Gpt-image-1 Size Missing In ImageEditParams

by ADMIN 44 views

Introduction

The OpenAI API provides a powerful tool for generating images using the gpt-image-1 model. However, when using the ImageEditParams class in the Node library, the size property is missing for the gpt-image-1 model. This issue is specific to the Node library and not an underlying OpenAI API issue.

Describe the Bug

The size property in the ImageEditParams class is defined as follows:

/**
   * The size of the generated images. Must be one of `1024x1024`, `1536x1024`
   * (landscape), `1024x1536` (portrait), or `auto` (default value) for
   * `gpt-image-1`, and one of `256x256`, `512x512`, or `1024x1024` for `dall-e-2`.
   */
  size?: '256x256' | '512x512' | '1024x1024' | null;

However, this definition is incomplete for the gpt-image-1 model. The correct definition should include the additional sizes 1536x1024 (landscape) and 1024x1536 (portrait). The corrected definition is:

/**
   * The size of the generated images. Must be one of `1024x1024`, `1536x1024`
   * (landscape), `1024x1536` (portrait), or `auto` (default value) for
   * `gpt-image-1`, and one of `256x256`, `512x512`, or `1024x1024` for `dall-e-2`.
   */
  size?: '256x256' | '512x512' | '1024x1024' | '1536x1024' | '1024x1536' | 'auto' | null;

To Reproduce

To reproduce this issue, follow these steps:

  1. Install the latest version of the Node library (v4.96.0)
  2. Import the ImageEditParams class with the gpt-image-1 model

Code Snippets

// Import the ImageEditParams class
const { ImageEditParams } = require('openai');

// Create an instance of ImageEditParams with the gpt-image-1 model
const params = new ImageEditParams({
  model: 'gpt-image-1',
});

// Attempt to set the size property
params.size = '1024x1024'; // This should work
params.size = '1536x1024'; // This should work
params.size = '1024x1536'; // This should work
params.size = 'auto'; // This should work

// However, attempting to set the size to any other value will result in an error
params.size = '256x256'; // This should throw an error
params.size = '512x512'; // This should throw an error

OS and Node Version

This issue was reproduced on:

  • macOS
  • Node version: v20.15.0
  • Library version: 4.96.0

Conclusion

In conclusion, the size property in the ImageEditParams class is missing for the gpt-image-1 model. This issue is specific to the Node library and not an underlying OpenAI API issue. To reproduce this issue, install the latest version of the Node library and import the ImageEditParams class with the gpt-image-1 model. The corrected definition for the size property is:

/**
   * The size of the generated images. Must be one of `1024x1024`, `1536x1024`
   * (landscape), `1024x1536` (portrait), or `auto` (default value) for
   * `gpt-image-1`, and one of `256x256`, `512x512`, or `1024x1024` for `dall-e-2`.
   */
  size?: '256x256' | '512x512' | '1024x1024' | '1536x1024' | '1024x1536' | 'auto' | null;
