Frequently Asked Questions

Everything you need to know about GPT Image 1.5

What is GPT Image 1.5 and how does it work?

GPT Image 1.5 is an AI image generation service that supports model, prompt, and other parameters. Send a text description and receive high-quality generated images — no complex configuration needed. You can also pass reference images (image_urls) to edit or blend pictures, and a mask (mask_url) to repaint only part of an image.

What parameters does GPT Image 1.5 support?

GPT Image 1.5 uses a minimal interface: model (e.g., gpt-image-1.5-official), prompt (your text description), and other optional parameters. This flexibility makes integration fast and reduces the learning curve for developers.

How do I write effective prompts for GPT Image 1.5?

Be specific about visual details (colors, lighting, composition), specify artistic style, and describe the scene clearly. The more descriptive your prompt, the better the generated image will match your vision.
