Model Routing
Passy’s intelligent routing automatically:- Chooses cost-effective models by default for optimal price-to-performance
- Scales to more powerful models based on your request’s complexity
- Handles large contexts intelligently by selecting models with appropriate context windows
- Falls back to alternatives if a model is unavailable
Troubleshooting
Authentication Errors
If you encounter authentication issues:- Verify your API key is correct and active
- Ensure the base URL is set to
https://api.passy.ai/v1 - Check your Passy account has sufficient credits in the dashboard
- Try removing and re-adding the API key in Cursor settings
Model Not Found
If you see “model not found” errors:- Verify the model ID exists in the models catalog
- Check you’re using the correct model name format
- Some provider-specific models may require additional configuration
- Try using a standard model name like
gpt-4oorclaude-3.5-sonnet
Slow Responses
If responses are slower than expected:- Check your internet connection speed
- Monitor your usage in the Passy dashboard
- Consider using faster models like
gpt-4o-minifor autocomplete - Reduce context size by limiting the number of files Cursor analyzes
