Traditional Unified Multimodal Models (UMMs) suffer from a fundamental disconnect: visual understanding is optimized through sparse text signals, while generation relies on dense pixel objectives. This decoupled training creates misaligned representation spaces, hindering mutual reinforcement between perception and generation. Our core hypothesis is that generative post-training, using hierarchical visual tasks as proxies, can bridge this isolation.
Semantic Generative Tuning (SGT) is introduced as a novel paradigm leveraging image segmentation as a generative proxy. Unlike low-level reconstruction tasks that over-emphasize textures and distract models, segmentation provides structural semantics crucial for both vision-centric perception and generative layout fidelity. This approach aims to align and synergize multimodal capabilities.
Mechanistic analyses reveal that SGT fundamentally improves feature linear separability, enabling clearer class separation for semantically similar categories like 'Upright Piano' and 'Grand Piano'. Furthermore, SGT optimizes visual-textual attention allocation, increasing focus on critical tokens (Object, Color, Relation) and mitigating linguistic over-reliance, which helps counteract hallucination.
Extensive evaluations across mainstream UMM architectures like BAGEL and OmniGen2 demonstrate SGT's efficacy. It consistently improves both multimodal comprehension and generative fidelity. For instance, SGT-BAGEL achieves a 6.02% performance increase on CV-Bench and a 90.0% score on GenEval, outperforming baseline models and state-of-the-art competitors.

Unified Semantic-Structural Space (Synergy)
| Alignment Strategy Comparison | SGT | Pixel-Level |
|---|---|---|
| Primary Objective | Semantic-level alignment, structural essence | Pixel-perfect reconstruction, low-level textures |
| Impact on Understanding | Significantly enhances vision-centric perception and reasoning | Limited, often distracts with granular details |
| Impact on Generation | Improves generative layout fidelity and adherence to prompts | Yields measurable improvements but sub-optimal alignment |
| Representation Space | Restores representational unity, improves feature separability | Yields misaligned representation spaces, isolation |
SGT in Action: Enhanced Generative Fidelity
Figure 4 (from the paper) qualitatively demonstrates how SGT leads to superior adherence to complex textual prompts, including spatial and color instructions, compared to baseline models. For instance, generating 'a purple glass and a black apple' or 'a tie right of a baseball bat' shows marked improvement in object placement and color accuracy. This confirms SGT's synergetic benefit on overall UMM capabilities, indicating a deeper semantic understanding rather than just pixel-level matching.
