# OpenRouter Async Models Error - FIXED ## Issue Summary **Date**: 2025-06-10 **Error**: TypeError when selecting OpenRouter provider in FreeCAD AI addon ## Problem Details ``` RuntimeWarning: coroutine 'OpenRouterProvider.get_available_models' was never awaited TypeError: 'PySide2.QtWidgets.QComboBox.addItems' called with wrong argument types: PySide2.QtWidgets.QComboBox.addItems(coroutine) ``` **Root Cause**: OpenRouter provider's `get_available_models()` method was async, but the UI widget expected a synchronous call returning a list of strings. ## Fix Implemented ### 1. Made `get_available_models()` Synchronous ✅ **File**: `/freecad-ai/ai/providers/openrouter_provider.py` **Before (Problematic)**: ```python async def get_available_models(self) -> List[Dict[str, Any]]: # Async API call that returned coroutine ``` **After (Fixed)**: ```python def get_available_models(self) -> List[str]: """Get list of available models for UI compatibility.""" return self.OPENROUTER_MODELS.copy() ``` ### 2. Added Async Version for Advanced Use ✅ ```python async def get_available_models_async(self) -> List[Dict[str, Any]]: """Get list of currently available models from OpenRouter API.""" # Dynamic API fetching when needed ``` ## Impact - **Immediate**: OpenRouter provider selection no longer crashes the UI - **Model Dropdown**: Now populates correctly with available models - **Compatibility**: Matches pattern used by other providers (anthropic, google, openai) - **No Regression**: Other providers continue to work normally - **Future-Proof**: Async method available for when dynamic model fetching is needed ## Testing The fix addresses the core async/sync mismatch that was preventing users from selecting OpenRouter as their AI provider. Users should now be able to: 1. Select OpenRouter from the provider dropdown 2. See available models populate in the model dropdown 3. Configure OpenRouter settings without UI crashes 4. Use OpenRouter for AI conversations ## Files Modified - `freecad-ai/ai/providers/openrouter_provider.py` - Fixed async/sync interface ## Task Status - **BUGFIX_004**: Completed ✅ - **Related Tasks**: This builds on the provider service import fix from BUGFIX_003 This completes the provider-related fixes needed for stable OpenRouter operation in the FreeCAD AI addon.
