While the AI-powered alt text generator provides useful descriptions, there are some known issues:
- Quality of Alt Tags: The generated alt tags are generally good, but in some cases, they may not be perfectly accurate or descriptive, particularly for complex images.
- Language Support: Although the model supports multiple languages, the quality of alt tags in languages other than English may be lower, and some languages may produce less accurate results.
One potential enhancement to improve the quality of the generated alt tags is to integrate a second AI model to validate the alt text before returning it. This secondary model could cross-check the description for accuracy, clarity, and language appropriateness, ensuring better results across all supported languages.
