FLUX 2 Add Background is optimized for English-language prompts starting with 'Add Background'. While the underlying AI may interpret some non-English terms, results quality and accuracy are not guaranteed for other languages. For best results, use clear English descriptors even if your final audience is international—visual concepts like 'tropical beach' or 'industrial warehouse' translate universally in the generated image. If you need multilingual prompt support for global teams, explore models like
Qwen Image 2 Edit which offer broader language understanding. Always test with English prompts first to establish baseline quality before experimenting with other languages.
