

• Either chatLanguageModels.json follows the same profile-inheritance model as
  other user resources (a profile can choose "Use Default" and fall back to
  User\chatLanguageModels.json),
• or the file is shared/merged across profiles by default.

Actual Behavior

• Default profile reads User\chatLanguageModels.json → custom models appear. ✅
• Any non-default profile reads User\profiles\<profileId>\chatLanguageModels.json
  which is auto-created as [] → custom models disappear. ❌
• The Profiles manager UI does not list chatLanguageModels.json as a
  toggleable/inheritable resource.

Steps to Reproduce

1. Create a non-default profile (e.g. via Profiles: Manage Profiles).
2. In the Default profile, add a custom endpoint to
   C:\Users\<user>\AppData\Roaming\Code\User\chatLanguageModels.json.
3. Switch to the non-default profile, restart VSCode ,open Chat → "Switch Model".
4. Result: the custom models are missing.

Note: If you do not restart VSCode, the custom model will not be lost.

Workarounds tried

• Copying the file content manually into each
  User\profiles\<id>\chatLanguageModels.json → works, but must be re-synced
  manually on every change.
