Issue #759 Resolution: "Requests Error" with Roocode VSCode Extension

Problem Summary

Users attempting to use "Gemini-3-Pro-Preview" with the Roocode VSCode extension are encountering "Requests Error" / "Service Unavailable" errors.

Root Causes

1. Invalid Model Name

The model name "Gemini-3-Pro-Preview" does not exist. This is causing the API requests to fail.

Valid model names include:

• gemini-1.5-flash (recommended for most use cases)
• gemini-1.5-flash-latest
• gemini-1.5-pro
• gemini-1.5-pro-latest
• gemini-2.0-flash (newest model)
• gemini-2.0-flash-001

2. Deprecated SDK

This repository (google-gemini/deprecated-generative-ai-python) is deprecated and will reach End-of-Life on November 30, 2025.

Solutions

Immediate Fix for Roocode Users

If you're using the Roocode VSCode extension:

1. Update your model configuration in Roocode settings:

   • Open VSCode Settings (Ctrl/Cmd + ,)
   • Search for "Roocode"
   • Find the model name setting
   • Change Gemini-3-Pro-Preview to a valid model name like:
     • gemini-2.0-flash (newest, recommended)
     • gemini-1.5-pro (more capable for complex tasks)
     • gemini-1.5-flash (faster, good for most tasks)

2. Verify your API key is valid:

   • Ensure your Google AI API key is correctly configured
   • Get your API key from: https://aistudio.google.com/app/apikey

Long-term Recommendation: Migrate to New SDK

All users should migrate to the new Google Generative AI SDK:

1. Uninstall the old SDK:

   pip uninstall google-generativeai

2. Install the new SDK:

   pip install google-genai

3. Update your code:

   Old SDK (deprecated):

   import google.generativeai as genai
   
   genai.configure(api_key="YOUR_API_KEY")
   model = genai.GenerativeModel("gemini-1.5-flash")
   response = model.generate_content("Hello")

   New SDK (recommended):

   from google import genai
   
   client = genai.Client(api_key="YOUR_API_KEY")
   response = client.models.generate_content(
       model="gemini-1.5-flash",
       contents="Hello"
   )

How to List Available Models

To see all currently available models, use:

import google.generativeai as genai

genai.configure(api_key="YOUR_API_KEY")

print("Models that support generateContent:")
for m in genai.list_models():
    if 'generateContent' in m.supported_generation_methods:
        print(f"  - {m.name}")

Or via REST API:

curl https://generativelanguage.googleapis.com/v1beta/models?key=YOUR_API_KEY

For Third-Party Tool Developers (Roocode, etc.)

If you're developing tools that integrate with Google's Gemini API:

1. Implement model name validation before making API requests
2. Provide users with a dropdown of valid model names instead of free-text input
3. Migrate to the new Google Gen AI SDK for better long-term support
4. Handle API errors gracefully with clear user-facing error messages
5. Keep model list updated as new models are released

Status

• Issue Type: Configuration Error (Invalid Model Name)
• Affected Component: Third-party VSCode extension (Roocode)
• SDK Status: Deprecated (EOL: November 30, 2025)
• Recommended Action: Update model name + Migrate to new SDK

---

Note: This issue is not a bug in the SDK itself, but rather a configuration issue in the third-party Roocode extension using an invalid model name. Since this SDK is deprecated, users should migrate to the new Google Generative AI SDK for continued support.
