 4. **OpenAI** - Default fallback if `OPENAI_API_KEY` is configured
 
 The implementation includes:
 - Environment variable check for `GEMINI_3_PRO_API_KEY`
 - Creation of Google Generative AI client using `createGoogleGenerativeAI()`

 - Error handling with fallback to the next available provider
+- Support for both "Gemini 3" and "Gemini 3.1 Pro" selection identifiers for backward compatibility.
