Can you add use Model of antigravity like use Github copilot?

Context (who is affected and when)

I test RooCode on AntiGravity but have no model to use

Desired behavior (conceptual, not technical)

I test RooCode on AntiGravity but have no model to use

I'd like to help with this issue, but I need some clarification to ensure I understand the request correctly. Could you please provide more details on the following:

1. What is AntiGravity IDE? Is it a VS Code fork, a standalone IDE, or something else? A link to the AntiGravity IDE website or documentation would be helpful.

2. Is Roo Code currently installable in AntiGravity? Since Roo Code is a VS Code extension, does AntiGravity support VS Code extensions?

3. What do you mean by "no model to use"? Are you referring to:

   • LLM provider models (like OpenAI, Anthropic, etc.) not appearing in the dropdown?
   • A specific built-in model that AntiGravity provides that you want Roo Code to use?
   • Something else?

4. How does GitHub Copilot relate to this request? When you mention "use Model of antigravity like use Github copilot", are you asking for Roo Code to use the same model/API that GitHub Copilot uses within AntiGravity?

5. What error messages or behavior do you see? If you can share screenshots or error logs, that would help diagnose the issue.

Please tag @roomote in your response with these details, and I'll be happy to propose an implementation plan once I understand the requirements better.

@roomote It's a VS Code fork IDE. RooCode can install as an extension on AntiGravity. no model to use mean that I want to use Antigravity models like when I use Github Copilot models in RooCode, I can choose models of Copilot in the dropdown.

In the second image, I can use copilot model in extension. The first image is Roo Code in Antigravity, I think it doesn't support to use model of Antigravity so I hope you can add this feature to Roo Code

Thanks for the clarification! I understand now - you want Roo Code to show AntiGravity IDE's built-in models in the VS Code LM dropdown, similar to how GitHub Copilot models appear when running in regular VS Code.

I've looked at how Roo Code integrates with VS Code's Language Model API (vscode.lm). Currently, models are fetched using vscode.lm.selectChatModels({}), which returns all language models registered by extensions in the VS Code environment.

Key questions to help with implementation:

1. Does AntiGravity IDE register its models through the VS Code Language Model API (vscode.lm)? If so, they should automatically appear in the "VS Code LM" provider dropdown.

2. If AntiGravity uses a different mechanism to expose its models (like a custom API or extension API), could you point me to any documentation or code examples? This would help me understand how to integrate with AntiGravity's model system.

3. When you select "VS Code LM" as the provider in Roo Code while running in AntiGravity, do you see any models at all, or is the dropdown completely empty?

4. Is there an AntiGravity extension or API that provides access to its language models that we could integrate with?

I'll explore potential implementation approaches and will open a PR to share progress once I have a clearer path forward.
