# Hugging Face Spaces Tool Template for Agents

- a quick tribute to [Aymeric](https://huggingface.co/m-ric) for this simple but effective exapmle of how to build and serve agents using Hugging Face spaces
- the one thing I've noticed with some of the reusable tools created by the HF team is that they appear to still use a number of potentially older transformer libraries
- just be aware that there are differences between the [smolagents](https://huggingface.co/docs/smolagents/main/en/reference/tools#smolagents.launch_gradio_demo) and [transformers](https://huggingface.co/docs/transformers/v4.48.0/en/main_classes/agent#transformers.launch_gradio_demo) implementations for some of these methods and you'll be fine

## [m-ric/text-to-image repo](https://huggingface.co/spaces/m-ric/text-to-image)

- the structure and content below is a full extract of the entire repo
- helps to understand the config and code required to publish and launch a reusable tool
- refer to the comment under `app.py` for an example of where the older transformers import is still used
