This release focuses on correcting the integration of the Z-Image (Lumina-Image-2.0) architecture, resolving geometric distortions and ensuring distinct behavior for all scaling methods. It also includes stability fixes.
Key Changes
Z-Image / Lumina-Image-2.0 Support
- Fixed Aspect Ratio Distortion: Implemented forced isotropic coordinate scaling to prevent the "vertical stretching" effect observed in non-square resolutions (e.g., portrait/landscape).
- Restored Method Differentiation: Resolved an issue where
vision_yarn,yarn, andntkproduced identical outputs. . - Coordinate Blending: Introduced a dynamic schedule that transitions from Position Interpolation (compressed coordinates) to Extrapolation (integer coordinates) over the diffusion process to improve structural stability.
- Artifact Mitigation: Adjusted Dynamic MScale parameters to reduce high-frequency speckle noise specific to Z-Image's low-theta architecture.
General & Flux
- Architecture Isolation: Enforced strict separation between model-specific logic (Z-Image vs. Flux/Qwen) to allow architecture-specific optimizations without causing regressions in other models.
