Definition
Hugging Face Spaces is a hosting platform for sharing and running interactive machine learning demo applications directly in the browser, using frameworks like Gradio or Streamlit, backed by Hugging Face's model and dataset ecosystem.
Overview
Hugging Face Spaces lets developers publish a working AI demo — a chatbot, image generator, or model comparison tool — as a live web app, without managing their own servers. A Space is essentially a small Git repository that Hugging Face automatically builds and runs, most commonly using Gradio or Streamlit for the UI layer, though Docker-based Spaces allow essentially any web application. Spaces are tightly integrated with the rest of the Hugging Face ecosystem: a demo can pull a model directly from the Hugging Face Hub, reference a dataset, and be embedded elsewhere via an iframe. This makes Spaces the de facto place the open-source ML community shares reproducible demos of new models, papers, and techniques — when a new open-weight diffusion model or LLM is released, a Space showcasing it typically appears within days. Free Spaces run on shared CPU or basic GPU hardware with usage limits, while paid tiers offer dedicated, more powerful GPUs for demos that need faster inference or handle more traffic. This tiered model mirrors platforms like Civitai in the image-generation community, where free community hosting coexists with paid compute for heavier workloads. Because Spaces are so easy to fork and modify, they also serve an educational purpose: a student can duplicate an existing Space, tweak the code, and immediately see the effect, making it a popular hands-on complement to courses like Hugging Face Transformers.

Hugging Face Transformers is a Python library that gives you pretrained NLP models in a few lines of code, no training from scratch required.
Read More AI & TechnologyThe Hugging Face Stack: Hub, Transformers, Datasets and PEFT
The Hugging Face stack is five or six libraries that each own one stage of a model's life: the Hub stores artefacts, Transformers loads and runs them, Datasets feeds them, PEFT adapts them cheaply, Accelerate distributes the training loop, and Spaces exposes the result. This guide maps each boundary so you know which tool to reach for.
