The Photomaker API has been significantly optimized, resulting in a 45% increase in speed and nearly 50% reduction in serving costs compared to the previous version. This enhancement is achieved through the introduction of an "optimize" parameter that enables highly optimized mode for processing. Performance improvements have been extensively tested across various scenarios and step counts, with speed enhancements ranging from 26.06% to 44.77%. The new API offers faster responses and lower expenses for users while maintaining quality.
