+# FastVLM: Efficient Vision Encoding for Vision Language Models
+
+FastVLM was introduced in
+**[FastVLM: Efficient Vision Encoding for Vision Language Models](https://www.arxiv.org/abs/2412.13303). (CVPR 2025)**
+
+[//]: # (![FastViTHD Performance](acc_vs_latency_qwen-2.png))
+<p align="center">
+<img src="acc_vs_latency_qwen-2.png" alt="Accuracy vs latency figure." width="400"/>
+</p>
+
+### Highlights
+* We introduce FastViTHD, a novel hybrid vision encoder designed to output fewer tokens and significantly reduce encoding time for high-resolution images.  
+* Our smallest variant outperforms LLaVA-OneVision-0.5B with 85x faster Time-to-First-Token (TTFT) and 3.4x smaller vision encoder.
+* Our larger variants using Qwen2-7B LLM outperform recent works like Cambrian-1-8B while using a single image encoder with a 7.9x faster TTFT.
+

+### Usage Example
+To run inference of PyTorch checkpoint, follow the instruction in the official repo:
+
+Download the model
+```
+huggingface-cli download apple/FastVLM-1.5B
+``` 
+
+Run inference using `predict.py` from the official repo.
+```bash
+python predict.py --model-path /path/to/checkpoint-dir \
+                  --image-file /path/to/image.png \
+                  --prompt "Describe the image."
+```
