Everything you need to know about GPT Image 1.5
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.
GPT Image 1.5 uses a minimal interface: model (e.g., gpt-image-1.5), prompt (your text description), and other optional parameters. This flexibility makes integration fast and reduces the learning curve for developers.
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.
Use your APIMart access key to authenticate, then send a POST request with model, prompt, and other parameters in the request body. Check our documentation for sample code and full reference.
Pay-as-you-go pricing with no hidden fees or monthly minimums. Your balance can be used across all models on the platform. Check the pricing page for current rates.
