[Limitations and Notes]

1. Images generated by the free plan carry a watermark; watermark-free export requires a paid plan.
2. Issues such as the specific handling after credits are exhausted, supported file formats, and user ownership of generated images are listed as headings in the page's FAQ, but the provided materials do not give specific answers, so no clear explanation is currently available.
3. Regarding commercial use, the page lists a "Commercial Use License/Commercial License" item, but the specific terms and details are not currently provided.
4. Regarding data security, the page states that relevant certifications have been obtained, but the specific implementation details are not currently provided.
5. There is an inconsistency in version naming on the page: the title is Seedream 4.0 AI, while the body text refers to Seedream 5.0 in multiple places; the actual correspondence between the version and features should be based on the official website.
