Frequently asked questions

How do AI agents use Hugging Face?+

Through the Inference API. Agents send inputs to specific model endpoints and receive structured outputs. This works for text generation, classification, embeddings, image processing, and more.

Which Hugging Face models work best with agents?+

Models with clear input/output schemas work best. Popular choices: sentence-transformers for embeddings, BART for summarization, Whisper for audio. Check the model card for API compatibility.

Free tier vs paid for AI agents?+

The free Inference API has rate limits and shared infrastructure. For production agents, use dedicated Inference Endpoints for guaranteed availability and higher throughput.
