## When it is useful

Write or review @spaces.GPU ZeroGPU code: pickle isolation, duration/quota, no torch.compile. Gradio ZeroGPU only — Docker, Static, and Streamlit-as-Docker will not schedule. Distinct from huggingface-spaces hosting and from huggingface-gradio UI.

## The Catch

@spaces.GPU / pickle isolation. Gradio ZeroGPU only — Docker/Static/Streamlit-as-Docker will not schedule. Distinct from huggingface-spaces. Free still max 2 ZeroGPU Spaces.
