First of all, I am an inexperienced user. The reason I purchased a Pro account was to increase the zero GPU limit in spaces. However, I keep getting errors so often when I work in spaces and I see that my credits are running out while I’m trying. Why does this deduct from my GPU usage credits when I encounter an error? How can I fix this? I use Text to Image and Image to 3D spaces. Hunyuan 3D 2.1.

Because [ZeroGPU bills for **GPU allocation time** , not success](https://huggingface.co/docs/hub/en/spaces-zerogpu).
Since it’s a service where multiple users share the GPU, resources get locked up during the reservation phase. To work efficiently in error-prone Spaces, you sometimes need to duplicate it for your own use and modify it to avoid errors.
[Reporting errors to the author via the Community tab is the proper method](https://huggingface.co/spaces/tencent/Hunyuan3D-2.1/discussions), but fixes often take time…

Thank you for the explanation.
