Inference types

This page lists the types (e.g. dataclasses) available for each task supported on the Hugging Face Hub. Each task is specified using a JSON schema, and the types are generated from these schemas - with some customization due to Python requirements. Visit @huggingface.js/tasks to find the JSON schemas for each task.

This part of the lib is still under development and will be improved in future releases.
