# google-vertex (Google Vertex AI Examples)
|
|
|
|
Example configurations for testing Google Vertex AI models with promptfoo.
|
|
|
|
You can run this example with:
|
|
|
|
```bash
|
|
npx promptfoo@latest init --example google-vertex
|
|
cd google-vertex
|
|
```
|
|
|
|
## Purpose
|
|
|
|
- Test Vertex AI's Gemini, Claude, and Llama models
|
|
- Configure model-specific features and search grounding
|
|
- Compare performance across different tasks
|
|
|
|
## Prerequisites
|
|
|
|
- Google Cloud account with Vertex AI API enabled
|
|
- API credentials
|
|
- Node.js ^20.20.0 or >=22.22.0 (Node.js 20 support ends July 30, 2026; Node.js 24 LTS recommended)
|
|
|
|
## Environment Variables
|
|
|
|
- `VERTEX_PROJECT_ID` - Your Google Cloud project ID
|
|
- `GOOGLE_APPLICATION_CREDENTIALS` - Path to service account credentials (optional)
|
|
|
|
## Setup
|
|
|
|
1. Install dependencies:
|
|
|
|
```sh
|
|
npm install google-auth-library
|
|
```
|
|
|
|
2. Configure authentication:
|
|
|
|
```sh
|
|
# User account (development)
|
|
gcloud auth application-default login
|
|
|
|
# Or service account
|
|
export GOOGLE_APPLICATION_CREDENTIALS=/path/to/credentials.json
|
|
```
|
|
|
|
3. Set your project ID:
|
|
```sh
|
|
export VERTEX_PROJECT_ID=your-project-id
|
|
```
|
|
|
|
## Configurations
|
|
|
|
This example includes:
|
|
|
|
- `promptfooconfig.gemini.yaml`: Gemini models with function calling, system instructions, and safety settings
|
|
- `promptfooconfig.claude.yaml`: Claude models for technical writing and code analysis
|
|
- `promptfooconfig.llama.yaml`: Llama models with safety features and region configuration
|
|
- `promptfooconfig.search.yaml`: Search grounding for real-time information
|
|
- `promptfooconfig.response-schema.yaml`: Response schemas with structured output
|
|
|
|
## Running Examples
|
|
|
|
```sh
|
|
# Basic example
|
|
promptfoo eval -c promptfooconfig.yaml
|
|
|
|
# Model-specific examples
|
|
promptfoo eval -c promptfooconfig.gemini.yaml
|
|
promptfoo eval -c promptfooconfig.claude.yaml
|
|
promptfoo eval -c promptfooconfig.llama.yaml
|
|
|
|
# Search grounding tool and image understanding
|
|
promptfoo eval -c promptfooconfig.search.yaml
|
|
promptfoo eval -c promptfooconfig.image.yaml
|
|
|
|
# Structured output with response schemas
|
|
promptfoo eval -c promptfooconfig.response-schema.yaml
|
|
|
|
# View results
|
|
promptfoo view
|
|
```
|
|
|
|
## Expected Results
|
|
|
|
Each configuration demonstrates different model capabilities, from function calling and tool use to safety features and real-time information retrieval.
