GPT-Image-2
Overview
GPT-Image-2 is an OpenAI image generation and editing model. It accepts text prompts and reference images, and is designed for creative production, marketing assets, and high-quality visual content.
Billing Method
GPT-Image-2 is billed by usage across text input, cached text input, image input, cached image input, and image output tokens. It does not have a single fixed price per generated image. Resolution, quality, aspect ratio, reference images, and output count can affect the final token usage.
Key Features
- Flexible aspect ratios: Supports auto, 16:9, 3:2, 1:1, 2:3, and 9:16.
- Multiple output specifications: Supports 1K, 2K, and 4K resolutions with Auto, low, medium, and high quality levels.
- Batch generation: Generates 1 to 8 images in a single request.
- Reference-image editing: Accepts up to 16 reference images for high-fidelity editing.
- Cost control: Resolution, quality, and output count can be adjusted for different production requirements.
Best Use Cases
- Marketing graphics, posters, banners, covers, and social media assets
- Product concepts, character designs, and visual style exploration
- High-resolution creative assets that require detailed rendering
- Image editing based on one or more reference images
- Batch generation of multiple candidates for comparison

Pricing
Prices are based on token usage. Under the platform-wide conversion of 1 USD = 1,000,000 Credits, a provider reference price of USD X / 1M Tokens corresponds numerically to X Credits/Token.
| Billing item | Reference price (USD/1M Tokens) | B.AI rate (Credits/Token) | How it is billed |
|---|---|---|---|
| Text input | 5.00 | 5.00 | Based on text input tokens |
| Cached text input | 1.25 | 1.25 | Applied when cached text input is reused |
| Reference-image input | 8.00 | 8.00 | Based on image input tokens; multiple images accumulate usage |
| Cached image input | 2.00 | 2.00 | Applied when cached image input is reused |
| Image output | 30.00 | 30.00 | Based on generated image output tokens |
Pricing note: Documented prices are B.AI standard reference prices for basic billing guidance. B.AI may provide a lower effective usage cost through top-up rewards or account benefits. Prices, bonus Credits, account benefits, and final settlement are subject to the platform display and billing records.
