Adversarial Gradient Forcing
Robust Few-Step Autoregressive Video Generation
Zhejiang University · Alibaba Group · Nanjing University
**AGF** improves long-video generation by training models to withstand **adversarial perturbations in their generated history**. Trained on five-second rollouts, it supports generation up to four minutes with the same four-step sampler.

## 🧩 Model details
AGF selects adversarial history perturbations using distribution-matching gradients from later video blocks, then trains jointly on clean and perturbed histories. A first-step prediction consistency regularizer helps preserve scene structure during the initial training stage.
| Property | Paper checkpoint |
| --- | --- |
| Architecture | Wan2.1 1.3B autoregressive video generator |
| Initialization | Self-Forcing ODE initialization |
| Training | 200 regularized AGF + 200 pure AGF outer iterations |
| Selected weights | Global step 400, `generator_ema` |
| Training rollouts | 5 seconds; effective batch size 64 |
| Training prompts | Filtered, LLM-extended VidProM prompts used by Self-Forcing |
| Inference | 832 × 480, 16 fps, four denoising steps per block |
Iterations count outer training loops; the full schedule contains **80 generator updates**.
## 🚀 Download and inference
The paper checkpoint is available as [`model.pt`](model.pt) (17.03 GB). Download it with the Hugging Face CLI:
```bash
hf download Wuli-art/Adversarial-Gradient-Forcing model.pt \
--local-dir checkpoints/AGF
```
Follow the [installation and inference guide](https://github.com/wuli-art/Adversarial-Gradient-Forcing/blob/main/docs/inference.md) for the Python/CUDA environment and Wan 1.3B assets. Place the downloaded checkpoint at `checkpoints/AGF/model.pt` and run from the code repository root:
```bash
AGF_RUN_ID=preview bash scripts/infer.sh \
--checkpoint checkpoints/AGF/model.pt \
--prompts prompts/examples.txt --latent-frames 21 --gpus 0
```
The script selects **`generator_ema` by default**, matching the paper. Use `--latent-frames 21`, `240`, or `960` for approximately **5 seconds**, **1 minute**, or **4 minutes**. The default policy uses 12 latent frames of local attention, including 3 persistent sink frames, with relative sink positions enabled. See the [training guide](https://github.com/wuli-art/Adversarial-Gradient-Forcing/blob/main/docs/training.md) for the full training and checkpoint-resumption workflow.
## 📊 Results
Paper results under the shared evaluation protocol (higher is better). The 5-second and 60-second evaluations use 944 and 240 VBench prompts, respectively; the 240-second evaluation uses 120 MovieGenVideoBench extended prompts.
| Model | 5 s · VBench Total | 60 s · VBench Total | 240 s · Quality 5 |
| --- | ---: | ---: | ---: |
| **AGF** | **82.03** | **81.47** | **84.82** |
Quality 5 (Q5) is the arithmetic mean of subject consistency, background consistency, motion smoothness, aesthetic quality, and imaging quality. It excludes dynamic degree and is not an official VBench Total score. See the [evaluation protocol](https://github.com/wuli-art/Adversarial-Gradient-Forcing/blob/main/docs/evaluation.md) for metric definitions and reproducibility details.
## Intended use and limitations
AGF is intended for text-to-video generation and research on autoregressive video models. Long sequences may exhibit visual artifacts, motion inconsistencies, or prompt drift.
