GPTi2 Store

GPTi2 Store is an AI image generation and editing service that operates with a transparent pay-per-image pricing model, charging 50đ for 1K, 60đ for 2K, and 80đ for 4K resolutions. The platform offers three quality tiers for each resolution and allows users to edit or reference up to eight source images per generation, with an additional 60đ fee for each reference image used. New accounts receive three free generation attempts as a welcome bonus, and all generated images are automatically deleted after 24 hours to ensure privacy.

The service supports both Vietnamese and English prompts, allowing users to describe images in either language without restriction. It provides a standard OpenAI API compatible with existing development workflows, requiring only a base URL change and an API key to integrate the SDK immediately. The API includes endpoints for generating images, editing images, and managing asynchronous jobs for larger files, along with balance and usage tracking tools.

Users can select from three aspect ratios and resolutions ranging from 1K up to 3840×2160 (4K) to suit their specific visual needs. The pricing is displayed clearly before any generation occurs, ensuring there are no hidden monthly fees or subscription costs. The system supports idempotency keys to prevent double charging if a request is retried, guaranteeing that the same image is returned without extra cost.

The platform offers several specialized models including gpt-image-2, gpt-image-2.5-flare, and gpt-image-2.5-sunburst, each designed for different visual styles. Newer versions like gpt-image-2.6-flare and gpt-image-2.6-sunburst are also available with distinct pricing structures for their low, medium, and high quality tiers. Users can view current model pricing by accessing the GET /v1/pricing endpoint within the API.

New users can start immediately by visiting the website, where they can claim their three free trial images without needing to provide a credit card. The process involves selecting a prompt, choosing a resolution, and clicking generate, with the cost deducted only after the image is created. There is no long-term commitment required, as the service operates on a simple pay-per-use basis.

The service allows users to upload up to eight reference images to guide the AI in editing or maintaining a specific style. Each reference image added to a generation request incurs an extra 60đ fee. This feature is particularly useful for creating consistent branding materials or modifying existing artwork while preserving the original aesthetic.

The platform provides a free trial consisting of three image generations for new accounts, which can be used to test different prompts and models. These free credits are automatically applied to the user's account upon registration, requiring no payment method to be entered initially. After the trial, users pay only for the images they actually generate, with costs varying based on the selected resolution.

Generated images are stored temporarily for a period of 24 hours, after which they are automatically deleted from the system. This short retention period ensures that user data remains private and is not retained indefinitely. The temporary storage allows users to view their creations on multiple devices before the automatic cleanup occurs.

The service includes a nano banana model option that costs between 80đ and 100đ per image, offering a faster and more affordable alternative for simple generation tasks. This model is accessed via the POST/v1/images/nano/generations endpoint and is suitable for quick, low-resolution outputs. It operates alongside the main gpt-image-2 and 2.5 models for users seeking cost-effective solutions.

The API supports asynchronous job processing for large images, allowing users to submit requests without waiting for immediate completion. Users can track the status of these jobs through the API and retrieve the final images once the processing is finished. This feature is essential for handling high-resolution 4K generations that require more time to render.

The platform enforces a limit of four images per generation request to maintain efficiency and quality. Additionally, users can retry failed requests using an idempotency key, which ensures the system does not charge extra fees for the same image generation. This retry mechanism is built into the API to handle network interruptions gracefully.

The service operates with a default private setting, meaning that generated images are not publicly visible unless the user chooses to share them. This privacy feature is standard for all accounts and helps protect the intellectual property of the designs created. Users can also choose to keep their work entirely within their own session.

The platform supports a variety of image styles including landscapes, 3D characters, food photography, and minimalist posters. Users can input detailed descriptions to achieve specific artistic outcomes, such as creating a scenic view of Ha Long Bay at sunrise or a minimalist coffee brand logo. The flexibility allows for diverse creative applications across different industries.

The service is designed for both individual creators and development teams, offering a user-friendly interface alongside a robust API for technical users. It provides clear pricing per image, eliminating the need for monthly subscriptions or hidden fees. The combination of ease of use and developer tools makes it accessible for a wide range of users.
