+## 📢 News
+
+* **2025-03:** Paper and Code of [FAR](https://farlongctx.github.io/) are released! 🎉
+
+
+## 🌟 What's the Potential of FAR?
+
+### 🔥 Introducing FAR: a new baseline for autoregressive video generation
+
+FAR (i.e., <u>**F**</u>rame <u>**A**</u>uto<u>**R**</u>egressive Model) learns to predict continuous frames based on an autoregressive context. Its objective aligns well with video modeling, similar to the next-token prediction in language modeling.
+
+![dmlab_sample](./assets/pipeline.png)
+
+### 🔥 FAR achieves better convergence than video diffusion models with the same continuous latent space
+
+<p align="center">
+<img src="./assets/converenge.jpg" width=55%>
+<p>
+
+### 🔥 FAR leverages clean visual context without additional image-to-video fine-tuning:
+
+Unconditional pretraining on UCF-101 achieves state-of-the-art results in both video generation (context frame = 0) and video prediction (context frame ≥ 1) within a single model.
+
+<p align="center">
+<img src="./assets/performance.png" width=75%>
+<p>
+
+### 🔥 FAR supports 16x longer temporal extrapolation at test time
+
+<p align="center">
+<img src="./assets/extrapolation.png" width=100%>
+<p>
+
+### 🔥 FAR supports efficient training on long-video sequence with managable token lengths

+
+## 🚀 Training
+
+To train different models, you can run the following command:
+
+```bash
+accelerate launch \
+    --num_processes 8 \
+    --num_machines 1 \
+    --main_process_port 19040 \
+    train.py \
+    -opt train_config.yml
+```
+
+* **Wandb:** Set ```use_wandb``` to ```True``` in config to enable wandb monitor.
+* **Periodally Evaluation:** Set ```val_freq``` to control the peroidly evaluation in training.
+* **Auto Resume:** Directly rerun the script, the model will find the lastest checkpoint to resume, the wandb log will automatically resume.
+* **Efficient Training on Pre-Extracted Latent:** Set ```use_latent``` to ```True```, and set the ```data_list``` to correponding latent path list.
+
+## 💻 Sampling & Evaluation
+
+To evaluate the performance of a pretrained model, just copy the training config and set the ```pretrain_network: ~``` to your trained folder. Then run the following scripts:
+
+
+```bash
+accelerate launch \
+    --num_processes 8 \
+    --num_machines 1 \
+    --main_process_port 10410 \
+    test.py \
+    -opt test_config.yml
