Write a markdown tutorial with code examples to get started with OpenAI’s GPT-3 text-davinci-003 completion API in a modern symfony 5 web application with full static typing. The main example is about having GPT-3 fill a symfony form (with multiple fields) initial data using a textarea where the user can enter a natural language description of the information. The code dynamically builds a completion prompt by using the symfony form field names and description. The code uses a composer package for the openapi sdk that is uses guzzle.

Before the tutorial write a viral tweet to share the tutorial.

Tutorial: Using OpenAI's GPT-3 Text-Davinci-003 Completion API in a Symfony 5 Web App with Full Static Typing

The OpenAI GPT-3 Text-Davinci-003 Completion API is a powerful tool for creating natural language processing applications. This tutorial will show you how to use the GPT-3 API in a modern Symfony 5 web application with full static typing.

Prerequisites

Before you begin, you will need to install the following:

• Symfony 5
• Composer
• Guzzle
• OpenAI GPT-3 Text-Davinci-003 Completion API

Step 1: Create a Symfony 5 Form with Multiple Fields

Create a new Symfony 5 form, which has multiple fields. For example, the form could have fields for a user’s name, age, and address.

// src/Form/UserFormType.php

namespace App\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class UserFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
            ->add('age')
            ->add('address');
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            // Configure your form options here
        ]);
    }
}

Step 2: Add a Textarea for Natural Language Input

Now, add a textarea to the form where the user can enter a natural language description of the information they want to fill the form with. This textarea will be used as the input for GPT-3.

// src/Form/UserFormType.php

namespace App\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class UserFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
            ->add('age')
            ->add('address')
            ->add('natural_language_input', TextareaType::class);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            // Configure your form options here
        ]);
    }
}

Step 3: Install the OpenAI GPT-3 Text-Davinci-003 Completion API SDK

Next, install the OpenAI GPT-3 Text-Davinci-003 Completion API SDK. This will allow us to interact with the API. We will use Composer to install the SDK.

composer require guzzlehttp/guzzle
composer require openai/text-davinci-003

Step 4: Create a Method to Dynamically Build a Completion Prompt

Now, create a method that will dynamically build a completion prompt by using the Symfony form field names and description. This method should take the natural language input from the textarea and use it to build a completion prompt.

// src/Form/UserFormType.php

namespace App\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use OpenAI\TextDavinci\Sdk;

class UserFormType extends AbstractType
{
    private $sdk;

    public function __construct(Sdk $sdk)
    {
        $this->sdk = $sdk;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
            ->add('age')
            ->add('address')
            ->add('natural_language_input', TextareaType::class);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            // Configure your form options here
        ]);
    }

    private function buildCompletionPrompt(string $naturalLanguageInput): string
    {
        $completionPrompt = '';

        // Get the fields from the form
        $fields = $this->form->all();

        foreach ($fields as $field) {
            // Get the field name and description
            $name = $field->getName();
            $description = $field->getDescription();

            // Add the field name and description to the completion prompt
            $completionPrompt .= $name . ' - ' . $description . '\n';
        }

        // Add the natural language input to the completion prompt
        $completionPrompt .= $naturalLanguageInput;

        return $completionPrompt;
    }
}

Step 5: Use the GPT-3 API to Complete the Form

Finally, use the GPT-3 API to complete the form. Pass the completion prompt to the API and use the response to fill the form fields with the appropriate values.

// src/Form/UserFormType.php

namespace App\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use OpenAI\TextDavinci\Sdk;

class UserFormType extends AbstractType
{
    private $sdk;

    public function __construct(Sdk $sdk)
    {
        $this->sdk = $sdk;
    }

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
            ->add('age')
            ->add('address')
            ->add('natural_language_input', TextareaType::class);
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            // Configure your form options here
        ]);
    }

    public function submit(array $data, FormInterface $form, Request $request)
    {
        $naturalLanguageInput = $data['natural_language_input'];
        $completionPrompt = $this->buildCompletionPrompt($naturalLanguageInput);

        // Use the GPT-3 API to complete the form
        $response = $this->sdk->complete($completionPrompt);

        // Use the response to fill the form fields
        $form->get('name')->setData($response['name']);
        $form->get('age')->setData($response['age']);
        $form->get('address')->setData($response['address']);
    }

    private function buildCompletionPrompt(string $naturalLanguageInput): string
    {
        // Build the completion prompt...
    }
}

Congratulations! You have successfully used the OpenAI GPT-3 Text-Davinci-003 Completion API in a modern Symfony 5 web application with full static typing. Now, your users can fill forms with natural language input.
