​
What you can do

Prism Vertex supports text generation, structured output, and embeddings across multiple AI providers:

​
Text generation

Generate text with models from Google, Anthropic, Meta, Mistral, and more: 
use Prism\Prism\Prism;
use Prism\Vertex\Enums\Vertex;

$response = Prism::text()
    ->using(Vertex::Gemini, 'gemini-2.5-flash')
    ->withPrompt('Explain quantum computing in simple terms')
    ->asText();

echo $response->text;

​
Structured output

Get JSON responses that conform to your schema: 
use Prism\Prism\Prism;
use Prism\Vertex\Enums\Vertex;
use Prism\Prism\Schema\ObjectSchema;
use Prism\Prism\Schema\StringSchema;

$schema = new ObjectSchema(
    name: 'task',
    description: 'A programming task',
    properties: [
        new StringSchema('title', 'Task title'),
        new StringSchema('description', 'Task description'),
    ]
);

$response = Prism::structured()
    ->using(Vertex::Gemini, 'gemini-2.5-flash')
    ->withSchema($schema)
    ->withPrompt('Create a task for refactoring authentication')
    ->asStructured();

$data = $response->structured;

​
Embeddings

Generate vector embeddings for semantic search and similarity: 
use Prism\Prism\Prism;
use Prism\Vertex\Enums\Vertex;

$response = Prism::embeddings()
    ->using(Vertex::Gemini, 'text-embedding-005')
    ->fromInput('The sky is blue')
    ->asEmbeddings();

$embeddings = $response->embeddings;

​

Two modes of operation

Prism Vertex supports both Standard and Express modes:

​
Standard mode

Use your Google Cloud project with full control over location, authentication, and all available models: 
'vertex' => [
    'project_id'  => env('VERTEX_PROJECT_ID'),
    'location'    => env('VERTEX_LOCATION', 'us-central1'),
    'credentials' => env('VERTEX_CREDENTIALS'),
],

​
Express mode

Quick setup with just an API key for Google Gemini models: 
'vertex' => [
    'api_key' => env('VERTEX_API_KEY'),
],
Express mode only supports Google Gemini models. Partner models require Standard mode with project_id and location.

​
Requirements

  • PHP 8.2 or higher
  • Laravel 11 or 12
  • Prism PHP 0.99.16 or higher
