## Analogy

npm for models. OpenAI is a paid SaaS API; Hugging Face is where you pick a package and run it yourself.

## In an agent

Use it when a small, free or private model does a job better than paying an LLM API for every call.

## Questions people ask

### What is the Hugging Face Hub?

The Hugging Face Hub is a public site with hundreds of thousands of open models and datasets, plus libraries to run them. Think of it as npm for models: you pick a model and run it yourself, instead of paying a provider like OpenAI for every call to their API.

### When should I use a Hugging Face model instead of OpenAI?

When a small, focused model can do the job: embeddings, classification or sentiment at high volume, or work on private data that must not leave your servers. For open-ended reasoning and tool calling, a large hosted model like OpenAI or Claude is usually still the better choice.
