Hugging Face

Models, datasets, Spaces, and inference infrastructure.

Agents can search model metadata, call inference endpoints, upload artifacts, and manage repos through API or CLI.

Limitations

Key limitations: Open model licenses, gated models, and hardware costs need review. Model behavior, costs, rate limits, data retention, and safety policies can change by model and account tier; use evals, spend caps, and data controls for sensitive workloads. CLI access is powerful but can run destructive local or production commands; prefer dry runs, preview environments, and non-production credentials. API automation needs client-side throttling, idempotency where supported, pagination limits, retries, and audit logging.
