Issue: The API implementation is missing a newline at the end of the file.
Fix: Add a newline at the end of the file to follow best practices.
Impact: Improves code consistency and prevents potential issues with some tools that expect files to end with a newline.

💡 Optional Recommendation
Issue: Error handling for API failures is not explicitly implemented.
Fix: Consider adding error handling for API failures.
Impact: Improves robustness of the application by properly handling API errors.

💡 Optional Recommendation
Issue: The default model is hardcoded without any documentation about available models.
Fix: Add a comment explaining the default model choice and possibly other available models.
Impact: Improves code documentation and helps users understand model options.
