+# Action Chunking Transformer
+
+That's a basic model for solving simplest imitation learning tasks.
+The original implementations can be found [here](https://github.com/tonyzhaozh/act/tree/main).
+
+The model takes images from one or multiple cameras and robot state and produces
+a chunk of actions, which robot can execute as a sequence of movements in real world.
+
+The model weights are random and provided only for testing purposes.
+
+# How to Use
+
+## Installation
+
+```bash
+uv pip install physicalai-train
+```
+
+## Running Inference
+
+The following API example showcases inference API for this model:
+
+```python
+import numpy as np
+from physicalai.inference import InferenceModel
+
+model = InferenceModel("act_ov_fp16", device="CPU")
+
+# Build a dummy LIBERO-style observation.
+# LIBERO provides two cameras (agentview + wrist) and an 8-dim robot state.
+# Images use the LeRobot convention: float32 in [0, 1], shape (C, H, W).
+observation = {
+    "images.image": np.random.rand(3, 256, 256).astype(np.float32),
+    "images.image2": np.random.rand(3, 256, 256).astype(np.float32),
+    "state": np.zeros(8, dtype=np.float32),
+}
+
+chunk = model.predict_action_chunk(observation)
+```
+
+Note, that the model should be downloaded and saved to `act_ov_fp16` folder prior to running this script.
