How this comparison is made
The tables above come from published specs and hands-on use. They contain no scores we have not measured. A shared eight-category benchmark — portrait, product, poster text, anime character, interior, multi-reference, image editing and character consistency — is running for every model, and real generation time, success rate and text accuracy figures will be added here when it completes. Until then, the most reliable test is running your own prompt side by side above.
