gpt-image / 1.5-text-to-image

GPT Image 1.5 is OpenAI’s flagship image generation model for high-quality image creation and precise image editing, with strong instruction following and improved text rendering.

Model Type:
Pricing: text-to-image or image-to-image: medium quality 4 credits ($0.02) per image, high quality 22 credits ($0.11) per image — ~35–45% cheaper than fal pricing. High-tier top-ups (+10% bonus) bring effective pricing down to ~$0.018 per image (medium quality) and ~$0.10 per image (high quality).
Input

A text description of the image you want to generate

0/3000

Width-height ratio of the image, determining its visual form.

Quality: medium=balanced, high=slow/detailed.

GPT Image 1.5 is OpenAI’s latest flagship image generation model, built for high-quality image creation and precise image editing. The GPT Image 1.5 API allows developers to generate and edit images programmatically within their own products.

Compared to GPT Image 1, the GPT Image 1.5 API provides more precise image editing, stronger instruction following, improved text rendering, and more consistent preservation of visual details. It also delivers faster generation and lower image input/output costs, making it better suited for production workloads.

Both are strong AI image models, but they emphasize different strengths. GPT Image 1.5 tends to be better for instruction-following and iterative editing, while Nano Banana Pro is often reported to perform better on certain languages and highly photorealistic renders. For production, the best choice depends on your specific prompts and templates.

When using the GPT Image 1.5 API on Kie.ai, you can manage API keys with usage limits, IP whitelisting, and monitoring tools. These controls help secure access and prevent unexpected usage in production environments.

You can find detailed GPT Image 1.5 API documentation on Kie.ai, including request structure, supported parameters, asynchronous task handling, callbacks, and usage guidelines. The documentation is designed to help developers integrate the API quickly and correctly.

You can test the GPT Image 1.5 API in the Kie.ai Playground before integrating it into your application. New users receive free credits, allowing you to experiment with text-to-image and image-to-image workflows without upfront cost.

Yes. The GPT Image 1.5 API on Kie.ai is built to support asynchronous execution and high-concurrency workloads. This makes it suitable for SaaS platforms, automation pipelines, and backend systems that require reliable performance under load.
