| Free tier | a free account in good standing (verified email, older than 30 days) may host up to 2 ZeroGPU Spaces and use 5 minutes of GPU a day, on a half RTX Pro 6000 Blackwell with 48 GB VRAM unit minutes; metered on wall-clock; The quota is per day and resets 24 hours after first use. Only the Gradio SDK is compatible. |
|---|
| Price | none stated |
|---|
| Limits | - volume-quota (binding) 5 minutes of GPU a day on a free account source
- write-gated verified email and an account older than 30 days source
|
|---|
| Binding | volume-quota 5 minutes a day is 300 seconds, and a single diffusion call can eat a tenth of it |
|---|
| Identity | email a verified email and an account older than 30 days; no card. The 30-day age is the real gate and cannot be bought past. |
|---|
| Egress | no egress allowance published |
|---|
| Per-object cap | not applicable: the unit is a session, not an object |
|---|
| Retention | the Space repo persists; the GPU allocation is per function call and released on completion |
|---|
| Interface | rest one https endpoint per Space serving a Gradio app; no SSH and no shell |
|---|
| Tooling | Gradio on the Space SDK; huggingface_hub |
|---|
| Composes with | 5 minutes of GPU a day for a Gradio demo, which is an inference budget and not a training budget |
|---|
| Reliability | quota exhaustion drops the caller down the GPU queue, and the xlarge size costs double quota for the same wall-clock |
|---|
| Notes | The best VRAM for free and the smallest time budget. It is a serving allowance for a public demo, not a compute allowance for a job. |
|---|
| Evidence note | documented the daily quotas, the account gate and the VRAM are quoted from the ZeroGPU docs today. |
|---|
| Parsed numbers | - price USD 0 / month
- price USD 0 / month
- volume-quota 5 minutes
