| Feature | Differentiable RL | TDM-R1 |
|---|---|---|
| Reward Type | Differentiable only | Non-differentiable & Differentiable |
| Reward Signal Use | Backpropagation through reward | Decoupled Surrogate Reward Learning |
| Intermediate Reward | Endpoint only (biased) | Accurate per-step (deterministic path) |
| Blurry Outputs (few-step) | Prone to blurry outputs | Preserves high visual quality |
| Generality | Narrower application | Broader applicability (human pref, object counts) |
Case Study: Z-Image Model Enhancement
Scenario: Applied TDM-R1 to the 6B-parameter Z-Image model.
Results: Consistently outperformed both its 100-NFE and few-step variants with only 4 NFEs across in-domain and out-of-domain metrics. This demonstrates TDM-R1's scalability and efficiency in enhancing powerful foundational models.
Key Benefit: Increased performance with significantly reduced inference costs.
