OMNIALPHA: Aligning Transparency-Aware Generation via Multi-Task Unified Reinforcement Learning
Revolutionizing RGBA Generation with Unified RL
OMNIALPHA introduces a novel unified multi-task reinforcement learning framework for transparency-aware generation and manipulation. It addresses the fragmentation in RGBA-related methods by combining an alpha-aware VAE with a sequence-to-sequence Diffusion Transformer, enhanced with a bi-directional layer coordinate for processing multiple RGBA inputs and outputs. The model leverages GRPO-style post-training with layer-aware rewards, explicitly optimizing cross-layer coherence and fine transparency details, which SFT alone struggles to capture. Experiments demonstrate OMNIALPHA's superior performance across five transparency-aware tasks, outperforming both its SFT baseline and specialized expert models, including significant improvements in RGB L1 for layer decomposition and SAD/Grad for automatic matting.

Unified RGBA Generation
OMNIALPHA introduces a single, unified model for generating and manipulating RGBA images, moving beyond fragmented task-specific solutions. This foundational model integrates an alpha-aware VAE with a Diffusion Transformer to handle RGB appearance, alpha-based opacity, and cross-layer composition for diverse visual creation workflows.
Reinforcement Learning Alignment
The core innovation of OMNIALPHA is its GRPO-style post-training with layer-aware rewards. This reinforcement learning approach directly optimizes for critical properties like cross-layer consistency and alpha-boundary precision, which supervised fine-tuning alone cannot fully achieve, leading to significant performance gains.
Multi-Task Capabilities
OMNIALPHA demonstrates versatility across five transparency-aware tasks: text-to-image generation, object removal, automatic matting, referring matting, and layer decomposition. This unified approach consolidates separate pipelines into a single, highly generalizable policy, delivering state-of-the-art performance across these diverse applications.
