What is the free ZeroGPU quota for 1 space?

Hugging Face's free ZeroGPU quota is 5 GPU-minutes per day per account, but a separate request-based limit of 3 runs per day for free users was confirmed by Hugging Face staff member hysts in an April 2026 forum thread. The official documentation lists only the time-based quota, so the run limit may still apply but is not currently documented.

Um, I’ve never personally hit a per-Space limit, but Free accounts do have another limit , so that might be what you’re seeing: The currently documented ZeroGPU quota for a Free account is 5 GPU-minutes per day . The current ZeroGPU documentation https://huggingface.co/docs/hub/spaces-zerogpu describes that as an account-tier daily quota , not as “5 minutes for each Space.” It also says the included quota resets exactly 24 hours after your first GPU usage. However, there is another limit which is easy to miss because it is not currently listed in that quota table. In this April 2026 Forum thread https://discuss.huggingface.co/t/free-account-zerogpu-quota-issue/175180 , hysts explained that Free users had a separate limit on how many times they could run ZeroGPU Spaces per day , in addition to the time-based quota. When someone asked whether both limits existed, the answer was yes; and the follow-up answer https://discuss.huggingface.co/t/free-account-zerogpu-quota-issue/175180/9 said that the request-based limit at that time was 3 runs per day . So the model was roughly: Free account ├─ time-based quota: 5 GPU-min/day └─ request/run-based limit: 3/day according to the April 2026 HF Forum answer That second limit could explain a situation where your quota meter still seems to have plenty of GPU time left, but you can no longer run a Space. One caveat: I would not treat 3/day as a permanently documented current value. The official ZeroGPU docs currently show the 5-minute time quota but do not show the request-count limit, and I could not find a newer public HF statement saying whether the April value has since changed or been removed. So the safest wording is: HF staff said it was 3/day in April; it may still be the limit, but the current docs do not expose that number. A simple way to distinguish the cases is: Still have GPU minutes left | +-- already made ~3 ZeroGPU runs today | - the separate Free request/run limit is a strong candidate | +-- only 1–2 runs, but this particular Space refuses - per-request duration / xlarge quota cost becomes more interesting Also, in the April thread, hysts noted that when the new run limit was introduced, reaching it could temporarily produce the same kind of quota error as exhausting GPU time. So the wording of a “quota exceeded” error by itself does not necessarily tell you which limit was reached. So, if by “one Space seems to be lower” you mean “I still have some of my 5 minutes left, but after roughly three uses it stops working,” I would first suspect the separate Free-account run limit rather than a special quota assigned to that individual Space. If instead that one Space fails after only one or two attempts while other ZeroGPU Spaces still work , then it is probably worth looking at that Space’s requested duration / GPU size or treating it as a Space-specific issue.
