integration-vercel/ai-gateway (Vercel AI Gateway Example)

This example demonstrates how to use Vercel AI Gateway to access multiple AI providers through a unified API.

Prerequisites

Set the required environment variable:

bash

export VERCEL_AI_GATEWAY_API_KEY=your_api_key

bash

npx promptfoo@latest init --example integration-vercel/ai-gateway
npx promptfoo eval

Or run directly:

bash

npx promptfoo eval -c examples/integration-vercel/ai-gateway/promptfooconfig.yaml

The configuration compares responses from three different providers, all accessed through Vercel AI Gateway:

Each provider answers questions about technical topics, and the assertions verify that responses contain relevant keywords.
