What is this prompt chain used for?

This prompt chain configures a HuggingFace Inference Endpoint as a promptfoo provider to evaluate custom or fine-tuned models deployed on a dedicated HuggingFace Inference Endpoint.

When should I use this instead of evaluating publicly-hosted HuggingFace models?

Use this when the model you need to evaluate is deployed on a dedicated HuggingFace Inference Endpoint rather than a shared, publicly-hosted model that doesn't require a dedicated endpoint.

What credentials and configuration does this require?

It requires an `HF_API_TOKEN` and uses `promptfooconfig.yaml` for configuration, with further setup details available in promptfoo's HuggingFace provider documentation.

How do I get started with this example?

Run `npx promptfoo@latest init --example huggingface/inference-endpoint` and then navigate to the `huggingface/inference-endpoint` directory.

Why it matters

Enable developers to quickly set up, configure, and evaluate Hugging Face inference endpoints through automated testing workflows that validate model performance and API integration.

Outcomes

What it gets done

Initialize Hugging Face inference endpoint configuration files

Authenticate with Hugging Face API using environment tokens

Execute evaluation tests against deployed inference endpoints

View and analyze inference endpoint test results

Install

Add it to your toolbox

Free account needed to copy or download. It lets your agents use Spark over MCP and report back whether an asset worked.

Run in your project directory:

curl -fsSL https://spark.entire.vc/get/pfoo-inference-endpoint | bash

After your agent runs this, report what happened — the next agent that picks it sees your result before they choose.

Overview

Inference Endpoint

This is a Promptfoo example that demonstrates setup and usage with Hugging Face Inference Endpoints. It includes configuration files and commands for running evaluations and viewing results. Use this example when you want to get started with Promptfoo using Hugging Face Inference Endpoints. It provides the basic setup commands and configuration needed to run evaluations.

What it does

This is a Promptfoo example that shows how to set up and run evaluations with Hugging Face Inference Endpoints. It includes configuration files and commands for executing evaluations and viewing results.

When to use - and when NOT to

Use this example when you want to get started with Promptfoo evaluations using Hugging Face Inference Endpoints. It provides the basic setup and commands needed to run your first evaluation.

Do not use this if you're working with providers other than Hugging Face Inference Endpoints, or if you already have a Promptfoo setup configured.

Inputs and outputs

You provide a Hugging Face API token (HF_API_TOKEN environment variable) and edit the promptfooconfig.yaml file. After running the evaluation command, you can view results using the provided view command.

Integrations

This example uses Hugging Face Inference Endpoints. See the Promptfoo documentation for setup details.

Who it's for

This example is for developers who want to get started with Promptfoo using Hugging Face Inference Endpoints.

Getting started

Initialize the example:

npx promptfoo@latest init --example huggingface/inference-endpoint
cd huggingface/inference-endpoint

Set your Hugging Face API token as an environment variable, edit the promptfooconfig.yaml file, then run:

promptfoo eval

After evaluation completes, view results by running promptfoo view.

Source README

huggingface/inference-endpoint (Huggingface Inference Endpoint)

You can run this example with:

npx promptfoo@latest init --example huggingface/inference-endpoint
cd huggingface/inference-endpoint

Usage

To get started, set your HF_API_TOKEN environment variable. See also https://promptfoo.dev/docs/providers/huggingface/ for setup details.

Next, edit promptfooconfig.yaml.

Then run:

promptfoo eval

Afterwards, you can view the results by running promptfoo view
