 We currently support two awesome Python SDKs (**[Gradio](https://gradio.app/)** and **[Streamlit](./spaces-sdks-streamlit)**) that let you build cool apps in a matter of minutes. Users can also create static Spaces, which are simple HTML/CSS/JavaScript pages, or deploy any Docker-based application.
 
+If you need GPU power for your demos, try [**ZeroGPU**](./spaces-zerogpu): it dynamically provides NVIDIA H200 GPUs, in real-time, only when needed.
+
 After you've explored a few Spaces (take a look at our [Space of the Week!](https://huggingface.co/spaces)), dive into the [**Spaces documentation**](./spaces-overview) to learn all about how you can create your own Space. You'll also be able to upgrade your Space to run on a GPU or other accelerated hardware. ⚡️
