Short answerHugging Face says static Spaces are free and CPU Basic hardware (2 vCPU, 16 GB) has no hourly cost, but Gradio and Docker Spaces require a paid plan to create. Free Spaces sleep when unused. HuggingChat Assistants appear to be closed.
- Default hardware: 16 GB RAM, 2 CPU cores, 50 GB non-persistent disk.
- Static Spaces are free; Gradio and Docker Spaces run on compute and, per the docs, require a paid plan such as PRO to create (with some free ZeroGPU exceptions).
- Free hardware goes to sleep after a period of unuse.
- Outbound traffic is limited to ports 80, 443 and 8080.
- Inference Providers: pay-as-you-go with no markup; free users get no monthly credits and PRO users get $2.00 per month.
