Hi GitHub Copilot Team,

I am a Copilot Pro user. I am writing to report a significant feature disparity between the VS Code extension and the JetBrains IDE plugin.

The Issue:
In VS Code and the Web interface, I can successfully select and use the latest premium models like Claude and GPT-5.3. However, these models are completely missing from the model selector in PyCharm (JetBrains Plugin).

My Environment:
IDE: PyCharm 2025.3.2.1 (Latest)
Plugin: GitHub Copilot (Latest version updated)
Account: Copilot Pro Subscription

Attachments:

Request:
I expect a consistent experience across all supported IDEs. The current lag in model availability for JetBrains users is frustrating.

Could you please clarify when the JetBrains plugin will be updated to support the new model selector whitelist?

Best regards,
NineThoughts0521
