LongCat Image Test Results

Testing in progress

Every model runs the same eight-category prompt set — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — recording generation time, success rate, text accuracy and identity retention. That run has not finished for LongCat Image, so this page shows no scores. We do not publish numbers we have not measured.

LongCat Image Limitations

Text-to-image only on this endpoint
